2015 Indian heat wave

According to the Indian Meteorological Department (IMD), a heat wave is qualified when air temperatures of at least 40 °C (104 °F) in the plains or greater than 30 °C (86 °F) in the hilly regions. For the IMD classification of heat waves, temperatures greater than 46 °C (114.8 °F) are considered and classified as severe heat waves. Every year India experiences severe heat waves in summer, but in the year 2015, casualties were abnormally high. Most of the deaths were concentrated in Andhra Pradesh, Telangana, Punjab, Uttar Pradesh, Odisha and Bihar. More than 20,000 people have died of heat-related causes in India since 1990. In the recent past, the most severe period of hot weather occurred in 1995, when 1,677 people died due to a series of heatwaves. 793 people died in 2011 while 1,247 died in 2012 due to heat related causes. In 2013, 1,216 people died due to the heat. The casualties crossed the mark of previous years rapidly in 2015.{{cite web ==Causes==

The heat wave was caused in large part by sparser pre-monsoon season showers, which brought less moisture than normal to the area, leaving large parts of India arid and dry. The sudden end of pre-monsoon rain showers, an uncommon trend in India, has contributed to the heat waves. Additionally, the monsoon season is later and further south than the normal trend. This weather pattern, coupled with the El Niño effect, which often increases temperatures in Asia, combined to create the record high temperatures. High humidity compounded the effects of the temperatures on residents. ==Affected areas==
