  tropical easterly
The results show that the radiative transfer is essential in maintaining the intensity of the low level Somali Jet as well as the upper level Tropical Easterly Jet (TEJ) over the Indian sub-continent and adjoining seas.
      
These high winds have been found as a unique phenomenon distinct from a jet stream and therefore it is considered appropriate to call them Tropical Strong Easterlies (TSE) rather than as a tropical easterly jet stream.
      
On finding these current concepts questionable, this study offers an alternative explanation for the migration of the upper tropospheric anticyclone to the Tibetan Plateau and also for the development of the tropical easterly jet.
      
This paper, however, assesses the role of an upper troposphere synoptic feature of importance in modulating surface rainfall over Sudan in the eastern Sahel: the Tropical easterly Jet (TEJ).

The FGGE Ⅲ-b data compiled by ECMWF of the July 1979 is used to diagnose the kinetic energy (KE) budget of the tropical flow. The results reveal that the horizontal distribution of the mean flow KE is very similar to that of mean KE. This similarity indicates that the major features of the tropical summer circulation are standing eddy phenomenas. The transient KE formed two hemispheric interaction channels near 105°E and 150°E at 850 hPa and near 150°E and 30°W at 200 hPa. Also, large value transient KE occurred...

The FGGE Ⅲ-b data compiled by ECMWF of the July 1979 is used to diagnose the kinetic energy (KE) budget of the tropical flow. The results reveal that the horizontal distribution of the mean flow KE is very similar to that of mean KE. This similarity indicates that the major features of the tropical summer circulation are standing eddy phenomenas. The transient KE formed two hemispheric interaction channels near 105°E and 150°E at 850 hPa and near 150°E and 30°W at 200 hPa. Also, large value transient KE occurred over the mid-ocean trough areas, the so called "storm track".At 850 hPa, Somali jet is the main circulation system which generates KE. At 200 hPa, the generation is positive (negative) in the upstream (downstream) region of the tropical easterly jet. It indicates that the kinetic energetics of the easterly jet is similar to that of the westerly jet in the mid-latitude.In the Afirica-Arabian Sea monsoon region, the net generation of KE (KE generation plus KE flux divergence) is negative in the upper troposphere. While in the Bay of Bangel-South China Sea region the net generation is negative in the lower troposphere. Such deficiencies of KE may be compenseted by the vertical transport of KE, i. e., the vertical coupling of the upper and lower tropospheric flow is quite important in the monsoon area.

应用欧洲中期预报中心的FGGEⅢ-b个客观分析资料计算了1979年7月热带大气的动能平衡。热带环流系统的动能主要集中在定常涡旋部分。对流层下层,105°E和150°E为两半球间瞬变涡旋的通道。对流层上层,瞬变涡旋的通道和洋中槽相联系,位于150°E和30°W附近。 索马里急流是对流层下层制造动能的主要环流系统。对流层上层,南亚东风急流入口区制造动能,出口区破坏动能,其动能收支与中纬度西风急流相似。 非洲-阿拉伯海季风区和孟加拉湾—南海季风区的动能平衡很不相同。动能的垂直输送可能在季风环流中很重要。

In this paper, the struoture of the tropical easterly jet is analysed by using FGGEⅢB data. The investigation of angular momentm budget shows that the divergence of the horizontal momentum flux in the high troposphere affected by the mean meridional monsoon circulation is a dynamic factor in maintaining the easterly jet. The jet is closely related to the mean maridional tempereture gradient. The tempereture gradient in the middle high troposphere is affected by the heating field. Therefore, the heating...

Therefore, the heating caused by the monsoon trough and ITCZ is an important thermodynamical factor affecting the intensity of the jet.
