What is a heatwave?
According to IMD, "Qualitatively, heat wave is a condition of air temperature which becomes fatal to the human body when exposed. Quantitatively, it is defined based on the temperature thresholds over a region in terms of actual temperature or its departure from normal. In certain countries, it is defined in terms of the heat index based on temperature and humidity or based on the extreme percentile of the temperatures. A heatwave is considered if the maximum temperature of a station reaches at least 40 degrees Celcius or more for Plains and at least 30 degrees C or more for Hilly regions."
