Lots of actual detective data prove that cold or thermal advection often overlap with macroscale convergence or divergence, this kind of Doppler radial velocity character of recombination wind field is analyzed by numerical simulating in the paper, meanwhile the influence by raindrop dropping velocity is analyzed as well, the value of convergence or divergence in each latitude can be gotten quantitatively from radar PPI pictures according to these figures of divergence change which get by numerical simulating.
