Main weather systems causing temperature changes in the central plains of the United States

The central plains of the United States belong to a temperate continental climate, characterized by Leng Xia fever and little precipitation in winter.

The central plain lies between the Appalachian highlands and the Rocky Mountains. It starts from Hudson Bay on the US-Canada border in the north and reaches the Rio Grande in the Atlantic coastal plain in the south. There are many lakes and rapids in the northern half, and the Mississippi River Plain in the southern half, which is divided into two units: the eastern inland low plain and the western great plain. The middle part is the alluvial plain in the lower reaches of Mississippi River, and its southeast side, that is, the area south of Ohio River and east of Missouri River, is a low plateau. In the southwest are rolling hills and valleys. The western great plain is basically a vast plain, rising slowly from east to west, with an altitude of 500 meters to 1800 meters, and then rising abruptly to connect with the western mountains.

The land is vast and flat, the soil is deep and fertile, the water is abundant and the climate is mild. To enable the central plains of the United States to develop large-scale mechanized dry farming. The Central Plains is one of the world-famous agricultural areas, and the main crops are corn, wheat, rice, cotton, soybeans and tobacco. The output of soybeans, corn and wheat plays an important role in world agriculture. The northern part of the central plain of the United States is a wheat belt, mainly spring wheat, with cotton planted in the middle and winter wheat planted in the south.
