Abstract

Research was conducted for the drop size distribution (DSD), canting angle, and raindrop oscillation, which shows that the largest difference in ΔA corresponds to the equilibrium and oscillation shape models. The difference is less than 30%. Note that if drop oscillations are always present, then this difference should not be of concern since the two oscillation models produce comparable results, particularly below 60 mm h^-1. The gamma-model size distribution parameter μ appears to affect A_h the most, especially at rainrates above 40 mm h^-1. Oscillations and canting do not seem to alter A_h significantly.
