United States climate

from Wikipedia, the free encyclopedia

The climate in the United States is extremely diverse. There are several climate zones , such as B. the continental, subtropical, Mediterranean and in southern Florida tropical climate.

General

The northern regions, from Washington State to Maine , have a moderate, temperate climate. Winters can be very cool (values ​​below 0 ° C are not uncommon) - in summer, however, heat waves with temperatures above 35 ° C can often occur. The amount of precipitation is evenly distributed over the whole year; the winters are always accompanied by snowfall. The highest temperature ever recorded in New York was 43 ° C (108 ° F), while the lowest was only −26 ° C. The climate changes the further south you look: if it is still cool and temperate in the north, in the southern states one speaks of a subtropical climate - such as in Texas , Louisiana , Mississippi , Georgia and large parts of Florida . The south of Florida, including the Keys , is already tropical with rainy and dry seasons . Since the state of California borders directly on the Pacific Ocean, this zone is known as the Mediterranean climate .

Temperatures

The temperatures in the United States are very diverse. In the north, winters can be bitterly cold (around -10 ° C) and summers can be mild to hot (+25 to +32 ° C). In a southerly direction, the winters are rather mild at around +10 ° C and the summers (around +35 ° C) are very hot. The desert regions of the states (e.g. California , Utah , Texas ) are extreme during the day (40 ° C) in summer, but cool down significantly at night (approx. 19 to 20 ° C). In winter, even in the desert, it is mostly cool (15 ° C during the day, sometimes minus degrees at night). The winter temperatures in Salt Lake City make the area around the city ideal for winter sports.

The earthquake area, for example, is typical of California - in the south, especially from May to October, sometimes violent tropical storms ( hurricanes ) occur. Other environmental disasters occurring in the USA are blizzards, tornadoes, floods, etc.
