南极涛动对福建前汛期降水的预测意义OA北大核心CSCDCSTPCD
Antarctic Oscillation's Significance for Prediction of Rainfall in May and June in Fujian
利用1979-2009年逐月NCEP/NCAR再分析资料和福建省66站降水资料,分析了3-4月南极涛动(AAO)的变化对后期福建前汛期(5-6月)降水的影响。结果表明:3-4月平均的AAO指数与福建前汛期降水有很好的正相关性,前期AAO偏强时,后期前汛期降水偏多,反之亦然;且AAO异常时降水的同号率为100%。对AAO异常年的分析发现,当前期AAO异常强时,后期北方冷空气活动频繁,南方暖湿气流输送强盛,在华南北部产生强烈锋生,导致福建前汛期降水偏…查看全部>>
Using the from 1979 March and to 2009, April on monthly NCEP/NCAR reanalysis data and the rainfall data from 66 stations in Fujian this paper analyzes the influences of the variation of Antarctic Oscillation (AAO) in the rainfall before the flood season (May and June) in Fujian. The results show thatthere flood versa. is a positive correlation between the March and April average AAO index and the rainfall before the season in Fujian. The stronger AAO index i…查看全部>>
