Correlation Between Hail Diameter and VILD in Bayannur

EasyChair Preprint no. 5653

Abstract

The vertical integrated water liquid content density(VILD) can be calculated using the ratio of the vertical integrated liquid water content(VIL) to cloud thickness. This paper processes the reflectivity factor data of hail-days observed by the new generation of weather radar (CINRAD-CD) in Linhe area of Inner Mongolia from 2012 to 2020, and combines hail size data collected by the hail-pad of each weather modification operation site, using the least squares method for regression fitting, and processing the VILD and the actual hail size. The results show that there is a good correlation between the VILD and the hail diameter on the ground. The power function model has the smallest cost value of 27.31, and using VILD as a recognition factor is more accurate than VIL. The power function model is fitted using hail-pad information, and the cost is 5.97, It can be concluded that the diameter of hail recorded by the hail-pad is more accurate, and the fitting result has certain reference significance for the estimation of hail particle diameter in Bayannur.
