New Delhi: Parts of Delhi are expected to experience a severe heat wave on Wednesday, with maximum temperature likely to hit the 40 degree mark, India’s Meteorological Department said.
Severe heatwave conditions are also expected to persist Thursday.
IMD officials said a prolonged dry spell had led to “severe” weather conditions in northwest India. “The heat wave over northwest, central and western India is expected to continue for the next four to five days.” For the plains, a “heat wave” is declared when the maximum temperature is above 40 degrees Celsius, and at least 4.5 notches above normal.
A “severe” heat wave is declared if the deviation from normal temperature is greater than 6.4 notches, according to the IMD.
Parts of Delhi were rocked by severe heatwaves on Tuesday and eight weather stations in Delhi recorded their maximum temperature above 40 degrees Celsius, with mercury in Narela, Pitampura and the Sports Complex station crossing the 41 degree mark .
Another heat wave in Delhi is likely from April 3-5.
According to the non-profit green think tank Climate Trends, high temperatures in the second half of March have seen an increase over the past three years.
The capital recorded a maximum temperature of 40.1 degrees Celsius on March 30. The highest March temperature ever (40.6 degrees Celsius) was recorded on March 31, 1945.
“The absence of a weather system and the presence of an anticyclone over Rajasthan and neighboring Pakistan have pushed warm winds into northern and central India. March will end on a relentless warmer note until early April,” said Mahesh Palawat, Vice President, Meteorology and Climate Change, Skymet Weather.
Light winds and dry weather will again raise temperatures in northwest India, bringing heatwave conditions, he said. “While we expect a heatwave to hit parts of central and northwestern India by the end of March, it was not expected so early in the season.
But I wouldn’t be surprised either, because we have been witnessing a gradual increase in daytime temperatures for the past few years. Record-breaking maximum temperatures are now here to stay with rising global average temperatures,” he said.
Both rural and urban populations are vulnerable to heat-related mortality. People with low levels of education and socioeconomic status, the elderly, and those who live in communities with less green space are more likely to experience heat-related mortality.
