其强灾害的产生与热带气旋登陆时能量短时内的突然释放及台风中强烈的中尺度扰动特征有很大关系。
Those serious disasters of tropical cyclones are closely related to sudden release of energy and mesoscale disturbances of a landing tropical cyclone in a short time.
结果在速度剪切度增大到一定程度时，将会出现小尺度扰动的混沌行为，它导致局部高剪切区中湍斑的产生。
Results as the velocity shear increases to a certain extent, the small scale disturbances will exhibit chaotic behavior, which leads to the production of turbulent spots in local high shear regions.
基流二次切变对于中尺度对称扰动来说是一个不稳定因子，并且驱动不稳定的中尺度对称扰动在南北方向传播；
The second-order shear of the basic flow represents an instable factor for the symmetric disturbance, and drives the unstable mesoscale disturbance to travel in the meridional direction;
