Difference in Raindrop Size Distribution and the Z-R Relationship with Elevation

[摘要] Comparisons were made between the Z-R relationships which were obtained from the data taken at three elevations 3.4, 2.1 and 1.3 km above the sea level along the eastern slope of Mt. Fuji. The precipitation observed was considered as generated from clouds of the warm-rain type. Raindrops were sampled by using filter paper during two shower rains. The Z-R relationships at each elevation were as follows : Z=48 R1.11 (3.4km) Z=88 R1.28 (2.1km) Z=240 R1.48 (1.3km) The significance of the difference between the parameters was consistent with the tendency in the showers in Hawaii Island which was interpreted by Fujiwara (1967) through accretion and evaporation.
