| 摘 要： | 利用1981—2010年江苏沿海地区的大风资料,分析30 a沿海大风气候特征,结果表明:江苏沿海地区最大风速≥6级和≥8级大风,呈逐年递减趋势。夏季,江苏沿海大风以东南风为主;秋、冬季,以偏北风为主;而春季,沿海大风以偏北风为主,东南风次多。冷空气偏北大风以冬季最为常见,低压(气旋)大风和入海高压后部大风易发生在春、夏两季,雷雨大风主要发生在夏季,台风大风主要发生在夏季和秋季。

| Abstract: | By using the wind data of Jiangsu coast areas from 1981 to 2010, coast gale climate characteristics for 30 a were analyzed. The analysis indicates that days of wind speed above 6 and 8 categories in one year reduced successively. The southeast wind is the majority in summer, while the north wind is the majority in autumn and winter, however in spring, the north wind is the majority and the southeast wind is second. The north wind caused by cold air is common in winer, and the wind caused by low pressure or located in the back of high pressure usually happen in spring and summer. The thunderstorm gale occurs mainly in summer, and the wind caused by tropical cyclones is common in summer and autumn. |
