地面中尺度能量锋对强对流天气作用的数值模拟研究

NUMERICAL STUDY OF EFFECT OF SURFACT MESO-SCALE ENERGY FRONT ON SEVERE CONVECTION WEATHER

本文基于地面中尺度能量锋对强对流天气影响的事实,利用二维中尺度湿空气动力模式,进行数值模拟研究,结果指出:在中尺度能量锋的高能一侧引起扰动涡旋,在涡旋的,上升支气流部位可对强对流天气产生一定影响。

In this paper according to the fact that the surface meso-scale energy front have an effect on severe convection, the author set up a numerical simulation using two dimen ional meso-scale moist air dynamic model. According to the result the author pointed out that di turbance eddy is to be produced by the side of high energy of the meso-scale energy front. The zone of upward current of eddy may have some effect on severe convection weather.
