Climate types in the United States

The United States is located in the north temperate zone, between 25 degrees and 49 degrees north latitude. Most areas belong to temperate and subtropical zones. The climate and precipitation are suitable, and the precipitation and groundwater are very rich, which is conducive to the development of industrial and agricultural production. Only the southern tip of Florida Peninsula is tropical; Alaska is located between 60 and 70 degrees north latitude and belongs to the cold climate zone in the Arctic Circle. Hawaii is located in the south of the Tropic of Cancer and belongs to the tropical region. Due to the vast territory, complex terrain and the influence of different air currents, the climate varies greatly from place to place: when the Florida Peninsula is in the season of blooming, the Great Lakes in the north are still cold. The northeast coast and the Great Lakes belong to temperate continental climate. Due to the influence of Labrador cold current and cold air in the north, the winter cold season is longer. The monthly average temperature in 65438+ 10 is about-16℃, and the annual average precipitation is1000 mm. The southeast has a subtropical monsoon humid climate. It's warm and humid here because of the Gulf Stream. The average temperature of 65438+ 10 is about 9℃ in October and 24℃-27℃ in July. In late summer and early autumn, hurricanes often hit the Gulf Coast. The annual average precipitation is above1500mm. The climate of Central China Plain basically belongs to temperate continental climate, with Leng Xia hot in winter, high temperature and high humidity. The annual precipitation in the south of the central plain affected by the Atlantic Ocean and the Gulf of Mexico is as high as1500mm. Although the average temperature here is very high, it is often hit by a cold current from the north. The annual frost-free period in this area is about 160 ~ 200 days. The annual temperature difference in the dry western plateau is as high as 25℃, and the higher the mountain, the lower the climate. Latitude difference also has a great influence on the average temperature. From Columbia Plateau to Colorado Plateau, the average temperature in winter is high 10℃, especially in summer. The average annual precipitation is below 500 mm, the precipitation in plateau desert area is less than 250 mm, and the northern part of the Pacific coast is a temperate maritime climate zone with warm winter and cool summer and abundant rainfall. 5438+ 10 The average temperature in June is above 4℃, and the average temperature in August is below 22℃. The annual average precipitation is1300mm-1500mm. The southern section of the Pacific coast belongs to the subtropical Mediterranean climate, with hot and dry summers and mild and rainy winters. The climate in the United States is superior, and most areas are conducive to the growth of crops. But natural disasters also happen from time to time. Every year from May to 10, hurricanes often occur along the coast of the Gulf of Mexico, while the northern part of the Rocky Mountains is often hit by cold waves in winter, and sometimes even strong winds above 12 occur. Tornadoes in the United States mostly occur in spring and summer. In February and March, the warm and humid air flow in the Gulf of Mexico moved northward, and its influence ranged from Texas to Florida Peninsula. Every May, tornadoes hit Oklahoma, Arkansas and other states; In June, tornadoes hit Nebraska and Iowa.
