Dense fog conditions are likely to be delayed in the capital this year,the Met department has said,with the occurrence of three cyclones over the Bay of Bengal and the absence of Western disturbances over northern India delaying the phenomenon.
The spell of fog which usually starts developing over the Indo-Gangetic plains and envelops large parts of northern India by mid-December,disrupting flight and train schedules is not likely to arrive before December.
According to the Met department,a moderate fog cover envelops the capital in the first 10 days of December. From mid-December,it intensifies into dense fog,covering large parts of northern India.
Last year,the fog spell started around December 12 and covered the entire Indo-Gangetic plains by December 23. But so far this year,fog conditions are yet to develop.
The delay has been caused because of the three cyclones Helen,Lehar and Madi that occurred over the Bay of Bengal, R K Jenamani,director of the Indira Gandhi International Airports Met department,said.
The cyclones caused strong westerly winds to blow across the plains,which is also one of the reasons why winter has been delayed this year,and we are still getting clear skies and a higher day temperature. On Thursday morning,not a single airport across the region reported even shallow fog conditions, Jenamani said.
The winter pattern is unlikely to recover fast as there is still no likelihood of any major Western disturbances, Jenamani said. The weatherman said strong winds on Thursday over most parts of north-western India were unlikely to subside in the next two days,delaying the formation of dense fog.
