摘要
The canting angle distribution of raindrops derived separately from a 2-D video disdrometer and from an S-band advanced polarimetric radar are presented. In the former case, measurements were made in both natural and artificial rain. The canting angles showed a symmetric distribution about 08 with a standard deviation (sigma(beta)) of 7 degrees-8 degrees in low wind conditions and 12 degrees in moderate wind conditions. In the radar-based estimates, the histogram of sigma(beta) derived from data obtained during a light stratiform rain event with embedded convection shows the mode to be around 7 degrees, with a significant positive skewness. Around 16% of occurrences exceeded 10 degrees and 3.3% exceeded 15 degrees.
