Wind Direction Shifts
In winter, dry continental winds flow from the North-West, transporting pollutants from upper India. Conversely, during summer and monsoon, oceanic wind from the Bay of Bengal sweeps in, bringing clean air.
Thermal Inversion
During colder months (November–February), warm air acts as a lid over the cooler air near the ground. This thermal inversion traps traffic smoke, dust, and industrial particulate matter close to the surface.
Industrial & Traffic Load
Heavy commercial vehicle transit (diesel engines) through connecting highways and industrial activities in Howrah and surrounding districts contribute a steady baseline of fine particulates.
