wind circulation
Examples
- With 1958 ~ 1997 ncep / ncar reanalysis data and 1961 ~ 1995 summer ( jja ) rainfall and temperature records of 160 stations in china , a new east asian subtropical summer monsoon circulation index is defined , in which the barotropic and baroclinic components of the circulation are included
摘要采用大气环流正、斜压分解方法，从东亚副热带夏季风为正、斜压混合型季风观点出发，定义并计算了1958 - 1997年东亚副热带夏季风环流指数。 - ( 2 ) there is stage of soil formation from the evolution of pedogenic environment in the weihe valley during holocene . soil formation shows the law of evolving from warm and wet strong soil formation period to cold and dry dust deposition period ( weak soil formation period ) and to warm and wet strong soil formation period again . the loess - soil sequence is a compound soil sectional system of different kinds of soil evolution under different bio - environment and pedogenic processes
（ 2 ）通过对全新世渭河流域成壤环境演变问题的讨论，揭示了全新世渭河流域土壤的发育具有阶段性，表现为由温湿的强成壤期向冷干的沉积期（弱成壤期）演变、再向温湿的强成壤期演变的规律；黄土一古土壤序列是不同生物气候环境下、不同成壤过程发育的不同土壤类型演替而形成的复合型土壤剖面体系；而且由于冬夏季风环流及其环境效应在空间上的差异，使得复合型土壤剖面体系也存在着南北差异。 - In the second part of the paper , with employing the game reanalysis data and on the basis of the theories of the baroclinic vorticity development , this paper inferred from the dynamic analysis that the horizontal vorticity can represent the baroclinic intensity of the large - scale atmosphere , and the conversion of the horizontal vorticity converting into the vertical vorticity is actually the phenomenon that the horizontal vorticity flux of the summer monsoon owning the striking longitudinal - direction vertical structure and the strong baroclinicity , influence on the horizontal movement of the atmosphere
在第二部分，基于第一部分的结果，本文在斜压涡度发展理论的基础上，用在我国季风区具有更高准确性的game再分析资料，讨论分析了能代表大尺度大气斜压性强度的水平涡度在向垂直涡度转化的情况，说明了此转化就是具有明显经向垂直结构特征和强斜压性的夏季风环流圈将其经向垂直剖面上的涡旋通量强迫于水平运动的现象。 - ( 4 ) based on the ncar ccm3 simulations , the influence of the previously winter kuroshio ssta on the easm is investigated . results from the simulations are highly coincidence with the observations , namely , the winter kuroshio ssta may impacts the subsequent year east china summer rainfall by making influencing on the strength and location of the west - northern pacific high and the easm systems
( 4 )利用ncarccm3模式模拟冬季黑潮区域海温异常对东亚夏季风的影响，模式模拟的结果与统计分析结果是一致的，即前期冬季黑潮区域海温异常可以通过影响次年夏季的西太平洋副热带高压的强度和位置变化以及东亚夏季风环流的强弱，从而进一步影响我国东部地区的降水，尤其是长江中下游地区。 - ( 4 ) in summer , tropic west pacific ssta decadal change infect precipitation decadal change in south and north of changjiang river maybe by : positive ssta in tropic west pacific weaken the summer monsoon circulation , lead more precipitation in south of changjiang river and less precipitation in north of it , vice versa ; middle north pacific ssta decadal change infect precipitation decadal change in mid - down valley of changjiang river maybe by : when ssta is negative in middle north pacific , the height field in tropic rises obviously , the subtropical high strengthens and extends westward , the northern limit retreats southward , leads upper trough retreats northward and move eastward , meiyu front moves northward , then leads more precipitation in mid - down valley of changjiang river , vice versa ; middle northwest pacific - low latitude mid - east pacific infects precipitation in north china possibly by change the activity of northeast china cyclone
（ 4 ）热带西太平洋ssta年代际变化影响夏季中国长江南北降水年代际变化的可能机制是热带西太平洋海表温度正（负）异常减弱（加强）东亚夏季风环流，从而使江南降水增加（减少） ，江北降水减少（增加） ；夏季中部北太平洋ssta年代际变化影响中国长江中下游地区夏季降水年代际变化的可能机制是中部北太平洋海表温度负异常，将导致热带地区高度场普遍增高，副高加强西伸，副高北界南退，致使高空槽北缩东移，梅雨锋西移北进，中国长江游中游、中卜游降水增多，反之亦反；夏季中高纬西北太平洋一低纬中东太平洋反向距平分布结构影响中国东北降水的可能机制是低纬中东太平洋海表温为负异常。
