कोहरा

कोहरा क्या है?

Fog forms when air temperature drops to the dew point or when moist air moves over a cooler surface. Radiation fog forms on clear, calm nights over land. Advection fog forms when warm moist air flows over a cooler surface (common on coasts). In South Asia, dense fog in the Indo-Gangetic plain during December–January causes major transport disruptions.
