摘要
ElNino事件是指赤道东太平洋的水温异常升高的现象,是造成全球气候异常的重要因子.利用温州的降水资料分析了近50年来温州降水对ElNino事件的响应,结果发现,ElNino事件显著地影响了处在太平洋西岸的温州气候.其中ElNino事件与温州年降雨总量、5～9月汛期降雨量、3～5月春季降雨量、10～11月秋季降雨量和暴雨天数等气象要素之间有着显著的相关关系.利用这种相关性规律,可以为中长期天气预测和防汛抗旱决策提供一些参考依据.
El Nino events,which are phenomena about the seasurface temperature rised unconventionally at the eastern equatorial Pacific, are important factors making the global climate abnormal.Text analyze the echo between Wenzhou precipitation to El Nino events near fifty years.The results show that El Nino events observably affact climate of Wenzhou located at the west shore of Pacific.There is remarkable correlativity between El Nino events and weather elements of Wenzhou,e.g. annual precipitation,flood season precipitation ( May to September )?spring precipitation ( March to May )?autumn precipitation ( October to November ) and number of days rainstorm,etc.Making use of this correlation,we can offer some scientific consulting gists to the midlong weather forecast and decisionmaking of flood prevention or fight a drought.
