摘要
对华南前汛期中的前期锋面降水(4月)和后期季风降水(6月)分别作EOF分析,发现其降水分布存在以下特征:无论是锋面降水还是季风降水,前四个特征向量所代表的基本雨型分布都为全区一致型,东西反相型,南北反相型以及东中西分布型。锋面降水这四种雨型所占的比重从大到小是:全区一致型,东西反相型,东中西型,南北反相型;季风降水四种雨型所占比重从大到小则为:全区一致型,南北反相型,东西反相型,东中西型。
The EOF analysis is used to explore the characteristics of frontal rainfall in April and summer monsoon rainfall in June, the results indicate that both the frontal rainfall and summer monsoon rainfall during prerainy season in South China have four important spatial patterns, including the whole region distribution, the east-west distribution, the south-north distribution, and the east-middle-west distribution. The sequence of specific gravity form large to small is the whole region distribution, the east-west distribution, the east-middle-west distribution, the south-north distribution in the frontal rainfall, and the whole region distribution, the south- north distribution, the east-west distribution, the east-middle-west distribution in the summer monsoon rainfall.
