从GCM模式预测结果获取区域尺度特征的气候变化的统计方法被称为Downscaling方法,它主要是通过区域气候尺度的预报量与GCM模式输出或大尺度地面观测资料建立统计模式.在建立模式之初,研究各种尺度资料的匹配是至关重要的问题.本文在不同的站点数量、区域网格分辨率和差值影响半径的条件下,对资料处理方法的可行性和结果的可靠性作了分析探讨.结果说明:一个大尺度网格箱内用20个站点资料代替40个站点的资料是可行的,并且确定了最佳插值方案:当次网格分辨率取1°×1°时,插值影响半径应取1;当次网格分辨率取0.5°×0.5°时,插值影响半径应取为2.本文还对温度场、降水场及其对应的EOF场进行了比较试验;并做了温度场、降水场与同步海平面气压场(SLP)的单点线性相关分析.
