摘要:

利用上海地区11个气象站雷暴资料,从时间和空间2方面分析了上海雷暴的气候特征和变化规律。结果表明, 1960~2008年期间,上海年平均雷暴日数总体上减少,其中秋季雷暴日数减少最为显著。在近30 a,雷暴日数更多地从9月向8月转移。空间上,全年雷暴日数在上海的西北、西南和东南方向减少较多,春季雷暴日数在西部和南部减少较多,夏季雷暴日数在西北部减少最多,秋季雷暴日数在南部减少最多。在本世纪初,上海徐家汇雷暴初日提早,终日没有明显变化,雷暴的初日、终日之间的日数总体上表现为增加。

Abstract:

Based on the thunderstorm data of 11 meteorological stations in Shanghai, the temporal and spatial climatic characteristics of thunderstorm in recent 50 yearswere analyzed. The results indicated that the annual total thunderstorm days p resented decreasing trend from 1960 to 2008, and especially obvious in autumn. In recent 30 years, thunderstorm days in Augustwere more than that of Sep tenber. In the whole year, the decrease of thunderstorm dayswasmore in the northwestern, southwestern and southeastern part of Shanghai, and in sp ring, summer and autumn, the decrease of thunderstorm dayswasmore in the western and southern part, the northwestern part, and the southern part of Shanghai, respectively. In the first 8 years of 21 st century, the first day of thunderstorm was earlier.but the last day changed insignificantly at Xujiahui station.
