According to the Bangladesh Meteorological Department, the temperature across the country on December 20 and 21 was much lower than the average for the same period of the last 30 years. During the last two days, the average temperature in different parts of the country was 9-15 degrees Celsius at night and 22-24 degrees Celsius during the day.
According to meteorologists, the temperature is 1-5 degrees lower than the national average for the last 30 years. That is why even though mild to moderate cold wave is prevailing in 10 districts of the country at the moment, lower than normal temperature is being felt all over the country.
Meteorologist MD Abul Kalam Mallick said that the feeling of winter is more this year. Temperatures across the country, especially in the northern and north-western districts, may remain below normal for the next few days.
The Meteorological Department says that according to the general temperature calculation of Bangladesh if the minimum temperature in a large area is between 8 to 10 degrees, it is called a mild cold wave. If the temperature is between 6 and 8 degrees then it is called moderate cold flow. But if the temperature drops below 6 degrees Celsius then it is considered severe cold.
The lowest temperature in the country this morning was recorded at 9.3 degree Celsius in Chuadanga. The northern district has been recording the lowest temperature for three days in a row.
Cold weather is disrupting day-to-day life in the district and the poor are the worst sufferers.
Moderate to thick fog may occur over the river basins and light to moderate fog may occur elsewhere over the country during late night till morning, said a regular bulletin of Bangladesh Meteorological Department (BMD).
"The existing temperature may rise a little from Sunday," said Md Shahinul Islam, a meteorologist of BMD.
Weather may remain dry with temporary partly cloudy sky over the country.
Night temperature may rise slightly and day temperature may remain nearly unchanged across the country.
The low pressure area over southeast Bay and adjoining area persists. One of its associated trough extends up to northeast Bay.
UNB's Chuadanga correspondent reports that poor people, especially daily labourers, are the worst sufferers due to this cold spell. Many of them preferred to remain indoor due to the shivering weather.
Movement was also disrupted due to poor visibility caused by dense fog.
People are thronging the local markets to buy warm clothes.
Rakibul Hasan, in-charge of the Chuadanga Weather Observatory Centre, said, "The weather department has recorded a minimum temperature of 9.3 degree Celsius on Saturday which is the lowest temperature across the country this year. The mercury may fall in the coming days."
Meanwhile, the hospitals in the districts are overwhelmed with patients with cold-related diseases.
The UNB correspondent found that over 150 children and many adults are admitted at the outdoor facilities of hospitals.
Dr. Mahbubur Rahman Milon, a child specialist of Chuadanga Sadar Hospital, said, "As a mild cold wave is sweeping over the district, the number of patients with cold-related diseases are increasing day by day. All the physicians and staff are struggling to provide healthcare services to the patients."
