| Outline of Final Research Achievements |
We statistically compared wind data at lower troposphere based on wind profiler radars with precipitation distribution data based on C-band weather radar in order to investigate the effects of interaction between terrain and lower wind on precipitation patterns in the Fukui plain. The results show detailed precipitation patterns in the Fukui plain are classified by wind at altitude lower than 1 km. In particular, localized strong rainfall often occurs in the northern area of Fukui plain in the condition that wind at altitude lower than 1 km is westerly. These results indicate the measurement of lower wind at altitude lower than 1 km is important on local weather forecasting.
