Analysis of heat wave and mean maximum temperature for the months of March to June over Vidarbha during last 50 years

Abstract

A study has been carried out to analyze the trend of heat wave and maximum temperature during March to June over Vidarbha. Central India, mainly the Vidarbha region of Maharashtra State, experience extreme temperatures during the month of March to June. Special cases have been identified where most of these stations have reported maximum temperature greater than or equal to 45°C and an attempt has also been made to determine its cause. Various studies have been taken up for examining the trend in heat waves over Indian region and its impact on various sectors. This study focuses on the statistical and meteorological aspects of heat wave. It was found that four out of seven stations displayed a positive trend in the number of heat wave days and three out of six stations displayed positive trend in severe heat wave days.It was observed that for the average maximum temperature,only Buldhana station showed positive trend for all four months and Amravati station showed negative trend for April and June months following Mann Kendall test statistics.
