Northwest, central, south-central India new heatwave hotspots, says study
Northwestern, central and south-central India are new hotspots of intense heatwave over the past 50 years, a study has said.
The study also highlights the need for developing effective heat action plans in the three heatwave hotspot regions with a focus on different vulnerabilities among the inhabitants.
A team of researchers led by RK Mall, including Saumya Singh and Nidhi Singh from the Department of Science and Technology, Mahamana Centre of Excellence in Climate Change Research (MCECCR) at Banaras Hindu University, studied the change in spatial and temporal trends in Heatwaves (HW) and Severe Heatwaves (SHW) over the past seven decades in different meteorological subdivisions of India.
This work has been supported under the Climate Change Programme of the Department of Science and Technology. The study published in the journal ''International Journal of Climatology'' links the association of Heatwaves and Severe Heatwaves with mortality over India.
Importantly, the Heatwave and Severe Heatwave events were found to be positively correlated with mortality in Odisha and Andhra Pradesh, highlighting that human health is highly susceptible to severe heatwave disasters.
