The maritime ports of Bangladesh have been advised to hoist local cautionary signal three, the weather department said on Thursday.

The signal is meant to alert vessels of a possible squall as a low pressure area has formed over the northeast Bay and adjoining areas, according to Bangladesh Meteorological Department.

Under its influence, a deep convection is taking place over the same area, it said.

Squally weather may affect the maritime ports, the North Bay, and the adjoining coastal areas of Bangladesh. 

"All fishing boats and trawlers in the North Bay have been advised to come closer to the coast and proceed with caution until further notice," the department said.

Low-pressure areas, where the atmospheric pressure is lower than that of surrounding locations, are commonly associated with inclement weather.

Deep convection refers to the thermally driven turbulent mixing that moves air parcels from the lower to the upper atmosphere.

Dhaka’s air ‘hazardous’; 2nd worst in the world this morning

As city dwellers are witnessing a huge flow of traffic, Dhaka has ranked second on the list of cities worldwide with the worst air quality with an AQI score of 387 at 9:30 am this morning (February 4, 2024).

Dhaka’s air was classified as ' hazardous ', according to the air quality index.

Ghana’s Accra, Pakistan’s Karachi and China’s Shenyang occupied the first, third and fourth spots on the list, with AQI scores of 423, 193 and 183 respectively.

When the AQI value for particle pollution is between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ is considered 'hazardous', posing serious health risks to residents.

The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them.

The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.

As per World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.
