Definitions of heat wave discussed in the present paper

Definition	Days		Region	Reference
“A time interval of at least 2 days with maximum apparent temperature exceeding the 90th percentile of the monthly distribution.”	2	Europe		(D’Ippoliti et al. 2010)
“If the daily maximum temperature exceeds 30 °C for a continuous period of 3 days, it is termed as heat wave in Hilly regions of India.”	3	Hilly Regions, India		(Deoras 2016)
“If the daily maximum temperature exceeds 40 °C for a continuous period of 3 days, it is termed as heat wave in plain regions of India.”	3	Plain Regions, India		(Deoras 2016)
“If the daily max temperature exceeds 37 °C for a continuous period of 3 days, it termed as heat wave in coastal regions of India.”	3	Coastal Regions, India		(Deoras 2016)
“Period ≥ 3 consecutive days with maximum temperature above the 90th percentile of daily maxima temperature, centered on a 31-day window.”	3	Africa		(Ceccherini et al. 2017)
“The top 5% ($32.65uC) of daily maximum temperatures for a continuous 5 days period.”	5	Brisbrane, Australia		(Tong et al. 2010)
“Absence of normal pre-monsoonal rainfall which is brought by aberrant strong low-level westerly winds and weak southerlies for consecutive 10 days is defined as heatwaves.”	10	Bangladesh		(Nissan et al. 2017)
“If the sweltering climate continues for 16 successive days, with temperatures achieving 36 °C, it is termed as heatwave.”	16	Taiwan		(Lin et al. 2013)
