No Respite as North India Continues to Reel under Heatwaves
The IMD said the heat wave conditions are likely to decrease in intensity and area coverage due to the expected southwesterly winds from the Arabian Sea. New Delhi: Due to dry westerly or southwesterly winds from Pakistan to northwest India at lower levels, heat wave conditions in some pockets over the northern plains, including Punjab, Haryana, Chandigarh and Delhi, north Rajasthan, Uttar Pradesh and northwest Madhya Pradesh, are likely during the next two days, the India Meteorological Department (IMD) has said. It said heat wave to severe heat wave conditions were observed in isolated places over Jammu on Wednesday. Severe heat wave conditions were observed at isolated places over northeast Rajasthan as well, it said. The IMD further said the heat wave conditions are likely to decrease in intensity and area coverage due to the expected southwesterly winds from the Arabian Sea. “However, due to an increase in the humidity in association with these winds, the human discomfort will continue during the next seven days,” IMD director general Mrutyunjay Mohapatra told PTI. For the plains, a “heatwave” is declared when the maximum temperature is more than 40°C, and at least 4.5 notches above normal. On Thursday, Delhi recorded a maximum temperature of 43.1°C, the highest in July since 2012, with the IMD saying there is “no chance” of monsoon reaching the city till July 7. After that, the region will witness below-normal rainfall till the middle of this month. The last time monsoon arrived so late in Delhi was in 2012. Normally, monsoon reaches Delhi by June 27 and covers the entire country by July 8. The national capital had recorded a maximum of 43.5°C on July 2, 2012. The monitoring station at Mungeshpur recorded a maximum temperature of 45.2°C, the highest in the city on Thursday and eight notches above normal. A severe heatwave baked Lodhi Road (43°C), Ridge (43.9°C), Narela (43.4°C), Najafgarh (44°C) and Pitampura (44.3°C), where the maximum temperature was at least seven degrees Celsius above normal. In the hill stations, Solan in Himachal Pradesh has recorded a high of 35.5°C, whereas Thoise, located in Ladakh’s Nubra Valley, has recorded a maximum temperature of 31°C degrees Celsius, according to IMD data. The southwest monsoon has covered the entire country but has eluded Haryana, Delhi, parts of Punjab, west Rajasthan and west Uttar Pradesh. Looking at heatwaves from a disaster perspective According to IndiaSpend, heatwaves killed about 6,167 people in India over eight years to 2018, of which, 2,081 deaths, or 34% of the deaths, were in 2015 alone, when an intense series of fifth-deadliest heatwaves on record swept across India. However, these numbers may be unreliable because only deaths due to heat exhaustion, heat cramps and heat strokes are recorded. A heat stroke occurs when the body is unable to control its temperature. This condition can cause death or even permanent disability. Besides, higher temperature can also lead to respiratory problems as they contribute to the build-up of harmful air pollutants. Despite being the third-biggest natural cause of death in the country, heatwaves have still not been declared as a natural disaster. According to Statista, two people died of heatwaves in India in 2020 as compared to 498 in 2019. The year 2013 witnessed the second-highest number of deaths due to heatwaves at 1,433. Peak power demand According to NDTV, Punjab’s peak power demand touched a whopping 14,500 megawatt (MW) so far. Due to extreme heat amid power shortage, chief minister Captain Amarinder Singh has ordered to cut short work hours in state government offices from Friday till July 10. He also said that the agriculture sector needed to be prioritised for uninterrupted power supply, as farmers were losing paddy transplantation time due to power breakdowns. According to Hindustan Times, Delhi’s peak power demand on Thursday crossed the 7,000MW mark – the highest in the last two years. Officials in the power department told the daily that the demand may further go up to 7,400 MW, if the ongoing heatwave in the city continues. According to an analysis by Centre for Science and Environment, 33.6% of Delhi’s total power needs come from coal-based thermal power plants that do not meet emission norms under the Environment Protection Act, 1986, DownToEarth had reported last year. Overall, of India’s installed power generation capacity of 382.15 gigawatt (GW), the coal fuelled projects account for 53% or 202.67 GW.
