Abstract:As for 2004, the annual total precipitation mean by whole country is less than usually annual quantity and uneven in spatial and temporal distribution. From the spring to the beginning of the summer, the heaviest drought occurred in the area of the west of Northeast and the east of inner-Mongolia in 2004 of the last 50 years, while as to the autumn, the heaviest drought on a large scale occurred in the south of China and the middle and lower reaches of Yangtze River. In the flood season, there was no heavy flood disaster in a valley scale in the main river of our country, but heavy rain, flood, surged slope, and mud-stone flow caused by locally heavy rain occurred very frequently. The loss caused by these disasters was serious in Sichuan, Chongqing, Yunnan, Henan, Hubei, Hunan provinces, and so on. Annual mean temperature on the whole country scale was on the obvious higher than usually annual mean temperature, but staggered undulation of temperature was obvious. Parts of area encountered low temperature disaster or snow disaster in the winter, the spring and the fall. The south maintained durative high temperature in the summer. Eight typhoons (tropical storm) landed in 2004. Thereinto, the typhoon named Yunna caused serious damage in Zhejiang Province. The locally strong convective weather such as thunder rain and heavy wind as well as hailstone and lightning strike occurred frequently. The dust weather increased compared with the corresponding period of last year. As a whole, the climate in 2004 is natural, and the meteorological disaster is less. In short, 2004 is a better meteorological year.
