Application of Doppler Radar Parameters in Hail Cloud Identification in the Ili River Valley

The Ili area of Xinjiang is one of the most hailstorm affected in the northwest of China, but hail Doppler radar and radiosonde data analysis in that region is poor. By analyzing the temporal and spatial distributions of the hail storms in Ili area and the early warning index of radar and radiosonde measurements, a hail storm occurrence law is revealed, which is of great significance to improve the level of early-warning and actively prevent hailstorm disaster.In this paper we analyze CINRAD/CC, radiosonde and ground stations data collected during ten years of acquisition, from 2006 to 2017, and obtain hail distribution and properties in Ili area. This analysis provides a deepest understanding of local hail storm events and gives an important contribution to early-warning methods.
