降雨分布特性の気象力学的解析

Abstract

The orographically induced inflow pattern of the lower water vapor and thetime averaged rainfall distribution were represented by the numerical analysis basedon the mesoscale dynamic model, in the case of heavy rainfall which arose alongthe Baiu-Front around the Kinki District in Japan.From the analysis, we can verify that the heteorogenity of lower wind field inmeso-B scale arose under the characteristics of the synoptic scale condition and theconfigulation of the ground and therefore the inflow pattern is stable, and that theinflow pattern has great influence of the determination of heavy rainfall area.From above, we can conclude that the heteoroginity of inflow pattern of lowerwater vapor in meso-B scale is very useful for the meteorologicaly based short-termrainfall prediction.
