Dhaka dwellers were taken aback on Monday when thick fog suddenly covered the sky amid a bright sunny weather.
It is the fifth day of Bangla month Chaitra.
The following month Baishakh marks start of the lunar calendar and the advent of hot summer. Although unusual, the phenomenon is not abnormal for the season, meteorologists have said. The fog started to engulf different areas in Dhaka around 8am. The situation remained unchanged till 11am. “This is not totally abnormal. Air pollution could have played a role,” said senior BMD official Ruhul Quddus.
Meteorologists term such fog as ‘mist’ that brings down the visibility level between 1,000 to 2,000 metres. Fog is when the visibility level goes below 1,000 metre. Fog occurs early in the morning if temperature drops at night, Quddus said. Amount of water vapour increases at the lower level of clouds creating foggy weather in dusty areas, said the Bangladesh Meteorological Department official.
“This is the month of March and clouds are visible at places. Mists are occurring due to dusts. We can conclude that air pollution is the reason in case the situation persists.”
