Why did North India experience heavy fog last week
An explanation of the factors contributing to the extreme foggy conditions in North India during the specified period.
- Cold Weather: The main reason for the heavy fog in North India last week was the cold weather prevailing in the region. The temperature dropped significantly during this period, causing the moisture in the air to condense and form fog.
- Temperature Inversions: Another contributing factor was the presence of temperature inversions. Temperature inversions occur when a layer of warm air sits on top of a layer of cool air. This situation prevented the fog from dissipating as the warm air acted as a lid, trapping the cool air and the fog close to the ground.
- High Humidity: The humidity in the region was quite high, which added to the foggy conditions. High humidity means there is an ample amount of moisture in the air, allowing fog to form more easily.
- Absence of Wind: The lack of strong winds during this period prevented the fog from dispersing. Wind helps to disperse fog by moving the air around, but the calm weather prevalent last week allowed the fog to linger for longer durations.
