中国雷暴气候分布特征及变化趋势
Climate Characteristic and Variation Tendency of Thunderstorm in China
摘要
Abstract
Based on the observations from 1951 to 2005,the occurring days of thunderstorm and hail at 743 stations in China are examined. Results show that the occurring probability distributions of thunder-storm and hail in China have obvious differences of geographic location and daily variation. Distribution of severe convection weather changes obviously during the day and night. The thunderstorm occurrs frequently in five regions of China, namely eastern Qinghai-Xizang Plateau, middle and south of Yunnan, Sichuan, South China and west of Xinjiang, where there exists different interannual variations for the thunderstorm days of different regions. Except slight increasing in Qinghai-Tibet Plateau,the thunder-storm days present decreasing tendency in the other areas of China.The hail ocCULTS frequently in the Qinghai-Xizang Plateau and Qilian Mountains, secondly in Tianshan Mountains and northern part of North China. The interannual variation of hail days iS also different in different regions.REOF analysis results show that the thunderstorm days anomalies exist independent temporal and spatial distributions in South China,the Yangtze River Basin and so on,which are closely related to the specific large-scale circulation.关键词
