In this paper,an analysis is made on the structure of the July meanflow field at 850 mb,700 mb,500 mb over the continent of Asia during theyear 1951—1955 and the mean contours at 200 mb over Asia for July andAugust,1956.The vertical cross-sections of the mean flow and temperaturefields along 75°E,90°E,105°E and 120°E for July and August,1956 havebeen constructed.The three-dimensional flow structure over continent ofAsia is constituted of the following three basic currents:(1) the westerliesof middle latitudes,(2)...

In this paper,an analysis is made on the structure of the July meanflow field at 850 mb,700 mb,500 mb over the continent of Asia during theyear 1951—1955 and the mean contours at 200 mb over Asia for July andAugust,1956.The vertical cross-sections of the mean flow and temperaturefields along 75°E,90°E,105°E and 120°E for July and August,1956 havebeen constructed.The three-dimensional flow structure over continent ofAsia is constituted of the following three basic currents:(1) the westerliesof middle latitudes,(2) the upper level tropical and subtropical esterlies,and (3) the south-westerly monsoon under the upper level tropical andsubtropical easterlies.Moreover,the changes of the general circulation over Asia in thetransitional period between spring and summer,1956 is also investigated.It is found that a leaping change of the general circulation over Asiaoccurs during this period.The upper level subtropical ridge was establis-hed over the latitude of Tibet,and over south Asia (to the south of 12°N)an high level easterly jet-stream was established.At the same time,thesouth-westerly monsoon of India and the “Meiyu” (plum rain) season ofthe Yangtze valley set in.The authors also found that the northwarddisplacement of the rain belt is closely related to the northward retreatand the accompanying weakening in intensity of the westerlies over Chinamain land.

作者分析了1951—55时期中850、700及500毫巴的7月平均气流场的构造,以及1956年7、8两月亚洲上空200毫巴平均等高线图.又作了1956年7、8两月东经75度、90度、105度和120度经线上平均风场和温度场的剖面.我们发现,在夏季有三种基本气流组成亚洲大陆上空三度空间的气流场:即,(1)中纬度的西风气流,(2)高空热带和副热带的东风气流,(3)位于高空热带和副热带东风气流下面的西南季风.此外,对于1956年从春季到夏季的过渡时期中,亚洲上空大气环流的转变,亦作了研究.我们发现,从春季到夏季的过渡时期中,亚洲上空的大气环流有着一个跳躍的转变.在这个时期中,喜马拉雅山南边的高空副热带西风急流向北撤退,在西藏高原的纬度上空,建立一个副热带高压脊线,并且在亚洲南部上空(北纬12度以南)建立一支高空东空急流.同时印度的西南季风和我国长江流域的梅雨时期开始出现.作者又发现,夏季在中国大陆上,雨带的北移和西风带北撤以及相应的西风带强度的削弱有着密切的联系.

Based on wind data at 200 mb over Tateno,Japan,for June—august,1950—1956.We discussed the variation of wind field during the last stageof Mai-yü in eastern Asia.It is found that the northward displacement ofwesterly Jet stream and the appearrance of easterly wind is a good indexof the end of Mai-yü period and the beginning of prevailing summer sea-son.Besides,the 5-days mean cross sections of zonal wind along 140°Efor the period of June and July,1954—1956 are constructed.From themwe further found that...

Based on wind data at 200 mb over Tateno,Japan,for June—august,1950—1956.We discussed the variation of wind field during the last stageof Mai-yü in eastern Asia.It is found that the northward displacement ofwesterly Jet stream and the appearrance of easterly wind is a good indexof the end of Mai-yü period and the beginning of prevailing summer sea-son.Besides,the 5-days mean cross sections of zonal wind along 140°Efor the period of June and July,1954—1956 are constructed.From themwe further found that during the last stage of Mai-yü,with the northwardretreat of the upper westerlies over Japan,the subtropical ridge apparantlyshifts northward and the typhoons which were limited to the south westernpart of the Paciffic now begin to invade East sea and Yellow sea one byone.These facts are probably helpful to predication.

根据1950—1956年6—8月日本馆野站上空200毫巴的每天测风材料,定出在东亚梅雨结束期的风向、风速转变的奇异性.我们发现馆野上空西风急流的消失和东风的出现,是东亚梅雨结束和盛夏开始时期的一个良好的标记.另外,又作了1954—1956年东经140度各年6—7月每5天平均东西风风速剖面图.我们发现在东亚梅雨结束时期,日本上空的高空西风北撤,太平洋副热带高压脊显著北伸,并且西南太平洋上的颱风便一个接一个侵入东海黄海.这种特徵各年都是相似的,因此可能有一定的预告价值.

Using the climatological data and aerological reports of the years 1951—1957,the author investigates the characteristics of Climate of May-Yü inFar East and its relation to the behaviour of circulation over Asia.It isfound that May-Yü occurs in the transitional period from spring to summer.The onset of May-Yü is associated with the outburst of Indian Monsoon.They are closely related with the dissolution of the jet stream to the south ofHimalaya.When the jet stream over Japan disappears and easterly wind...

Using the climatological data and aerological reports of the years 1951—1957,the author investigates the characteristics of Climate of May-Yü inFar East and its relation to the behaviour of circulation over Asia.It isfound that May-Yü occurs in the transitional period from spring to summer.The onset of May-Yü is associated with the outburst of Indian Monsoon.They are closely related with the dissolution of the jet stream to the south ofHimalaya.When the jet stream over Japan disappears and easterly wind be-gins to appear,the May-Yü period terminates.The change takes place inthe same manner each year.The results are helpful to prediction.

本文根据气候的资料以及1951—1957年的高空资料,对东亚的梅雨期气候特点,以及梅雨期跟亚洲上空大气环流季节变化的关系,作了分析.作者发现,东亚梅雨期的开始和结束是很有规律性的,梅雨期与亚洲上空大气环流的季节变化有着很密切的关系.这个时期是发生在亚洲上空行星风带向北突然推进的时期.东亚梅雨期开始的日期跟印度季风在印度加尔各答建立的日期是相一致的.梅雨期的结束跟日本馆野高空西风急流消失并且东风出现的日期很接近.这种在亚洲上空出现的大气环流季节变化,在年与年之间,虽然在时间上有一些出入,但变化的型式却是一致的.这种现象的揭露,对于东亚梅雨的了解及预报问题是有帮助的.
