The chief climate characteristics in 2002 are showed as following: in most areas, the annual precipitation was more than normal but the distribution was uneven in time and space. Droughts appeared widely in the northern part of China during early spring and hot Autumn days and also occurred along the coast of south China from winter/spring to the beginning of summer due to the less rainfall. In the flood season, no heavy rainfall and floods happened in extensive regions but the spring flood appeared in the middle and lower reaches of the Changjiang River. The rain season began earlier than normal in North China. In some areas of South China, heavy rainfall, floods, mountain torrents, mud rock flows and landslides caused severe damages. The mean annual temperature was higher than normal in most areas and the fluctuation of temperature was fairly obvious. The sandstorm weather was concentrative in time and led to wide and serious influences. The landing typhoons number (including the tropical cyclones,storms) is near normal, strong convective weather such as hails and tornadoes occurred more than normal.
