| 摘 要： | A non-dimensional secondary circulation equation for typhoons has been derived and then 11-yr com-positing typhoon data were used to estimate the thermally forced secondary circulation.The main resultshave been obtained as follows:(1)The diabatic heating and Cu vertical heat mixing are major thermal forcing factors.They have thesame magnitude of order.(2)The effects of eddy flux and Cu horizontal mixing of heat are of minor im-portance.(3)Ekman pumping and Cu vertical heat mixing cooperatively work.This feedback process isfavorable for the enhancement of the secondary circulation of typhoons.

| Abstract: | A non-dimensional secondary circulation equation for typhoons has been derived and then 11-yr compositing typhoon data were used to estimate the thermally forced secondary circulation.The main results have been obtained as follows:(1)The diabatic heating and Cu vertical heat mixing are major thermal forcing factors.They have the same magnitude of order.(2)The effects of eddy flux and Cu horizontal mixing of heat are of minor importance.(3)Ekman pumping and Cu vertical heat mixing cooperatively work.This feedback process is favorable for the enhancement of the secondary circulation of typhoons. |
