Research Abstract

Firstly, a short-term rainfall prediction method using a three-dimensionally scanning radar is developed based on the analyses of time variations of rainfall distribution. The method is physically based one in the sense that the water balance is taken into consideration.
Secondly, a method of estimating rainfall distribution using geostationary meteorological satellite data is developed with the accuracy of the estimation. One can get rainfall distribution for every an hour in the wide area which includes the area of, for example. Radar network over Japan.
Nextly, a stochastic model of rainfall distribution is proposed based on the statistical analysis using radar and satellite data following to the discussion about how stochastic rainfall distribution models should be used to making planning for disaster prevention.
Finally, two methods of using satellite data into the physical based prediction method. One of then is a method of predicting translation vector of instability field using satellite data. The other is a mth odestimating three-dimensional rainfall distribution using horizontal rainfall distribution. Wing to the development of these two methods, the short-term rainfall prediction system has been completed.
