| 摘 要： | 在无基本气流的假定下，应用无辐数正压模式研究双台风相互作用的物理机制。台风Ａ位于观风Ｂ以西，两台风相距６０ｋｍ，且具有相同的强度。在台风Ａ（台风Ｂ）的非对称流场中，由台风Ａ（台风Ｂ）的线性β效应产生的非对称涡旋的方位相位与由台风Ｂ（台风Ａ）形成的非对称涡旋方位相位相反（相同）。因此，台风Ａ（台风Ｂ）的大尺度非对称涡旋较弱（较强）。小尺度涡旋逆时针旋转导致台风Ａ逆时将打转。稳定的偏南非对称气流使台风

| Abstract: | The physical mechanism of interaction of binary typhoons with the same intensity is investigated in terms of a nondivergent barotropic model with no basic flow.The typhoon A is situated to the west of typhoon B. The two typhoons are 600 km apart, and have the same intensity. In the asymmetric flow field of typhoon A(typhoon B),the azimuthal phase of asymmetric gyres due to the linear beta effect is opposite to (the same with) that of asymmetric gyres due to typhoon B (typhoon A). Therefore, the large scale asymmetric gyres of typhoon A(typhoon B) is weaker (stronger). The counterclockwise rotation of the small scale gyres leads to typhoon A to loop counterclockwise. The steady southerly asymmetric flow causes typhoon B to move toward the north. |
