The Applicational Analysis of Lightning Monitoring Data and Atmospheric Instability Parameters

摘要

In order to improve the accuracy of lightning forecasting, atmospheric stability parameters such as lifting index LI, convective available energy CAPE, normalizing convective available energy NCAPE, storms severity index ISS and the data of satelites, radar, lightning tracking, atmospheric electric field instrument in one thunderstorm are used in this paper . Results show that lightning tracking records and Curve changes of atmospheric electric field have good corresponding relationship, and lightning areal distribution can accurately reflect the evolution trend of thunderstorm. Based on the analysis, the indication and relativity of instability parameters and monitoring data are summarized here for lightning forecasting.
