| 摘 要： | 分析了1953～2001年杭州梅雨量的周期性振荡特征度其与赤道平流层纬向风之间的关系．结果表明，杭州梅雨量的变化存在着22年左右和准两年左右的周期振荡，雨量和赤道平流层纬向风的准二年振荡（QBO）之间具有相关关系，其相关关系受到太阳活动的调控．在厄尔尼诺年的同期或者后期，QBO和梅雨之间的关系往往会出现异常．

| Abstract: | Based on Meiyu precipitation data in Hangzhou from 1953 to 2001,the interannual and interdecadal oscillation of Meiyu precipitation is investigated.The results show that the precipitation of Meiyu in Hangzhou presents prominent quasi-22 year oscillation and quasi-biennial oscillation.By analyzing the correlation between the precipitantion of Meiyu in Hangzhou and Quasi-Biennial Oscillation(QBO) of zonal wind on 50 hPa over the equator,it is showed that there is a significant correspondence between the correlation and the 11-year sunspot cycle except in the phases of El Nino's occurrence. |
