چکیده

This paper presents the correlation analysis between lightning flashes and rainfall rate of a thunderstorm when flash flood event happened in Melaka on 11 August 2020. Four types data have been collected from electric field mill (EFM), fast antenna (FA) system, constant altitude plan position indicator (CAPPI) radar world wide location network (WWLLN). Two storms detected by EFM occurred 04:00:00 14:00:00. The FA system recorded total 33 had with highest number occurrence which positive narrow bipolar (+NBE) around 21 flashes, maximum reflectivity during first storm were 8 mm h-1 37 dBZ, respectively (light rain). During second storm, there was 980 429 (IC), value is 50 (heavy Analyses also show close link major thunderstorms systems flooding regional scale.

An improved lightning flash rate parameterization developed from Colorado DC3 thunderstorm data for use in cloud-resolving chemical transport models

Accurate prediction of total lightning flash rate in thunderstorms is important to improve estimates of nitrogen oxides (NOx) produced by lightning (LNOx) from the storm scale to the global scale. In this study, flash rate parameterization schemes from the literature are evaluated against observed total flash rates for a sample of 11 Colorado thunderstorms, including nine storms from the Deep C...

NO signatures from lightning flashes

In situ measurements of cloud properties, NO, and other trace gases were made in active thunderstorms by two research aircraft. Concurrent measurements from a three-dimensional (3-D) VHF interferometer and the 2-D National Lightning Detection Network were used to determine lightning frequency and location. The CHILL Doppler radar and the NOAA-WP-3D Orion X band Dopper radar were also used to me...
