Climate Change crisis: IMD to change parameters to declare heatwaves
The India Meteorological Department (IMD) plans to revise the criteria for declaring heatwave conditions in India due to the inadequacy of current parameters. This change is particularly important for Kerala, which has faced severe heat and humidity this summer. The IMD aims to implement new parameters that will allow for more effective heatwave warnings in the state.
- ▪The IMD will change the criteria for declaring heatwaves as current parameters do not suit India's geographical conditions.
- ▪Kerala has experienced unusually high night temperatures this summer, prompting the need for revised heatwave warnings.
- ▪The current heatwave declaration parameters require conditions to be recorded at two stations, which is challenging in Kerala.
