Thunderstorm nowcasting is an important function for the severe weather forecaster. The usual method is for radar to detect thunderstorms, and for downstream systems to generate ’threat areas’ for issuing warnings. However, these threat areas are difficult for other systems to work with as they are not mathematically well defined. In this paper we develop an algorithm, THESPA (THunderstorm Envi...

Considering the importance of water and computing the amount of rainfall runoff resulted from precipitation in recent decades, using appropriate methods for predicting the amount of runoff from rainfall date has been really essential. Rainfall-runoff models are used to estimate runoff generated from precipitation in the catchment area. Rainfall-runoff process is totally a non-linear phenomenon....

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:...

In Bangladesh, the lightning during a thunderstorm has recently been officially declared as natural disaster, resulting in numerous fatalities each year, especially country's northeast. This study aims to look into relationships between and climatic variables, spatial distribution of deaths, people's perceptions disaster's consequences adaptation measures, influencing factors that make people v...

The probabilistic distribution of the thunderstorm phenomenon during the pre-monsoon season (1 March to 18 June) over Pune, a tropical Indian station, has been examined with the help of Markov chain models using daily thunderstorm data for a period of 11 years (1970–80). The data have also been tested using Akaike’s information criterion. This test has clearly indicated that the first-order Mar...

One of the most significant consequences of global warming due to increase in greenhouse gases would be an increase in magnitude and frequency of extreme precipitation events. In the present study the trends in extreme rainfall indices for the period 1901-2000 were examined for 100 stations over India. The trends for the southwest monsoon season and annual period were calculated separately. The...
