季风环流 meaning in English
monsoon circulation
Examples
- Its interannual variation ' s main period is about 4 ~ 5a and the 7 ~ 8a ' s period exist too ; the interdecadal variation ' s main period of the australian high is about 15a . the interannual variation of australian high ( aah ) has correct correlation with antarctic oscillation and enso , and the enso ' s 4a period has the most important influence on the aah . ( 2 ) when the ah becomes stronger , the members of the whole aamcs are stronger following it . that is to say , in the years that the ah is stronger ( compared to the weak years of ah ) and on the horizontal circulation , the members of aamcs , including the ah , the cross - equator flow ( cef ) between 100 and 160 e , the south china sea south - west monsoom ( ssm ) , the south sea monsoon rough , the tropical easily flow , subtropical high ( sh ) , the mei - yu front , the mid - latitude effect , become stronger , and their positions are more southward ; in the meridional - right circulation , there are five circulations including classic monsoon meridional - cirle circulation and hadley circulation that become stronger in the strong years of ah than in the weak years of ah
本文采用ncep ncar再分析月平均的全球海平面气压场、高度场、海表温度场、高云量和cmap全球降水资料,以及中国160站逐月降水资料,分析了1948 2002年期间澳大利亚高压(以下简称澳高)的年际和年代际变化以及澳高年际变化对亚澳季风环流系统的影响,结果显示: ( 1 )澳高存在明显的年际和年代际变化,澳高年际变化以4 5年的周期变化为主,同时兼有7 8年左右的周期,而澳高的年代际变化则以15年左右的周期变化为主:澳高年际变化同时与南极涛动和enso有正相关,并且enso的4年左右的周期变化对澳高年际变化影响最大。 - In drought or flood years over the yangtze river basin , the features of the establishment , progression and decrease of moisture transport is significantly different , meanwhile the differences of the moisture transport by the monsoon circulation between mid and low latitudes in the northern hemisphere , and by the subtropical high are obvious , so are their convergence , especially over south china sea , the tropical west pacific , the yangtze river basin , north china and north - east in china
( 4 )长江流域旱涝年亚澳季风区夏季风水汽输送的建立、推进、减弱的阶段性特征显著不同,对应的中低纬季风环流、副高环流等季风系统水汽输送、汇合也有显著差别,尤其是在南海、热带西太平洋、长江流域、华北和东北等地区。 - The summer rainfall anomaly of north china is closely related to indian low , west pacific subtropical high , westerly troughs and ridges in mid - latitude , south asia high , subtropical monsoon circulation and cold air activity on the corresponding period , and similar circulation pattern also appears in the preceding spring
结果表明: ( 1 )华北夏季降水异常与同期印度低压、西太平洋副高、中纬度西风槽脊、南亚高压、副热带季风环流和冷空气活动的异常都密切相关。华北夏季降水异常年春季的环流特征与夏季类似。 - The responses of asian monsoon circulation to the heat source annual anomalies over the bay of bengal and philippines in summer and the annual relationships between the heat sources over the bay of bengal and philippines and the precipitation of china in summer are studied emphatically , with the results as follows : ( 1 ) the coverage and intensity of atmospheric heat source are the largest and strongest in summer and then turn smaller and weaker in autumn and winter , and in turn begin to become larger and stronger in spring again
着重讨论了夏季孟加拉湾和菲律宾热源年际异常时,亚洲季风环流系统的响应,及其与中国夏季降水的年际关系。结果表明: ( 1 )夏季大气热源的范围最大,强度最强,以后以秋、冬季依次变小变弱,春季又开始变大变强。夏季亚洲季风区有三个强的大气热源中心,其中以孟加拉湾热源最强,菲律宾热源和印度半岛西部热源次之。 - 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,热带太平洋的walker环流和热带印度洋的纬向季风环流在海洋性大陆附近耦合,当elnino事件发生时,太平洋的西风异常可以通过这两个纬向的垂直环流与印度洋的东风异常联系起来,而1976 1977年以后,由于西太平洋walker环流上升支东移到澳大利亚北部,热带两洋的纬向垂直环流无法耦合,热带太平洋elnino事件中的西风异常与热带印度洋的东风异常联系减弱,所以1976 1977年以后, enso在热带印度洋的信号减弱了。
