Extreme heat waves are going around all over the world due to climate change
Atlantic to Pacific to the Indian Ocean, a warm air current has been blowing across most of the world’s oceans for the last two weeks. A similar warming spectrum has also been found in the Bay of Bengal, the Indian Ocean end.
In most of the world’s Seas, abnormal weather behavior has started to cause severe heat waves in the surrounding areas. Its impact is also falling in Bangladesh.
In Bangladesh, Syedpur of Nilphamari district had the highest July temperature in the last 40 years. Moreover, the maximum temperature in Rajshahi was the second highest after 1982.
More than half of the world is now burning fiercely. From Europe to China, the Middle East, India, Pakistan, and Central Asia, the maximum temperature fluctuates between 40 and 50 degrees Celsius.
The abnormal behavior of global weather is also affecting Bangladesh indirectly. That weather behavior may persist throughout much of the year.
A particular weather pattern has now developed over the Pacific Ocean, the El Niño–Southern Oscillation , the Indian Ocean, and the Bay of Bengal under the influence of the ‘Bicycle-IOD.’ As a result, the primary source of Monsoon is acting inactive sometimes and active at other times.
The Indian Ocean Dipole –IOD has become active. Due to this, a warm line has formed from the Indian Ocean to the Bay of Bengal. Due to this, the monsoon axis is inactive in Bangladesh, West Bengal, Assam, and Meghalaya. Monsoons are generally active over these regions, with heavy rainfall during June-July and August.
However, the Monsoon is causing heavy rains over a wide area, including Gujarat, India, Khyber Pakhtunkhwa, Pakistan, and Karachi. Over two hundred people have died in Pakistan alone in the last two weeks due to heavy rains.
It predicts no chance of rain except for the end of this month. There is a flash flood risk in late July or early August.
In this regard, Arifuzzaman Bhuiyan, Executive Engineer of the Flood Forecasting and Warning center, said,” There is no chance of rain except for the end of this month. There is a flash flood risk in late July or early August. The rest of the time is more likely to have a similar feeling of warmth.”
The United States Space Research Agency ” NASA ” released a map of a heat wave in different countries on July 15, 2022.
It showed that on July 15 afternoon, the temperature of the city of Seville in Spain rose to 42.2 degrees Celsius, the temperature of Ahvaz in Iran rose to 46.5 degrees Celsius, and the temperature of the city of Shanghai in China rose to 37.6 degrees Celsius.
Moreover, most major cities in the Middle East saw maximum temperatures between 45 and 50 degrees Celsius.
When asked, Mustafa Kamal, a researcher at the University of Saskatchewan in Canada, said,” There is no way to get rid of such hot conditions for now.
In this weather, one should drink plenty of water and saline. Avoid wearing colorful clothes. It is better to wear cotton clothes.”
According to the Meteorological Department, Bangladesh, Sayedpur in Nilphamari recorded the highest temperature in the country on Saturday 39 degrees Celsius.
Most of the area of the Rajshahi and Rangpur divisions of Bangladesh recorded maximum temperatures above 37 degrees Celsius.
