The establishment of a blocking anticyclone in the mid-higher latitude, the strong and the stable westerly jet in the middle latitude and the abnormal actively convective in the tropical region are conducive to the relative stability of the WPSA.

中高纬度阻塞高压双阻型的建立、强劲而稳定少动的中纬度西风急流以及热带异常活跃的对流，均有利于副热带高压的相对稳定；

The convective of the hail region developed higher than that of normal thunder region and the instability energy is greater.

降雹区与普通雷暴区相比，降雹区的不稳定能量更大，对流运动伸展得较高。

The results show that the reduction in wind speed near the convective region in upper levels and passage through the rainfall center of the intensifying LLJ played crucial role in the event.

The residual effects of the cloud clusters are generally ignored even though the area they cover is perhaps an order of magnitude larger than the convective region itself.

云团的残余影响通常是忽略不计的，即使它们覆盖的地区比对流区本身可能大一个量级也如此。

The most frequent convective region over the Plateau is centered at 30 ° N, 90 ° E, not in the eastern Plateau.

高原上最频繁的对流区在以30°N，90°E为中心的地区，而不在高原东部，而且喇叭口形的雅鲁藏布江出口区是一个小值区。

However, there is almost no convective rain in winter in northern China, so the effect of cumulus precipitation to the grid scale can be disregarded. Therefore the grid scale precipitation is primary in winter of northern China.

冬季，中国北方大陆基本没有对流降水产生，不同积云对流方案对网格尺度降水预报的影响基本可以不予考虑，中国北方的冬季降水主要是由网格尺度降水构成的。

On a seasonal scale, the results indicate that the rainfall ratio of stratiform rain to deep convective rain is proportional to their rainfall pixel ratio.
