摘    要:分析了与韩国雨季开始和结束的年际变化相关联的一些要素场发生的变化。分别对雨季开始和结束早晚的个例进行了合成分析。6月月平均资料用来分析与雨季开始早晚相关联的要素场变化,而在分析与雨季结束早晚相关联的要素场变化时则利用7月月平均资料。结果表明,对应雨季开始(或结束)早晚,大气环流和表面温度等要素不仅在东亚地区、而且在远离东亚的地方具有显著的差异。在东亚地区的显著差异主要是高空急流和西太平佯副热带高压。远离东亚的显著差异主要是印度季风和ENSO现象。印度季风与韩国雨季开始和结束均有关联,但ENSO现象只与雨季开始显著相关、而与结束并没有显著的关联。

关 键 词:韩国雨季  雨季开始  雨季结束  年际变化  关联场

Abstract:The associations of onset and withdrawal of the rainy season in South Korea (called Changma) have been examined. Composite studies showed that there are significant differences in circulations between extremely early and late onset (or withdrawals) not only over East Asia, but also over remote areas. The in situ significant differences include the upper-level jet over East Asia and the subtropical anticyclone over the western North Pacific at lower levels. The significant remote associations include the Indian monsoon and ENSO. The Indian summer monsoon is related to both onset and withdrawal of the Changma, while ENSO has a significant relation only to onset, but not to withdrawal.
Keywords:Changma  Onset  Withdrawal  Interannual variation  Association
