The size distribution of raindrops

WebThe stationary size distributions for different rainfall rates are roughly parallel to each other when log f ( r) is plotted against r, f ( r) being the concentration density of drops of radius … WebAbstract Many observations have been made of size distributions of raindrops, aggregated snowflakes, graupel and hailstones under various meteorological conditions. The size distributions have been studied in conjunction with upper air soundings which were used to determine the original shape or snow crystal form of the hydrometeors. It was concluded …
