Heat wave: Even if it rains, it will be uncomfortably hot

Meteorologists say the ongoing heatwave will continue for a couple more days. If it rains, the temperature will drop a bit. But the amount of water vapor in the air will increase.

As a result, even if the temperature drops, the uncomfortable heat does not go away immediately. Such weather may also prevail during the upcoming Eid-ul-Fitr. Depending on the sighting of the moon, Eid in Bangladesh may be next Saturday or Sunday.

The country’s highest temperature was recorded at Ishwardi on Monday at 43 degrees Celsius, the second highest temperature in the country’s history. The highest temperature in Dhaka was 38.1 degrees Celsius on that day.

The country has been experiencing heat wave for two consecutive weeks since the beginning of April. Khulna division and Dhaka, Faridpur, Gopalganj, Manikganj, Narayanganj, Rajshahi and Pabna districts are affected by this heat wave. Mild to moderate heat waves are prevailing elsewhere in the country.

Meteorologist Shahinul Islam said, “The prevailing heat flow may continue for another couple of days. The trend of rain may increase around April 20-24 before and after Eid.”

He said that in the next 24 hours, the sky will be temporarily partly cloudy and the weather may remain dry across the country. A few places in Barisal, Chittagong and Sylhet divisions are likely to witness rain or thundershowers. However, there is no sign of it in Dhaka in a couple of days.

 

Because of which discomfort will increase

Department meteorologist Dr. Abul Kalam Mallick said that although the temperature was high during the heat wave from the beginning of April, the sweat was not too much, so the heat did not feel so uncomfortable.

Explaining this, the meteorologist said that till April 14, the sky of the country including Dhaka was cloudless. Besides, the south, south-westerly winds were not very active; The water vapor content was relatively low (down to 40%). In this condition, the temperature in the mercury rises, but the sweat is not too much.

“With isolated rain showers likely across the country next week, temperatures of 36-40 degrees Celsius will add to the feeling of discomfort along with water vapor.”

He said that after April 14, clouds started coming in Bangladesh as the extension of pubali low pressure spread. It is gradually increasing. Since April 19, due to the increase in water vapor in the air, the feeling of discomfort will increase even as the temperature drops.

The Meteorological Office says that there is a glimpse of light rain in the eastern part of the country including Sylhet, Chittagong. Rainfall trends may increase towards the end of the month. However, there is no sign of heavy rainfall for now.

Meteorologist SM Kamrul Hasan said that there is a possibility that the intense heatwave will subside in a week. Even if the temperature drops, the heatstroke may continue to be mild to moderate. The next week will increase discomfort due to water vapor.

There was not only fog but also smog in the early morning in summer

Abul Kalam Mallik said that the night sky was cloudless till April 14 in Bangladesh and adjacent areas of the subcontinent; Due to radiation, the temperature dropped to 22-26 degrees Celsius at night. As a result, between 5 am and 8 am at this temperature, water vapor in the sky has created a smog-like situation with the dust particles in the air.

“It’s not fog, it’s haze. Now that clouds are coming in, water vapor will rise. Night temperatures will also start to rise. As the difference between the maximum and minimum temperature decreases, the discomfort will also disappear.”
