摘要:
基于江苏省60个气象站52年月降水量和月平均气温资料,计算了站点多时间尺度标准化降水蒸散指数(SPEI),并利用经验正交函数分解(EOF)、旋转经验正交函数分解(REOF)、统计检验聚类(CAST)等多种空间分型法对SPEI场的空间结构进行分析。结果表明:江苏省干旱主要表现为全省一致型、南北反向型和南北波列型3个空间型,江苏全省自北向南可分为4个干旱区。
Abstract:
Based on monthly total precipitation and average air temperature series of 52 years from 60 meteorological stations across Jiangsu Province, the Standardized Precipitation Evapotranspiration Index(SPEI)at multiple time scales was calculated for each station. The Empirical Orthogonal Function(EOF), Rotated Empirical Orthogonal Function(REOF)and Cluster Analysis with Statistical Test(CAST)methods were introduced to identify the spatial characteristics of the SPEI fields. The results showed that the drought in Jiangsu Province had three representative spatial patterns, the consistent pattern in whole province, the opposite pattern of south to north and the wave pattern of south to north. Therefore, Jiangsu Province could be divided into four drought regions from north to south.
