摘要
本文利用全省1961 2006年的大风天气资料和大风灾情资料,对大风灾情发生的地理分布特征,月、季、年的时间变化特征进行统计分析,并对其成因作了进一步研究,结果发现,自20世纪80年代开始,大风灾情日数年际变化大幅度增加,大风日数与大风灾情日数的地理分布基本一致,大风灾情日数季节变化明显。
Utilizing gale weather data and its disaster data from 1961 to 2006, we statistically analyze its geographical distribution and temporal changes of month, season and year and further study its causes of formation. The result shows that since 1980s yearly change of the day number of gale disaster increases greatly; geographic distribution of the day number of gale disaster consists with that of the day number of gale; seasonal change of the day number of gale disaster is significant.
