Outline of Final Research Achievements

Characteristics of local heavy rainfall in the Fukuoka city are investigated on the basis of field observation. The data were taken with 16 rain gauges and 78 thermometers. The surface temperature in the case of local rainfall shows an increase of about 2℃ compared to that in the absence of rainfall. The vertical distributions of the humidity in localized rainfall and no rainfall cases differ obviously at elevations higher than 900hPa, whereas there is no difference between both near the ground.
