STUDY ON LOCAL AND REGIONAL PRECIPITATION BY USING RADAR-RAINGAUGE ANALYZED PRECIPITATION - A CASE STUDY ON MATSUYAMA PLAIN -

Abstract

 Though the radar-raingauge analyzed precipitation data is useful to analyze the temporal and spatial characteristics of precipitation, less attention has been paid on the impact of land-use on precipitation in study of the urban climate. This study focuses on the availability and the potential of the radar-raingauge analyzed precipitation data for the evaluation of local and regional rainfall. Thus, for this purpose two indices, “Rainfall intensity index“ and “Rainfall skewed index” has been introduced. We observed that the 7- year total precipitation shows the urban effect especially in warm season. These indices are promising for understanding the characteristics of precipitation events, though they hardly detect the urban effect on precipitation.
