然後用簡化方法分析了氣候平均經圈環流的季節變化,論文還對hadley環流的雙層結構和異常經圈環流的緯向差異以及elnino 、 lanina事件對局地經圈環流異常的影響作了研究,結果表明: 1 ,北、南半球hadley環流圈及其共同上升支的位置隨熱赤道作整體性移動, 7月最北, 1月最南。In the upper troposphere, there is no intact asian active center. the troposphere structure of summertime ao is implicated with the horizontal heterogeneity of air temperature throughout the whole troposphere with its center over asian continent, which results in the zonal asymmetry and baroclinic structure of the summertime ao ( especially its asian center ). on the contrary, the correlation between wintertime ao and sea - land thermal contrast confines in the lower troposphere, hence its zonal asymmetry and baroclinity in the lower level
夏季北極濤動的這種結構與對流層整層的溫度水平分佈不均勻性有密切聯系,且這種溫度分佈差異主要體現在亞洲大陸,因而也就使北極濤動的中緯度亞洲中心呈現出比同緯度帶其它區域更為明顯的緯向非對稱性和斜壓性;而冬季北極濤動受下墊面海陸分佈差異影響,其緯向非對稱型和斜壓性質主要出現在對流層中低層,在對流層高層表現出很強的環形模態和正壓結構。The most obvious feature of the first leading term of eof applied to the climatic vertically integrated water vapor flux over asian - australian monsoon region shows a planetary - scale southwesterly moisture transport, starting from south hemisphere, passing over asian monsoon region and flowing into north pacific, which indicates the interaction between the northern and southern hemisphere as well as between mid and low latitudes in the northern hemisphere
