| Outline of Final Research Achievements |
In recent years, torrential rainfall has occurred frequently and early prediction is important. In this study, we focused on the "cloud" which is the preliminary stage of precipitation, and examined the observability of cloud formation and rainfall from ground weather observation data such as solar radiation, rainfall and atmospheric pressure.
Analysis of the spatiotemporal characteristics of atmospheric pressure showed that the atmospheric pressure began to rise 1 hour before the occurrence of local rainfall and this pressure change could be explained by the occurrence of cumulonimbus clouds.
In addition, the solar radiation distribution estimated from the photovoltaic power generation is in good agreement with cloud images by the all-sky camera and rainfall occurrence. The dense spatio-temporal observation data of solar radiation could be useful for the monitoring of clouds and precipitation.
