According to a study conducted by the researchers from Indian Meteorological Department (IMD) and the Indian Institute of Technology, Delhi (IITD), there was a steady increase in the occurrence and duration of hot days in the Northwestern and Southeastern regions in India in the recent years. Analyzing weather data from 1951 to 2015 to understand the incidence and duration of heatwave conditions in India, the study found that the average heat wave duration in the Northwestern and Southeastern regions of India has increased during this period.
However,
the average duration of hot days has decreased over most parts of India from
1951 to 2015, except in the northwest and southeast regions. According to the
researchers, this may be due to the increase in average heatwave duration in
the Northwestern and Southeastern regions during the same period as hot days could
be upgraded to the heatwave category as temperature soars.
