Scattered rains occurred over Delhi and adjoining regions on December 11. December 13 onwards winds moderate northwesterly winds in the range of 15 to 20 kmph have been blowing over the region. Due to these cold and dry winds, the temperatures dropped and fog was not able to set in due to the high speed of winds.
However, in the last 24 hours, the wind speed has decreased significantly due to the approach of a fresh Western Disturbance over Jammu and Kashmir. As per Skymet Weather, during late night hours and early morning hour’s winds become calm to very light.
For the formation of fog, the three criteria’s such as low temperatures, high humidity, and light winds are necessary. Due to a significant decrease in the wind speed, these idle conditions for fog formation have occurred once again.
