About the heavy rain which brought great damage to Hiroshima prefecture in June 1999, various studies have been made. But, the cause of its heavy rain has not been examined from meteorological viewpoint. Since generation of the heavy rain is considered to originate in the overall weather condition, analysis of the weather data observed widely is important. Then, in this study characteristic of the front and the relevance with generation of the heavy rain have been examined in analyzing the GMS images at the time of the disaster. From characteristics of vector field of moving cloud by the mutual correlating method between the GMS images, we have grasped front position and the generating position of the rainy area moving with the front. Also, we examined relationships between the front positions by the GMS images and the GPV data.
