FE REPORT
The minimum temperature in the country dropped by 1.0°C within a single day and was recorded at 7.3°C in Panchagarh's Tetulia on Sunday.
Despite the fall in the minimum temperature, the geographical spread of the cold wave temporarily shrank.
But meteorologists warned the cold wave might expand in some southern districts starting as early as today (Monday).
The Bangladesh Meteorological Department (BMD) on Sunday said a mild to moderate cold wave was sweeping over 13 districts, including Rajshahi, Pabna, Naogaon, Dinajpur, Nilphamari, Panchagarh, Kurigram, Jashore, and Chuadanga.
This marked a significant decrease from Saturday, when 19 districts were affected.
The intensity of the winter fluctuated throughout the week, with the cold wave covering 24 districts on Thursday and 20 on Friday.
For the fourth consecutive day, Tetulia remained the coldest spot in the country.
Sunday's 7.3 degrees Celsius in the district was a slight drop from Saturday's 8.3°C.
With this, a trend of severe winter conditions continued in the northern tip of the country.
The season's lowest temperature so far was recorded last Wednesday in Naogaon's Badalgachi, where the mercury plummeted to 6.7 degrees Celsius.
While the northern region continued to shiver, the capital saw a temporary reprieve.
In Dhaka, the minimum temperature rose to 14.6 degrees Celsius on Sunday, a notable increase from Saturday's 12.4 degrees Celsius and Friday's 12.2 degrees Celsius.
Meteorologists pointed out that the widening gap between the maximum and minimum temperatures in the capital contributed to a relatively warmer feel on Sunday compared to the biting cold experienced earlier in the week.
However, weather experts warned that this relief might be short-lived. Kazi Jebunnesa, a meteorologist at the BMD, forecast that the cold wave was not dissipating.
The cold wave was likely to expand in some southern districts, she said, adding that the temperature elsewhere was likely to remain unchanged.
The Met office also said Bangladesh was experiencing the highest frequency of dense fog in the last 20 years.
Rising air pollution levels increased the concentration of fog as suspended particulate matter mixed with moisture in the air.
Meteorologists and environmentalists said air pollution was playing a key role in increasing fog density as dust particles in the atmosphere combined with fog droplets.
Meanwhile, environmental experts warned that the combined effects of El Niño and La Niña were causing noticeable changes in the country's weather patterns.
They cautioned that Bangladesh was gradually moving towards greater exposure to extreme weather events.
Without effective measures, they feared the country's traditional six-season climate cycle could be disrupted in the future.
