| Research Abstract |
A new method to predict spatial correlation characteristics of rainfall intensity from cumulative distributions of rainfall intensity measured by satellite-borne rain radar and those measured by ground-based rain gauge. By applying this method to the data obtained by the Precipitation Radar aboard the Tropical Rainfall Measuring Mission Satellite, the spatial correlation characteristics are estimated for the areas around 52 meteorological stations all over Japan. As a result, the spatial correlation characteristics are found to show clear regional dependence in central and western Japan that are consistent with our empirical knowledge about rain climatology.
