大陆性浓积云云滴谱离散度影响因子的飞机观测研究
Aircraft observations of influencing factors of cloud droplet relative dispersion in continental cumulus congestus clouds
摘要
Abstract
By using the aircraft observation data from the artificial precipitation and lightning protection technology center in Shanxi Province on July 30,2020,the time and height variation of microphysical properties such as cloud droplet relative dispersion and the influencing factors of cloud droplet relative dispersion were analyzed.Results show that the relative dispersion of the continental cumulus congestus clouds first increases and then decreases with the increasing of height,but the range is small.The relative dispersion is positively correlated with cloud droplet number concentration and liquid water content.The correlation between the relative dispersion and the mean-volume radius changes from positive to negative with the increasing of the mean-volume radius,and the correlation between the relative dispersion and the vertical velocity is positive.Given the influence of collision-coalescence process in precipitation clouds on relative dispersion,it is suggested that the cloud droplet relative dispersion should be parameterized with the consideration of the collision-coalescence process in the future.关键词
