New Delhi:

The simmering heat wave continues to roast people in many parts of the country with Andhra Pradesh sizzling at 45.5-degree celsius even after rainfall in some places including Himachal Pradesh and Uttar Pradesh. 

As the mercury reached the 43-degree mark in seven towns and the 40-degree mark in at least 12 places, the MeT office said that heatwave conditions may intensify.

In the past four years, severe weather conditions has claimed over 4,620 lives. Of that figure, a whopping 4,246 people died in Andhra Pradesh and Telangana alone.

According to the Ministry of Earth Sciences, in 2016nearly 1,600 people died due to erratic weather conditions, of which 557 casualties were to the severe heat wave.

2015 witnessed 2,081 deaths due to severe heat wave while549 people died in 2014.

In 2013, the severe heatwave conditions killed 1,443people, of which the unified Andhra Pradesh state registered1,393 casualties.

The figures, however, are larger across the country as causes other than the direct reasons like heat stroke and dehydration are seldom accounted for, said Dileep Mavlankar, Director of Gandhinagar-based Indian Institute of PublicHealth that has been working with the Ahmedabad MunicipalCorporation on a heatwave action plan.

"For instance, dehydration also leads to respiratory and renal failure, especially for those who are prone to heart and kidney ailments. Infants and the elderly top the list in casualties," he said.

"In 2010, Ahmedabad recorded 65 deaths due to the heat wave, but in the same period, there were 800 more deaths," Mavlankar said.

Since last year the IMD has started issuing heatwave alerts. A heatwave is declared when the temperature crosses45 degrees Celsius.

If the temperature rises to 4 to 5 degrees above normal, then the condition is termed as a 'heat wave'. If the variance is over 6 degrees above normal, then it is classified as a severe heat wave'.

With global temperatures on the rise, the instances of heat wave are increasing. Mo ES figures reveal that there were74 days of the severe heatwave on an average between 1961 and1970. The figure declined to 34 between 1971-1980.

Between 1981-1990 and 1991-2000, 45 and 48 severe heatwave days were recorded respectively.

However, there was a sharp increase in figures in 2001-2010 with the number of severe heatwave days peaking to 98.The last decade is one of the warmest ever recorded.

With every year in the current decade registering warmer climates, it may be fast racing towards becoming the warmest10-year period. The IMD has declared 2016 as the warmest year ever recorded since 1901.

Global warming is the obvious reason behind the severe heat wave, said Laxman Singh Rathore, former Director General of the India Meteorological Department, but local factors also aggravate the situation.

For instance, the case of Telangana, Andhra Pradesh andOdisha that have seen maximum deaths due to heat wave.

"In the summer season, there is an upper air anti-cyclone over Rajasthan and Gujarat. It sucks hot dry desert air which gets transported to Madhya Pradesh, Andhra Pradesh, Telangana and Odisha.

"Persistent advection of this hot dry air gives rise to heatwave conditions over these regions. Once this anti-cyclone moves to the Arabian sea, heatwave conditions subside," said AK Jaiswal, a former scientist with the IMD who has published a research paper on this topic.

The Centre as well as the states this year have come up with an action plan to minimise deaths related to heat waves.

In a seminar last month, attended by representatives of several states and NGOs, stakeholders resolved to restrict the death figures to double digits.

"Last year, states like Maharashtra, Odisha, AndhraPradesh and Telangana came up with a strategy to minimise deaths. This year, we have added states like Uttar Pradesh, Bihar, Madhya Pradesh, Bihar, Jharkhand, Punjab, Delhi and Haryana and given them several Dos and Don'ts," said M Rajeevan, Secretary, Ministry of Earth Sciences.

The Haryana government has sent out an advisory through newspapers on how to take care oneself during a heat wave.

Rajeevan said the states have been told to follow the Ahmedabad pattern to reduce heatwave-related deaths.

The Ahmedabad pattern comprises measures like sending out warnings to hospitals about the heat wave and what kind of patients they can expect.
"This will help hospitals to stay alerted and stock medicines accordingly. This will also help them minimise casualties," Rajeevan said.
