Particle size distribution of rain drops that was different from that of Marshall and Palmer was observed at Hitoyoshi Radar Station in July 1969 and July 1970. It was tend to show N_D=const. at the region of D>1.5mm, and it was remarkable when precipitation rate R>20mm/hr. Using N_D=const., the relation of radar reflectity factor Z and precipitation rate R was estimated easily and speedily. This distribution was discussed with the use of coalescence growth theory, and the generating point of cell and its growth were deduced.
