Fog-hit Delhi airport gets help from Pune scientists

New Delhi: As the Delhi airport braces for another season of fog, it has started receiving help from scientists at the Pune-based Indian Institute of Tropical Meteorology (IITM) to predict visibility levels at least a day in advance.
The airport currently has advance visibility information of about four-five hours. A new forecast model developed by IITM scientists in the last couple of years has enabled scientists to predict visibility levels between 12-24 hours in advance.
IITM started sharing this information with the Delhi airport, on an experimental basis, on November 30. Sachin Ghude, one of the researchers on the Winter Fog Experiment (WIFEX) project that has developed the new forecast model, said that so far, the predictions have matched with the observed data. The visibility has not gone below 400-500 metres in the last few days.
A weather forecaster at the Delhi airport said they are in the process of “evaluating IITM’s improved model” of fog forecasting. He said a major fog event at the airport is unlikely before December 10. In the wake of major disruptions in flight schedules caused by fog in the last few years, scientists have been working on developing a reliable fog forecasting technology.
