通过对瓦克环流、哈德莱环流、副热带高压、台风等的分析,结合广西降水和气温异常状况,认为厄尔尼诺现象发生时,赤道东太平洋海温异常升高,使瓦克环流和哈得莱环流发生变化,引起副热带高压增强,台风生成数减少,从而产生广西前汛期偏涝,后汛期偏旱,全年气温偏暖的结果。
通過對瓦剋環流、哈德萊環流、副熱帶高壓、檯風等的分析,結閤廣西降水和氣溫異常狀況,認為阨爾尼諾現象髮生時,赤道東太平洋海溫異常升高,使瓦剋環流和哈得萊環流髮生變化,引起副熱帶高壓增彊,檯風生成數減少,從而產生廣西前汛期偏澇,後汛期偏旱,全年氣溫偏暖的結果。

Through the analysis of Wacker circumfluence, Hadley cell, sub-tropical high pressure and typhoon, etc., and combining the abnormalities in precipitation and temperature in Guangxi, it is concluded that when El Nino occurs, marine temperature in the equator east Pacific rises abnormally, changing Wacker circumfluence and Hadley cell, strengthening the sub-tropical high pressure and reducing the generation of typhoon, which leads to the more flooded in early flood season and more drought in late flood season and the comparatively warmer climate in the whole year.
