Furthermore, intensity changes of westerlytrough would directly lead to intensity changes of mesoscale systems and thus lead to different rainfall.
台风及西风槽强度的改变将直接导致中尺度系统强度的变化，从而造成降水强度的不同。

After storm's entering westerlytrough, the subtropical cyclone's reintensification was related to the high potential vortex's downward transmission from stratosphere.
风暴完全并入西风槽后，变性后的温带气旋再次加强与平流层高位涡的向下输送有关。

The contribution of various weather systems to precipitation varies in different seasons, and the rainfall and the number of rainy days induced by the westerlytrough are the greatest.
