| 摘 要： | 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

| Abstract: | 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. |
