Abstract:
Firstly,variations of the total energy and its compositions at the central area of the lan- ded Typhoon 9608,which belongs to the pattern of the interaction between Typhoon and westerly trough,have been analysed．The results show that as a result of the latent heat en ergy increase,the total energy increased once again．But the increase of the latent heat energy was closely related to the low level jet of east by south wind on the east side of the Typhoo．And,within the east-north quadrant of the Typhoon the latent heat energy increaseed vigorously,and there is the maximum rainfall area as well．Secondly,using the arrangements between the divergent wind field and the rotation wind field at upper level of the troposphere,and the conversion relation between the kinetic energies of the divergent wind and the rotation wind,the variation tendency for maintaining the upper level anticyclonic circulation located on the east of Typhoon and over Bohai Sea-Japanese sea has been estimated by eyes．The divergent wind flowed from upper level over the depression area was advantageous to maintain and strengthen the upper anticyclonic circulation．Finally,the east-west vertical circulation scheme of the pattern of the interaction between Typhoon and westerly trough is given．
