广西四季降水气候特征分析

The Climatic Characteristics Analysis Of Precipitation In Four Seasons In Guangxi

运用正交经验函数展开方法对广西四季降水资料序列进行分解 ,根据各特征向量对各季降水的空间分布进行分型 ,然后逐年进行类型划分 ,并讨论了各种分布型的年际变化特征。结果表明 :全区性的降水偏多 (少 )是四季降水的主要类型。同时 ,各季的降水类型亦具有不同的分布特点和振荡特征。

The precipitation in four seasons in Guangxi is analyzed by using EOF. Based on the eigenvectors, the types of distribution of precipitation of each season and the type of each year are plotted out. The annual variation character of each distribution type is discussed. It shows that the precipitation above (below) normal level in the whole region is the main type of precipitation of each season. There are different distribution types and oscillation characters for each type of precipitation of each season.
