Abstract: In this paper the influence of velocity profile and heating source profile on the initiation and development of typhoon has been tested by using the 5-layer primitive equation model in cylindrical coordinates. Assuming constant heating source, it is found that in upper layer the anticyclone is the result of the development of typhoon. The perpendicular shear of initial wind field is disadvantageous to the development of typhoon. Development of typhoon is related to perpendicular distribution of the heating source. It is advantageous to the development of typhoon if the heating source in upper layer is stronger than in lower layer.
