Abstract
To investigate the radar reflectivity of falling snow, a continuous observation of size distributions of snow particles was made The fall velocity in relation to the melted diameter of snowflakes was studied simultaneously. The results show that a definite relationship between the radar reflectivity Z and the intensity of snowfall R exists for a duration of an hour or so. With the change in the degree of aggregation of snowflakes, an abrupt change of the coefficient occurs. The coefficients are some 3 to 10 times as great as that in MARSHALL'S relation. A brief discussion of the observed size-distribution curves is made.
