螺旋雨带

结果表明：AMSU资料作为一种新的卫星微波探测资料，在热带气旋的结构、螺旋雨带的强度及其降水强度的分析预报中具有一定的应用价值。

As a result , as a new kind of satellite soundings , AMSU microwave data are of some utility in analyzing and forecasting the structure of tropical cyclones , and intensity of a spiral rainband and rainfall .

涡旋Rossby波说和重力惯性波说仍然是螺旋雨带形成理论的两种不同观点；

Vortex Rossby waves theory and inertia-gravity waves theory are the two main different viewpoints about the formation of spiral rain bands ;
