Precipitation analysis for several heavy rainfalls that occurred in Nagoya City was performed based on 10-minute and hourly precipitation data. Rainfall distribution analyses showed that a rain band in the direction of the prevailing wind at middle levels was formed in 9 out of 10 major heavy rainfall events in past 56 years. The rain band consisted of aligned heavy-rain cells of about 5–10 km diameter that traveled successively along the rain band that was generated on a meso-scale convergence line. Also, the result of rainfall analysis using 10-minute precipitation data was compared to rainfall distribution based on XRAIN (X-band polarimetric RAdar Information Network, that was installed in Nagoya area in 2010) for the rainfall event in 2011 and its validity and precision was evaluated.
