The variability of drop size distributions (DSDs) within a storm lasted for 14 hours in Montreal, Canada, is investigated utilizing 1) 840 one-minute DSDs observed by a disdrometer, and 2) vertical profiles of reflectivity (Z) and vertical Doppler velocity (Vr) from a vertically pointing radar. Vertical Doppler velocity indicates that riming exists throughout the rain event. Based on the vertical structures of Z and Vr, we have identified three periods as a function of the degree of riming and examine the characteristics of the DSD variability. The fluctuation of the rain intensity shows the coherent structure with the decorrelation time of about 40 minutes. This emphasizes the nonstationary nature of the rain field. When riming and aggregation coexist, DSDs are narrower and show the pivoting around smaller diameters. As the degree of riming increases, DSDs become broader and then steeper when strong updraft appears. In addition, the average DSD shows peaks in small diameters associated with break-up of large raindrops. The exponent of R-Z relationships decrease with increasing degree of riming. The decorrelation time of the R-Z uncertainty is about 20 minutes. When aggregation and riming coexist, the characteristic number density N'<SUB>0</SUB> and diameter D'<SUB>m</SUB> are small. D'<SUB>m</SUB> increases rapidly and N'<SUB>0</SUB> remains its value when riming is dominant. Finally, when strong updraft exists, N'<SUB>0</SUB> dramatically increases whereas D'<SUB>m</SUB> slightly decreases.
