4 )梅雨期長江中下游降水多寡與前期4 、 5月南半球環流存在聯系,當4 、 5月南太平洋中高緯度地區經向環流較為明顯,南極渦偏強時,長江中下游地區梅雨期降水易偏多;反之,當4 、 5月南太平洋中高緯度地區緯向氣流較為明顯,高緯度西風較弱,南極渦偏弱時,長江中下游地區梅雨期降水易偏少。During 1950 ~ 1976 / 1977, the walker circulation over the tropical pacific and the vertical zonal monsoon circulation over the tropical indian ocean coupled at the oceanic continent, the same period when el nino occurs, the anomaly of the west wind over the tropical pacific can correlate with the departure of east wind over the tropical indian ocean through the two coupled vertical zonal circulation. but after 1976 / 1977, the updraft of the walker circulation moved eastward. locating at the north of australia. therefore the two vertical zonal circulation could n ' t coupled, and the anomaly of west wind and the departure of east wind could n ' t geared. in the result. the signal of enso decreased in indian ocean after 1976 / 1977
1951 1976 1977年,熱帶太平洋的walker環流和熱帶印度洋的緯向季風環流在海洋性大陸附近耦合,當elnino事件發生時,太平洋的西風異常可以通過這兩個緯向的垂直環流與印度洋的東風異常聯系起來,而1976 1977年以後,由於西太平洋walker環流上升支東移到澳大利亞北部,熱帶兩洋的緯向垂直環流無法耦合,熱帶太平洋elnino事件中的西風異常與熱帶印度洋的東風異常聯系減弱,所以1976 1977年以後, enso在熱帶印度洋的信號減弱了。分享友人
