As in other temperate desert climates, the dry air results in large differences (sometimes over 40 degrees) between daytime high and nighttime low temperatures. In Washington, the average annual temperature is 13.3 °C. Upwelling of cold Pacific waters also contributes to the frequent cool spring and early summer weather in coastal California. [22] The Sonoran Desert in the southwest is home to the driest locale in the US. Climate at a Glance. Here there are four distinct seasons, with warm to hot summers, and cold and often-snowy winters. The land in North America is actually still adjusting to the loss of ice after the last ice age, which peaked about 20,000 years ago. The strip of land from north Texas north to Nebraska and east into Southern Michigan is known as Tornado Alley, where many houses have tornado shelters and where many towns have tornado sirens. Taken with other recent research showing that the most habitable climate in North America will shift northward and the incidence of large fires will increase across the country, this suggests that the climate crisis will profoundly interrupt the way we live and farm in the United States. These include tropical at sea level, arid, semi-arid, temperate, and alpine at the highest elevations. Farmland failed throughout the Plains, entire regions were virtually depopulated, and dust storms ravaged the land. 97-37 NOVEMBER 21, 1997: El Niño and California Precipitation. The primary drivers of weather in the contiguous United States are the seasonal change in the solar angle, the migration north/south of the subtropical highs, and the seasonal change in the position of the polar jet stream. The Southwest has the worst droughts; one is thought to have lasted over 500 years and to have decimated the Anasazi people. Other products help define climate trends and variability over time. In California's inland river valleys (Bakersfield, Sacramento areas), the wet-winter, dry-summer pattern remains, but winters are cooler and more prone to occasional frost or freeze, while summers are much hotter, with blazing sunshine and daytime high temperatures not uncommonly in the 90s to over 100 °F (38 °C). The United States of America is a federal republic of fifty states, a federal district, and several territories. The Gulf and South Atlantic states have a humid subtropical climate with mostly mild winters and hot, humid summers. Land & Climate Land North America covers about 24,249,000 square kilometres, or about a sixth of the world's land area. The average snow to liquid ratio across the contiguous United States is 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water. Primarily from August to early October, the coastal Gulf and South Atlantic states are susceptible to being struck by tropical weather systems (tropical depressions, tropical storms, and hurricanes). [17], In northern Alaska, tundra and arctic conditions predominate, and the temperature has fallen as low as −80 °F (−62 °C). When winter-season Canadian cold air masses drop unusually far southward, "Gulf lows" can develop in or near the Gulf of Mexico, then track eastward or northeastward across the Southern states, or nearby Gulf or South Atlantic waters. Lake-effect snows add to precipitation potential downwind of the Great Lakes,[9] as well as Great Salt Lake and the Finger Lakes during the cold season. The average annual rainfall is 1023 mm. Some exceptions include the Great Mississippi Flood of 1927, the Great Flood of 1993, and widespread flooding and mudslides caused by the 1982–83 El Niño event in the western United States. Precipitation (whether by annual amount, annual distribution or characteristic[s]) varies significantly across the United States and its possessions. Cities like Phoenix, Las Vegas, Yuma, and Palm Springs have average highs over 100 °F (38 °C) during the summer months and lows in the 70s or even 80s. In the Northern Hemisphere summer, high pressure in the Pacific Ocean builds toward the California coast, resulting in a northwesterly airflow, creating the cool, dry, and stable weather conditions prevalent along the West Coast in summer. Generally, the area at greatest risk for tornadoes migrates northward from February to June, peaking in the Gulf States in February and March, the Ohio Valley and lower Midwest in April, southern and central Plains and central Midwest in May, and Northern Plains and upper Midwest (Dakotas, Minnesota, and Wisconsin) in June. Displaying top 8 worksheets found for - Climate Of The United States. The Gulf of Alaska is the origination area of many storms that enter the United States. Both the Appalachian region and the Midwest experience the worst floods. Office of Global Change (EGC): The Office of Global Change leads on U.S. international climate change policy and represents the United States in climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) and in other international fora, including the Intergovernmental Panel on Climate Change, International Civil Aviation Organization and the International Maritime … Coastal areas of Oregon and Washington have an oceanic climate. at Boise, ID), with annual precipitation averaging less than 15 inches (380 mm) as a result of the rain shadow of the Sierra Nevada and Cascades. Dallas, Austin and San Antonio areas) have average daily highs in the mid to upper 90s F. In winter, average daily high temperatures range from the 40 °F (4 °C)s (upper South: northern Arkansas, Kentucky and Virginia), to the 60 °F (16 °C)s along the Gulf Coast and South Atlantic coast (Charleston southward), with 70 °F (21 °C)s in central Florida and far southern Texas. Satellite view of the contiguous United States, Statistical Weather and Climate Information. The southern tip of Florida is tropical, as is Hawaii. Mailing Address. The U.S. Virgin Islands have a tropical savanna climate, with warm, dry winters, and rainy summers (Köppen Aw), typical of the Caribbean. From 1979 to 2002, 16,555 deaths occurred due to exposure to excessive cold temperatures, a mean of 689 per year. [5] Snow sometimes occurs in high mountain areas. Widespread severe flooding is rare. West of 100°W, much of the U.S. has a cold semi-arid climate in the interior upper western states (Idaho to the Dakotas), to warm to hot desert and semi-arid climates in the southwestern U.S. East of 100°W, the climate is humid continental in northern areas (locations roughly above 40°N, Northern Plains, Midwest, Great Lakes, New England), transitioning into a humid temperate climate from the Southern Plains and lower Midwest east to the Middle Atlantic states (Virginia to southern Connecticut). As such, the warmest summer weather is delayed until August, even September in many areas of the California coast; on average, September is the warmest month in San Francisco, CA. Weather systems, be they high-pressure systems (anticyclones), low-pressure systems (cyclones) or fronts (boundaries between air masses of differing temperature, humidity and most commonly, both) are faster-moving and more intense in the winter/colder months than in the summer/warmer months, when the belt of lows and storms generally moves into southern Canada. The Great Basin and Columbia Plateau (the Intermontane Plateaus) are arid or semiarid regions, with high summer temperatures in the 90s to occasionally over 100 at lower elevations (e.g. The Southwest has a hot desert climate, at lower elevations. If you look at the map on page 125, you will see that the United States has more climate zones than Canada. [citation needed] Both coastal and interior areas of Oregon and Washington, and southern Idaho, have a wet-winter, dry-summer precipitation pattern, but traveling eastward into Montana and Wyoming, this transitions progressively (for example, at Missoula, MT) toward relatively drier winters and a May and eventually June precipitation maximum, the latter characteristic of the Northern Plains and much of the upper Midwest (i.e. New Orleans, LA, Mobile, AL and Pensacola, FL areas), and in South Atlantic coastal and sandhills areas (i.e. The climate in the extreme north of Alaska is what would be expected for an area north of the Arctic Circle — it is an Arctic climate (Köppen ET) with long, very cold winters and short, cool summers. Spring (March- May) and autumn (September-November) are generally cooler, more comfortable times to visit. Still, drought has been frequent in the region, often lasting for periods of years or longer. We apologize for any inconvenience. This is a book to encourage and inspire climate educators of all types to know that they are not alone, but are instead … Columbia, SC, Fayetteville, NC, Raleigh, NC, Wilmington, NC, and Norfolk, VA), July and August are usually the wettest months, and precipitation is fairly evenly distributed the rest of the year. A climate migration is a familiar theme in the news … The wet season is from May to October. Temperatures in the United States are expected to continue to rise. A humid subtropical climate is found along and south of a mostly east-west line from the Virginia/Maryland capes (north of the greater Norfolk, Virginia area), westward to approximately northern Oklahoma, north of the greater Oklahoma City area. Climate of the U.S. Satellite view of the contiguous United States. Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time. The Arctic, Atlantic, and Pacific oceans border the three sides. Minnesota/North Dakota). The climate of the United States varies due to changes in latitude, and a range of geographic features, including mountains and deserts. Cities in this area include Minneapolis, MN, Omaha, NE, Sioux Falls, SD, Fargo, ND, Chicago, IL, Cleveland, OH, Buffalo, NY, Albany, NY, Boston, MA, Concord, NH and Augusta, ME. The Southwest has a hot desert climate, at lower elevations. Reflecting these air-mass conflicts, central Oklahoma, including the Oklahoma City and Moore-Norman areas, has the highest frequency of tornadoes per unit land area on planet Earth, with May the highest-risk month for tornadoes throughout "Tornado Alley," from northern Texas north-northeastward toward western and central Iowa. Teaching Climate Change in the United States is the first-of-its-kind effort to show the breadth and depth at which true climate education – education that engages and empowers young people to take on the defining crisis of our time – is already happening across our country. Precipitation is spread fairly evenly throughout the year, though as one travels from Indiana westward there is an increasingly prominent early-summer concentration, with a May maximum in northern Texas and Oklahoma, and a June maximum increasingly evident from (central/northern) Indiana westward to Kansas. As one travels from east to west across Nebraska, South Dakota and North Dakota, average annual precipitation steadily decreases, and the westernmost counties of these states have a semi-arid climate, with about or just over 15 inches of precipitation per year, on average (see climate data for Williston, ND, Rapid City, SD and Scottsbluff, NE). Localized flooding can, however, occur anywhere. In the Northern Hemisphere winter, the subtropical highs retreat southward. To the east of the 100th meridian, the climate ranges from humid continental in the north to humid subtropical in the south. In 2015, the Wall Street Journal reported that U.S. territories such as Puerto Rico are the areas of the U.S. most vulnerable to climate change. Lows range from the 60 °F (16 °C)s in summer to 25 to 35 °F (−4 to 2 °C) in winter. In the Great Lakes states, cold Arctic air in winter crossing the relatively warmer lake waters can result in frequent and sometimes very heavy lake-effect snow, especially on the eastern and southern shores of the Great Lakes (for example, in western Michigan's Lower Peninsula and in the Buffalo, NY area). [32], Varies due to changes in latitude, and a range of geographic features, Gulf Coast/Lower Mississippi Valley/South Atlantic states, Southern Plains/Lower Midwest/Middle East Coast, Northern Great Plains/North-Central/Great Lakes/New England. In winter, daily temperatures in the southwest are cooler with highs in the 50s and 60s F, and lows in the 40s F. In Phoenix, Las Vegas and similar Southwestern desert areas, on average June is the driest month, after Pacific-originating winter storms have concluded and before the Southwestern summer "monsoon" begins. Daytime highs range from 80 to 90 °F (27 to 32 °C) in summer to 35 to 50 °F (2 to 10 °C) in winter. From May to August especially, often-overnight mesoscale-convective-system (MCS) thunderstorm complexes, usually associated with frontal activity, can deliver significant to flooding rainfall amounts from the Dakotas/Nebraska eastward across Iowa/Minnesota to the Great Lakes states. The Köppen-Geiger climate classification is Cfa. Daily high temperatures range from 70 to 80 °F (21 to 27 °C) in the summer to 50 to 65 °F (10 to 16 °C) in winter, with low temperatures from the 60 °F (16 °C)s in summer to the mid 40s F in winter. The dry season is from January to May, and the wet season from July to November. They sometimes bring rain, but can bring snow or ice across the South, mostly in interior or northern areas. La Niña Impacts in the Pacific Northwest. A disproportionate number of men, a full 68% of deaths, versus women have been affected. [citation needed] Like most Mediterranean climates, much of coastal California has a wet winter and dry summer. https://www.lonelyplanet.com/american-samoa/attractions/rainmaker-mountain/a/poi-sig/1456093/362248, Precipitation History of the Mojave Desert Region, 1893–2001, https://www.washingtonpost.com/gdpr-consent/?destination=%2fweather%2f2019%2f10%2f31%2farctic-chill-blasts-east-bringing-early-dose-winter-record-cold%2f%3f, https://electroverse.net/the-continental-u-s-just-set-its-coldest-ever-october-temperature/, https://www.climatedepot.com/2019/10/30/utah-sees-record-cold-of-43-6-of-may-be-lowest-october-temperature-ever-recorded-in-continental-u-s/, "Climate at a Glance: National Centers for Environmental Information", Large Floods in the United States: Where They Happen and Why, QuickStats: Number of Heat-Related Deaths,* by Sex — National Vital Statistics System, United States,† 1999–2010§, Hypothermia-Related Deaths - United States, 2003-2004, https://en.wikipedia.org/w/index.php?title=Climate_of_the_United_States&oldid=991929319, Short description is different from Wikidata, Articles lacking in-text citations from June 2020, All Wikipedia articles written in American English, Articles with unsourced statements from July 2018, Articles to be expanded from January 2019, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 December 2020, at 15:56. On the other hand, Nor'easter snowstorms can bring activity to a halt in both the New England and Great Lakes regions. Further eastward in the desert Southwest (Tucson, AZ eastward toward El Paso, TX), winter-season precipitation decreases, while the summer monsoon increasingly provides a summer precipitation maximum. Distribution of Mesoscale Convective Complex Rainfall in the United States. Areas in the southern U.S. (Florida, the Gulf Coast, the Desert Southwest, and southern California) however, often have more stable weather, as the polar jet stream's impact does not usually reach that far south. "[4]<, Hawaii has 11 different climate zones, influenced by altitude and topographical effect on wind and rainfall. In the northern Plains and North Central states generally, June is the year's wettest month on average, owing to maximum shower and thunderstorm activity. [11][12][13][14], During the summer, the Southwest monsoon combined with Gulf of California and Gulf of Mexico moisture moving around the subtropical ridge in the Atlantic Ocean bring the promise of afternoon and evening thunderstorms to the southern tier of the country as well as the Great Plains. Large thunderstorm areas known as mesoscale convective complexes move through the Plains, Midwest, and Great Lakes during the warm season, contributing up to 10% of the annual precipitation to the region. The summer months (June-August) are generally hot regardless of the … [31] In terms of deaths caused by cold waves, the same gender inequality exists; 66% of hypothermia-related deaths in 2002 were of males. There are no fewer than nine regional climates in the United States. Guam and the Northern Mariana Islands both have a trade-wind tropical rainforest climate (Köppen Af). The northern half of the Great Plains (Nebraska northward), northern Midwest, Great Lakes, and New England states have a humid continental climate. Most of the maps were adapted from the Climatic Atlas of the United States and modified to make them easier to use. These climates normally lie on the southeast side of all continents, generally between latitudes 25° and 35° and are located poleward from adjacent tropical climates.. This supports rainforests like El Yunque. West Coast Cold Season Heavy Rainfall Events. The greatest annual snowfall level is at Mount Rainier in Washington, at 692 inches (1,758 cm); the record there was 1,122 inches (2,850 cm) in the winter of 1971–72. The Great Plains west of the 100th meridian … The Southwest and the Great Basin are affected by said monsoon from the Gulf of California from July–September. on the prevailing windward side, of the Olympic and Cascade mountain ranges), experiences a mostly overcast, wet and cool climate, but without severe cold like that found in the interior northern U.S. (i.e. [21] Pago Pago Harbor in American Samoa is the rainiest harbor in the world (because of the 523 meter Rainmaker Mountain). In the Atlantic Ocean, the Bermuda High creates a south-southwest flow of tropical air masses over the southeastern, south-central and central United States - resulting in warm to hot temperatures, high humidity and frequent intense (but usually brief) showers and/or thunderstorms as the heat builds in the afternoon. On average, the wettest month is typically November or December; the driest, July. From late summer into fall (mostly August to October), tropical cyclones (hurricanes, tropical storms and tropical depressions) sometimes approach or cross the Gulf and Atlantic states, bringing high winds, heavy rainfall, and storm surges (often topped with battering waves) to Gulf and Atlantic lowlands and coastal areas. However, snow does occur even at the lowest elevations, primarily when Pacific moisture interacts with cold air intruding into the Pacific Northwest from western Canada (i.e. A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cold to mild winters. We are working to resolve the issue as soon as possible. FPO Global climate is changing and this change is apparent across a wide range of observations. In terms of deaths from heat waves, 7,415 losses occurred between 1999 and 2010, a mean of 618 per year. Precipitation, though scarce, often falls year-round, influenced both by summer thunderstorms brought by the Southwestern monsoon (primarily in southern areas), and by winter-season storms from the Pacific Ocean. The Urban Institute estimates more than 1.2 million Americans left their homes in 2018 for climate-related reasons — some were escaping long-term problems, but others were fleeing short-term disasters that became permanent displacements. Please note: Due to browser FTP deprecation, users will no longer be able to access NCEI data via browser FTP clients. The book summarizes the scientific literature with respect to climate impacts on the Southeast United States, including 11 southern states to the east of the Mississippi River, Puerto Rico, and the US Virgin Islands; reviews the historic climate, current climate, and the projected future climate of the region; and describes interactions with important sectors of the Southeast and cross-sectoral issues, namely … Southern Florida has a tropical climate, with all months having a mean temperature of higher than 65 °F (18 °C), a wet season from May through October, and a dry season from November through April. The United States of America, with its size of almost 10 million km² and a wide variety of landscapes, extends over numerous climate zones. both Dakotas, Nebraska, Iowa and Minnesota). Florida also reports many tornadoes, but these rarely are very strong. On average, the mountains of the western states receive the highest levels of snowfall on Earth. The highest yearly total of heat-related deaths during that time frame was in 1999. In the U.S., it was either warm and dry (Texas) or warm and wet (the Northeast).... 2012 Preview: According to the best long-range weather crystal balls currently available to modern science, 2012 is set to carry over some of the same weather and climate trends. A Mediterranean climate prevails along most of the California coast, while southern Florida has a tropical climate, the warmest region on the US mainland. Average overnight lows range from the upper 50 °F (10 °C)s in winter to the mid and upper 70 °F (21 °C)s in summer. In the lower Midwest (and southern Plains states, especially), temperatures can rise or drop rapidly; winds can be extreme; and clashing air masses, including hot, dry air of Mexican and/or Southwestern origin, warm, moist air from the Gulf of Mexico and cold, dry air from Canada can spawn severe thunderstorms and tornadoes, particularly from April to June. Walker S. Ashley, Thomas L. Mote, P. Grady Dixon, Sharon L. Trotter, Emily J. Powell, Joshua D. Durkee, and Andrew J. Grundstein. The Interior Plains cover much of central Canada and the Midwestern United States. In addition, much of the land along the Atlantic coast is sinking, which magnifies the local effect of sea level rise. Stretching across Mississippi and Alabama, Dixie Alley has experienced both tornadoes and violent thunderstorms, with peak tornado season coming on as early as February and waning by May. [7], See also: Climate of American Samoa, Climate of Guam, Climate of the Northern Mariana Islands. The "dryline," separating hot, dry air of Mexican/Southwestern U.S. origin from warm, moist air from the Gulf of Mexico, often causes severe, occasionally violent, thunderstorms to fire in central and eastern Texas, Oklahoma and Kansas; these sometimes contribute toward the hailstorms and tornado outbreaks that the Southern Plains are well known for. The climate here is mild, and generally warm and temperate. Climate Normals define the climate of a place during a time of year. Other shared climate and vegetation zones are found along their joint border at the southern end of Canada and the northern end of the United States. The climate is wet and cool in autumn, winter, and spring, and stable and drier in the summer months, especially July and August. Formerly the National Climatic Data Center (NCDC)…. Summer high temperatures often reach the 90s, but low temperatures drop into the low 60s and even 50s. Because of contrasting air masses, the Great Plains, the Midwest, and the southern United States have frequent severe thunderstorms and tornado outbreaks during both the spring and the summer. In fact, climate migration was already well underway in the United States before the latest round of fires. In the warm season, storm systems affecting a large area are less frequent, and weather conditions are more solar {sun} controlled, with the greatest chance for thunderstorm and severe weather activity during peak heating hours, mostly between 3 PM and 9 PM local time. [28] They usually can touch down during the spring and the summer. Yuma, Arizona, has an average of 2.63 inches (67 mm) of precipitation each year.[23]. However, in general it has a continental climate , with cold winters (often frigid) and hot summers (sometimes very hot), with a different season duration depending on latitude and distance from the sea. Puerto Rico has different climatic zones, all tropical. WASHINGTON — Au revoir, Paris Agreement.As of Wednesday, under United Nations rules, the United States is officially out of the global climate accord. Related climate and educational websites. The lowest was in 2004. Southern Florida is the warmest region of the U.S. mainland in winter. Late summer and fall extratropical cyclones bring a majority of the precipitation which falls across western, southern, and southeast Alaska annually. The southern part is drier, mostly a savanna climate (Köppen Aw) with small locations on the southern coast dry enough to have a hot-semi arid climate (Koppen BSh). Average daily lows in winter range from 20 °F (−7 °C)s north to 40 °F (4 °C)s along the Gulf and far South Atlantic coasts, with 50 °F (10 °C)s in Florida and coastal south Texas. Northern Arizona and New Mexico, central and northern Nevada and most of Utah (outside higher mountain areas) have a temperate semi-desert to desert climate, but with colder and snowier winters than in Phoenix and similar areas, and less-hot summers (as at Salt Lake City, Utah). Martin A. Baxter, Charles E. Graves, and James T. Moore. Climate Normals define the climate of a place during a time of year. Much of the interior South (Tennessee, Kentucky and the northern Gulf states) has a winter or spring maximum in precipitation, with December, March or April typically the wettest month, and August to October the driest months - for example, at Birmingham, AL, Huntsville, AL, Tupelo, MS and Memphis, TN. The polar jet stream (and associated conflict zone between cold, dry air masses from Canada and warm, moist air masses from the Gulf of Mexico) drops further southward into the United States - bringing more frequent periods of stormy weather, with rain, ice and snow, and much more variable temperatures, with rapid temperature rises and falls not uncommon. [20] Hawaii receives even more, with 404 inches (10,262 mm) measured annually, on average, at the Big Bog, in Maui. The eastern part of this flat, low-lying region is North America's most productive agricultural … US Climate; State map; United States Climate Page Click on state of interest. See https://docs.google.com/document/d/1JUra5HnsbR_xmtQctkb2iVxRPuhPWhMB5M_zpbuGxTY/edit as reference. Far western Texas (El Paso area) is desert, and average annual precipitation is less than twenty inches (510 mm) in westernmost Kansas and the Oklahoma Panhandle, where the climate qualifies as semi-arid. See also: Climate of Alaska, Climate change in southeast Alaska, The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate[2] (Köppen Cfb). While many subtropical climates tend to be located at or near coastal locations, in some cases they extend inland, most … The climates of the United States, the causes of these climates, and events of interest in the climatological history of the United States are described in the text and illustrated by many maps and diagrams. Like the southern end of the Northeast region, summer temperatures in the Midwest tend to be hot and very humid, averaging between 85 and 95 degrees with 50 percent (or more) humidity. The climate system within the United States varies by place and by time of year. Such "North Pacific lows" enter the U.S. through the Pacific Northwest, then move eastward across the northern Rocky Mountains, northern Great Plains, upper Midwest, Great Lakes and New England states. The continent is roughly triangular in shape. [10] The El Niño-Southern Oscillation affects the precipitation distribution, by altering rainfall patterns across the West, Midwest, the Southeast, and throughout the tropics. This results in some increase in humidity and cloud cover, bringing higher nighttime low temperatures and localized thunderstorms to the region, which can result in flash flooding. The state of Alaska, on the northwestern corner of the North American continent, is largely dominated by a subarctic climate, but with a subpolar oceanic climate in the southeast (Alaska Panhandle), southwestern peninsula and Aleutian Islands, and a polar climate in the north. In the summer, storms are much more localized, with short-duration thunderstorms common in many areas east of 100°W and south of 40°N. In the interior South, in cities like Raleigh, NC, Atlanta, Birmingham, AL, Nashville, TN and Jackson, average summer highs and lows are similar to coastal areas, while some areas of interior eastern and central Texas (i.e. The regions of the United States that have provided the most hospitable to human life and agriculture throughout human history on the continent will likely be abandoned in a ... Another article by Abrahm Lustgarten supplements the mapping project by exploring in detail the likelihood of a climate migration in the United States within this century. Rainmaker Mountain on Tutuila traps trade-wind rainclouds, leading to very high rainfall and a tropical rainforest climate (Köppen Af). Given the tropical air masses, summer-season thunderstorms can occur throughout the South, but they are heavier and more frequent along the Gulf Coast, South Atlantic coast (Norfolk, VA area southward), and in peninsular Florida. We have provided 2 differing Climate zone maps of the US with varying levels of detail. Other products help define climate trends and variability over time. Higher-elevation areas of the Rocky Mountains, the Wasatch Range, Sierra Nevada, and Cascade Range are alpine. Climatic Summary of Snowfall and Snow Depth in the Ohio Snowbelt at Chardron. This variety, ranging from tundra to tropical, occu… Northern Alaska has an arctic climate with temperatures up to 30°C below zero, while most of the land mass of the USA is in a continental temperate climate zone.
