摘　　要：2007年,中国年平均气温较常年偏高1.3℃,为1951年以来最暖的一年;平均年降水量接近常年。年内,我国气象灾害频发,淮河流域夏季发生特大暴雨洪涝,北方出现罕见秋雨;江南、华南发生五十年一遇特大秋旱;热带气旋登陆多、时间集中,损失接近常年,但死亡人数少;辽宁、山东初春遭遇强暴风雪(雨);局地强对流天气频发,雷击灾害伤亡重;春季北方地区沙尘天气少,出现时间集中。总的来看,2007年我国干旱面积偏大,暴雨洪涝损失重,城市内涝频发,雷击灾害伤亡多。The nationally averaged temperature in China for 2007 was 1.3℃ above the 1971 - 2000 long-term mean, ranking this year as the warmest since 1951. The averaged precipitation was close to normal, with considerable variability across the country and throughout the year. Huaihe River Valley was hit by severe flood in summer, and consecutive autumn rains occurred in northern China. Widespread droughts extended much of southern China in autumn. The number of landfalling tropical cyclones was more than normal, mainly occurred in August, September and October. The economic losses caused by tropical cyclones were near normal, while the number of dead was much less than normal. In early spring, Liaoning and Shandong was slashed by heavy snowstorm. Thunderstorm occurred frequently in some regions with many dead reports. The number of duststorm days was less than normal.
