MeT helps IGI see through dense fog spell

Dense fog haunting the Delhi airport even in February, this fog season is turning out to be one of the worst in more than two decades. In fact, it already is the third worst fog season since 1996.

“This whole season has seen long dense fog hours and it is the third worst fog season in the last 20 years. With two days of very dense fog already experienced in February, it might end up to be one of the worst,” said R.K. Jenamani, the Director-in-Charge of the Meteorological Department at the Indira Gandhi International Airport here.

Dense fog made a rather late entry this winter, with December not witnessing long dense fog hours. However, January more than made up for it with 429 hours of fog, including 24-hour long dense fog cover on some occasions. A total of 750 fog hours were witnessed in December 2015 and January 2016, the third-highest since 1996.

Despite the record number of fog hours, flight disruptions this winter were comparatively painless compared to the previous few winter seasons.

The most significant marker of this trend was the rather low number of flight diversions and cancellations this time. A high number of diversions take place due to sudden onset of fog, which takes airlines by surprise.
