    By using monthly meridional and zonal wind at grid point of 200hpa and 850hPa level in the global tropical ocean from 1973 to 1989, and at grid point of 10013, 850, 700, 500, 200, 100, 50hPa level from 1980 to 1989, in this paper, the higher and lower layer of troposphere (200, 850hPa) are considered climatically as air current passage across the equator, and the temporal and spatial variation characteristics of the strength for various air current passages across the equator are analyzed.
    本文主要利用1973~1989年逐月全球热带200hPa及850hPa层经、纬向格点风及1980年以来1000,850,700,500,200,100,50hPa各层经纬向格点风,确定了热带对流层高、低(200,850hPa)层具有气候意义的越赤道气流通道,并分析了各越赤道气流通道强度的时、空变化特征。

In this paper, the variations of the North Atlantic SST and it s influence on the Bohai Sea sea-ice in winter months are analysed. The affecting period is about nine months. It is also pointed out that the SST rhythm links the spring SST in the North Atlantic with the winter sea-ice of the Bohai Sea. This relationship may be explained as follows: Through rhythm activity the SST of the North Atlantic in winter repeats the main thermal characteristics formed in spring. Then, the winter SST exerts a deep influence...

In this paper, the variations of the North Atlantic SST and it s influence on the Bohai Sea sea-ice in winter months are analysed. The affecting period is about nine months. It is also pointed out that the SST rhythm links the spring SST in the North Atlantic with the winter sea-ice of the Bohai Sea. This relationship may be explained as follows: Through rhythm activity the SST of the North Atlantic in winter repeats the main thermal characteristics formed in spring. Then, the winter SST exerts a deep influence on the simultaneous circulation over the ocean by heating the atmosphere. Finally, under the active interactions between air currents in the different parts of the earth the influence of SST can propagate in the atmosphere from the North Atlantic to East Asia. Therefore, the SST rhythm should be thought to link the spring SST in the North Atlantic with the winter sea-ice in the Bohai Sea.

本文分析了北大西洋表层海温对冬季渤海海冰的影响,其影响时间为9个月左右。同时,指出了海温的韵律造成了北大西洋春季海温与冬季渤海海冰之间的关系,这个关系可做如下解释:北大西洋海温通过韵律活动在冬季出现与春季类似的热力特征。冬季的海温加热大气,从而影响冬季的大气环流。最后,通过不同地区之间的海气相互作用,海温的影响从北大西洋传到东亚。所以,应该认为是海温韵律造成了北大西洋春季海温与渤海冬季海冰之间的关系。

According to the analysis of surface meteorological data of eleven meteorological stations in the area of Hangzhou Bay, three stations (Jinshanzhui, Zhenghai and Hangzhou) are selected in further analysis.

According to the analysis of surface meteorological data of eleven meteorological stations in the area of Hangzhou Bay, three stations (Jinshanzhui, Zhenghai and Hangzhou) are selected in further analysis. Basic statistics of main meteorological elements such as wind, temperature, precipition, humidity, fog and typhoon of these stations arc used to represent the general climatological features in this area. Due to the effect of monsoon the wind direction presents monsoon feature. The wind velocity is greater at the mouth than at the lop of the bay. Because of adjustment of the oceanic air current. The temperature is a little lower at the mouth than at the lop in summer and higher in winter. The humidity of the air is relativity large all the year round. Annual precipitation is usually over 1000 mm and concentrated in the period of March-September.

本文对杭州湾地区十一个气象台站的地面气象资料作了对比分析,选取金山嘴(湾口北)、杭州(湾顶)、镇海(湾口南)三站作为代表站,对风,气温,降水,湿度,雾,台风等几个主要气象要素进行了统计分析,得到了杭州湾地区的一般气候特征。本区受季风影响,风向主要表现为季风特征,风速湾口大于湾顶。气温受海洋气流的调节,夏季湾口气温稍低于湾顶,而冬季呈现出高于湾顶的趋势。全年空气比较湿润,多雨,年降水量几乎都在1000.0毫米以上,主要集中在3—9月。

The paper analyses the hydro-meteorological data obtained from equatorial western Pacific in October, 1987. During the period of this investigation, the currents of the area investigated interacted intensively, each element changed obviously with the transformation of the convection weather and the prevailing air current. The horizontal distribution characteristics showed balanced between north and south. The sea and air temperature showed high in the east and low in the west. The mean daily* variation and space-time distribution regularities were good. The variation of sea-air heat status was small. The variation feaures of temperature and humidity and the transformation time of seasonal wind current were different from those of the adjacent sea. EININO event directly affected the meteorological characteristics during the period of the investigation.
