摘　　要：采用无基本气流的无辐散正压模式模拟了双热带气旋的运动。应用非对称理论研究了双热带气旋的相互作用。双热带气旋中的每个热带气旋主要由通过其中心的非对称气流（即通风气流）作用而移动。这股非对称气流是由其自身的线性和非线性效应产生的非对称涡旋与其配对热带气旋形成的非对称涡旋相叠加而引起的。The motion of binary tropical cyclones is numerically simulated using a nondivergent,barotropic model with no basic flow.The interaction of binary tropical cyclones is investigated applying the asymmetric theory.Each of binary tropical cyclones will mainly be displaced by the asymmetric flow passing its centre(i.e.the ventilation flow).This asymmetric flow is induced by the superposition of the asymmetric gyres created by the linear and nonlinear effects itself and the asymmetric vortex formed by its counterpart tropical cyclone.
