Scientists to study impact of fog on Bengaluru airport for accurate prediction

Bengaluru, Feb 6: A team of scientists from the state-run Jawaharlal Nehru Centre for Advanced Scientific Research will conduct a 40-month atmospheric study on the impact of fog on the Bengaluru airport operations, said its operator on Monday.

"The study will enable the airport to predict fog conditions more accurately, minimising air traffic congestion," said operator Bangalore International Airport Ltd (BIAL) in a statement here.

The research centre and BIAL signed an agreement to conduct the study with joint funding on atmospheric conditions in the vicinity of the airport at Devanahalli, about 40 km northeast of Bengaluru.

Bharat Ratna, eminent scientist and research centre founder C.N.R. Rao was present on the occasion.

Fog and poor visibility in the morning hours disrupt arrivals and departures of about 200 domestic and overseas flights at the country's third busiest airport during the winter, causing delays, diversions and re-schedules.

"The outcome will be a relief for passengers, flying in and out of Bengaluru during the winter months, when fog is at its peak," said the statement.

The team, led by Professor Sreenivas, will develop a numerical simulation tool capable of predicting onset, intensity and dissipation of fog.

"Factors influencing the occurrence of fog, such as atmospheric variability, ground temperature, atmospheric aerosol loading, radiative fluxes, water vapour and energy transport in the surface layer will be monitored during the fog season and the preceding months," said the statement.

To ensure accuracy of the study, specific instruments, including a wind cube, humidity temperature profiler, net radiation meters, total sky scanner, data acquisition switches and velocity and temperature probes will be set up at designated areas in the vicinity of the airport runway.

"We pursue scientific research and have capabilities to support the airport operator in this exercise to benefit air travellers and airlines," said the Centre's President Nagaraja.

Fog-related delays and diversions inconvenience passengers during the fall season and cause financial losses to the stake holders. "We believe the study will generate data to facilitate flight planning and scheduling, bringing relief to passengers," said BIAL Chief Executive Hari Marar.

The greenfield airport will open its second runway in October for better operations. It will be Category-3 compliant with an advanced navigation system to land and take-off even under heavy fog.

"As fog will still affect operations, its prediction will enable an aircraft to operate under low-visibility conditions," said Marar.

As a deemed university, the city-based Nehru Centre has over 300 graduate students and experimental, computational and infrastructure facilities and 50 faculty members to do inter-disciplinary research.

The decade-old Kempegowda or Bengaluru airport is run by a consortium of private and public partners, including the state and central governments, with 26 per cent combined stake and the balance 74 per cent by private investors.

New Delhi, Jul 21: A 42-year-old contractual doctor, who was working with Delhi government's National Health Mission, passed away yesterday due to covid-19.

Dr Javed Ali had been on the frontline in the fight against the highly contagious illness since March. He tested positive for coronavirus on June 24 and was hospitalised for treatment over the next three weeks.

For the last 10 days, he was on a ventilator. Yesterday morning, Dr Ali breathed his last at the AIIMS trauma centre. He is survived by his wife and two children - a six-year-old son and a 12-year-old daughter.

"I am proud of my husband. He kept working till the end and he is a martyr. He did not take even one day off since March. He worked even on Eid," Dr Heena Kausar, his wife, told media persons.

The cost for the initial treatment at the private hospital was also borne by the family. "No treatment cost was covered when he was at a private hospital initially. We spent around Rs 6 lakh from our own pockets," she said.

Bengaluru, Jul 1: The Meteorological Department has issued a yellow alert and forecasted heavy rains for three coastal districts and 12 more in the south interior Karnataka region, an official said on Tuesday afternoon.

"Thunderstorm with lightning is likely to occur at isolated places over south interior Karnataka from Tuesday to Wednesday," said a Met official.

For Bengaluru city, the Met department has forecast a generally cloudy sky with light rain for the next three days.

Coastal Karnataka -- Dakshina Kannada, Udupi and Uttara Kannada districts have been issued a yellow alert for the next two days with thundershowers and gusty winds.

Winds blowing at speed of 40-50 km per hour are expected on the coast and the Met department warned fishermen against venturing into the sea.

Meanwhile, heavy showers on Sunday night in Vijayapura district gave rise to flash floods in the Doni river and Sogali stream.

An overflowing Doni river submerged the Talikote - Hadaginal bridge, a remnant from the colonial era, and also submerged some agricultural lands. Only recently, these agricultural lands were sown with toor dal plants.

Similarly, many SSLC students also struggled to cross the bridge to reach their examination centres on Monday.

Many houses were also flooded due to the rainfall at Nalatwad and Talikote taluk. Muddebihal, Basavana Bagewadi and Sindagi taluks also witnessed heavy rainfall.

A 40-year-old farmer from Dharwad district was washed away in the Tuppari Halla stream, which is prone to flood during the monsoon season.

Likewise, a truck carrying cotton also got washed away in a stream in Yadgir district.

"There is an offshore trough and a circulation, because of which rain will continue in the coastal area. Only Malnad has not got sufficient rain this year. Probably after two days, Malnad may get some rains," Karnataka State Natural Disaster Monitoring Centre (KSNDMC) Director Srinivas Reddy said. Otherwise, entire state got normal rainfall, said Reddy, though it is not active over Malnad.
