Fog

Tiny water droplets hanging in the air close to the ground cause fog, a common weather phenomena that impairs visibility. It arises as the air becomes saturated with moisture when temperatures drop, particularly in the early morning or late at night. It resembles a low-lying cloud.

Over the Indo-Gangetic plains, which include Delhi, Uttar Pradesh, Punjab, and Haryana, thick fog usually forms around December and January. Fog is created when moisture condenses into tiny droplets, air near the surface hits the dew point, and the ground cools quickly at night.

Fog might linger for several hours into the morning due to calm breezes and heavy humidity. Transportation and safety are significantly impacted by fog. At major airports, it can cause airline delays and cancellations, interfere with train services, and restrict visibility to a few meters.

For instance, the recent heavy fog in Delhi-NCR caused visibility to drastically decline, resulting in the cancellation of more than 100 flights and extensive travel disruption.

Because pollution particles from industry and automobiles serve as condensation nuclei around which water droplets condense, urban fog can be more severe in urban areas. This makes fog denser and more persistent than in rural areas, and can mix with pollutants to create smog, worsening air quality and health risks. 

To help people plan their travels safely and lower the number of accidents, authorities and meteorological departments issue notices and advisories during periods of severe fog.

Fog becomes deeper and more persistent than in rural areas, worsening air quality and health risks. Additionally, it can mix with pollutants to create haze.

By using fog lights, slowing down while driving, and checking weather forecasts before travelling, one can minimise the risks associated with fog.
