Abstract:In 2010, the annual mean temperature was 0.7 ℃ higher than normal, which ranked the 10th warmest year since 1961. And it was the warmest summer mean temperature since 1961. Annual precipitation in China was 681 mm, 11.1% more than normal, which ranked the second most since 1961. During this year, extreme weather and climate events happened frequently. Southwest China experienced the rare severe autumn-winter-spring drought. In winter and spring, unusual persistent low temperature hit Northeast and North China. The most serious snowstorm attacked northern Xinjiang, which broke the historical record. From May to July, heavy rainstorm attacked southern China 14 times. From mid July to early September, severe rainstorm and induced flood attacked northern and western China 10 times. In early and mid October, seldom consecutive heavy rainstorm appeared in Hainan Province. Serious geological hazards such as mountain torrents, mud rock flow and mudslide happened in Zhugqu of Gansu Province and other sporadic places. In summer, frequent hot waves happened widely and intensely. In early summer, the weather in Northeast China was very hot and the maximum temperature in many areas broke historical records. The number of tropical cyclones was below normal, while the proportion of landing was high. The affected regions concentrated in South China. Typhoons Chanthu and Fanapi brought serious losses. The worst strong wind and hail hazards in recent 20 years occurred in Chongqing and caused heavy casualties. In spring, the strong dust storm affected 21 provinces. In general, in 2010, the losses caused by meteorological hazards were the most since 2000. The direct economic losses and mortalities or the missing caused by meteorological hazards were the most in recent 10 years.
