From September to April the following year, dry and cold winter monsoons blow from Siberia and the Mongolian Plateau, resulting in cold and dry winters and great differences in the temperatures of north and south China. From April to September, warm and humid summer monsoons blow from the seas in the east and south, resulting in overall high temperatures and plentiful rainfall, and little differences in the temperatures of north and south China.

In terms of temperature, the nation can be sectored from south to north into equatorial, tropical, subtropical, warm-temperate, temperate, and cold-temperate zones. Precipitation gradually declines from the southeastern coastal areas to the northwestern inland areas , and the average annual precipitation varies greatly from place to place. In southeastern coastal areas, it reaches over 1,500 mm, while in northwestern areas, it drops to below 200 mm.
East-moving winds often carry soil away from China’s northwest, where overplowing and overgrazing, coupled with periods of drought, has led to massive deterioration of the country’s agricultural resources.

Huge dust plumes regularly travel hundreds of miles to Beijing and other cities in northeastern China. As they move over urban centers they pick up particles from industrial pollution.

The resulting dust clouds are often so thick they obscure the sun, reduce visibility, slow traffic, and close airports. Residents caulk windows with old rags to keep out the dust, and municipal crews have to clean public structures repeatedly during the dust-storm season.

The dust clouds are also a problem for China’s neighbors, and North Korea, South Korea, and Japan have registered official complaints. Responding to pressure from their citizens, legislators from Japan and South Korea are organizing a tri-national committee with Chinese lawmakers to devise a strategy to combat the dust.

The growing severity of the dust clouds has raised world concern.
