India to launch its own heat index next year to quantify heat hazard

In News
  • India will launch its own heat index next year to quantify the impact of heat on its population and generate impact-based heatwave alerts for specific locations.
About Heat Index
  • The IMD is now developing a new multi-parameter product called the “heat hazard score,” which will integrate other parameters such as wind and duration of exposure, making it an effective indicator of heat stress for people.
  • The heat hazard score will be operational next summer season and will be used to issue impact-based heat wave alerts for specific locations.
  • One major difference between the heat index of the US and India’s heat hazard score is that the latter will consider other parameters that aggravate heat situations such as minimum temperature, wind, and exposure duration.
Heat Wave hazard
  • According to IMD, there will be an increase in the maximum temperature and heatwave days in May for the eastern and central-eastern regions of India.
  • IMD data demonstrates that there has been a 24% rise in the number of heatwaves from 2010 to 2019 when compared to 2000 to 2009.
  • The Fifth Assessment Report of the Intergovernmental Panel on Climate Change also indicates that the major climate risk for south Asian countries will be the rising mortality rate due to heat waves.
  • Heat waves have a significant impact on human health, leading to cramps, exhaustion, stress, heat stroke, and even death. Individuals who are old, young, have heart and breathing problems, kidney diseases, and mental disorders are at a higher risk of being affected.
