This year’s winter is likely to set in at the end of the current month while the fog which has overcast the country excluding Khulna and Chittagong districts will take more two or three days to go, said meteorologists of the Bangladesh meteorology department.
‘The full-fledged winter will take at least two weeks to set in in the country as the pre-winter frontal systems are yet cross Bangladesh, which are now passing through the countries in the Middle East,’ Syed Abul Hasanat, a meteorologist of Met Office told New Age on Sunday.
‘Winter becomes chillier when the wave of pre-winter frontal systems which include rains and cold passes through our subcontinent,’ he said, adding, ‘Moreover, the absence of Z-wind, recent mild cyclones and depressions on the Bay of Bengal have caused the delay in setting in of the winter.’
He said the Z-wind was now blowing much above the country and that was why it could not leave any impact on the country’s weather.
Referring to the fog that has overcast Bangladesh since Saturday, SM Quamrul Hassan, an assistant meteorologist of the met office said, ‘Moisture in the air creates fog. The moisture is now trapped in the air in the absence of normal flow of the wind, eventually helping create fog.’
‘It would take two or three days for the fog to evaporate and once the fog disappears, the temperature will fall slightly,’ he said, adding, ‘The minimum temperature is yet to go below the normal even in December this year whereas the minimum temperature went below the normal one in November in the last year.’
However, the meteorologists could not give the exact reasons as to why the winter is taking time to set in recently.
Meanwhile, the dense fog is hampering the normal life in different parts of the country with the disruption of the road, river and air communications.
A hajj flight which was scheduled to land at the Dhaka international airport on Saturday was compelled to land at Chittagong airport because of fog in the capital.
Ferry services on Daulatdia-Patuaria route in the river Padma remained suspended for several hours Sunday morning because of fog.
Around 150 vehicles got stranded in the mid-river causing untold sufferings to the passengers.
The New Age correspondent in Barisal reports that dense fog over different rivers and highway routes from mid-night till late morning had delayed the movement of the water and road transports in the southern region by 6 to 8 hours as visibility needed for transport movement was rapidly lost.
The Launch and Bus Owners Associations, BIWTC and the BRTC sources said water and road transports plying in the Barisal region had reached their destinations at between 11:00 am and 1:00 pm.
