The Forcing of Divergent Wind and Transient Vorticity Fluxes to the Stationary Waves

Geng Quanzhen and Huang Ronghui (Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100080)  
The relationship of the convergence of transient vorticity fluxes and the vorticity sources generated by divergent wind, and their forcings to the upper troposphere stationary waves are studied with theoretical analysis, data diagnostics and barotropic model experiments. It is found that the convergences of transient vorticity fluxes tend to cancel or dissipate the vorticity sources generated by divergent wind. Both of these forcings are important to the maintenance of stationary waves. Meanwhile the roles of the divergences in different regions to the maintenance of stationary waves are also investigated. The results show that the convergence over mid latitude East Asia is important to the maintenance of East Asia trough. This convergence together with the strong divergence over Indonesia are the main forcings of the subtropical western Pacific anticyclone.
