Chennai airport flights diverted due to dense fog, visibility improved later, weather experts cite diurnal temperature variation.
A few flights were diverted from the Chennai airport on Saturday morning due to dense fog.
After 6 a.m., the visibility started to dip to 800 m and, by 7 a.m., it dropped to as low as 200 m. The visibility level improved after 8 a.m., and flight operations reverted to normal after 9 a.m. When the visibility was hit, four flights from cities, including Muscat, Pune, and Singapore, were diverted from the airport.
The Regional Meteorological Centre (RMC), Chennai, had recorded moderate to dense fog in Chennai and its neighbourhoods between 7.30 a.m. and 8.30 a.m. on Saturday. Officials said the surplus rainfall and the extended Northeast monsoon had led to excess moisture in the atmosphere. Diurnal temperature variation was one of the reasons cited for radiation fog.
Weather experts said fog in February was less common in Nungambakkam and Meenambakkam. There have been instances of fog formation in Coimbatore in February too. However, it was rare. The RMC has predicted the possibility of mist or haze cover at isolated pockets in Tamil Nadu and Puducherry during the morning hours for two days.
