Transformation of Raindrop characteristics (Nov 24, 2015) of natural rainfall of Yellow River basin
Abstract
Raindrop characteristics, including speed and size of raindrops, in Zhengzhou city of Yellow River basin were analyzed through a natural rainfall on the loess slope. Results showed that the process of natural rainfall belonged to a parabola and counts, size and terminal velocity would increase with the rainfall intensity rising. Besides, the size and terminal velocity of natural raindrops were relatively scattered; In the process of individual rainfall, the terminal velocity and its peak value were mainly focused between 1∼3.4m/s and 1.4m/s, respectively. Size of raindrops were mainly consisted of 0.125-0.75mm, among which the terminal velocity of raindrops with a size of 0.125mm, 0.25mm, 0.375mm, 0.5mm and 0.75mm were primarily 1-3.4m/s, 1-4.2m/s, 0.8-3.4m/s, 0.8-3.4m/s, 1-2.6m/s, respectively.
