Hyderabad: The delay in the onset of winter has meteorologists and scientists flummoxed. We are well into the second week of January, yet the mercury level refuses to fall in the city.
An expert from the Indian Institute of Science (IISc) in Bengaluru told Deccan Chronicle: “If there are cold-wave conditions in New Delhi, the cold winds are supposed to reach Hyderabad.” Though Delhi has seen very cold weather, this has not percolated to Hyderabad.
As it turns out, there are other air circulations over the central part of India that are diverting the cold winds from the north and pushing them into the eastern corridor. “Even in Bengaluru the climate is yet to cool down. There has been a change in the pattern of wind-flow that could eventually bring down the temperature in either Karnataka or Telangana. Weird as it may sound, there is rainfall in Chennai. It seems as if the humid winds from the east are meeting with the cold winds of the north over Tamil Nadu, including Chennai,” he said.
He said that the winds from the north are being shunted towards the eastern part of the country, due to the circulation.
“The winter will kick in only post January 10. Until then, we cannot expect any respite from the warm and humid winds from the sea. Vehicular fumes and emissions are just adding to the rise in temperature,” said Raja Rao Boddu, meteorologist (weather forecasting), IMD. “The fumes are creating a barrier of sorts, which is preventing the day-time heat from escaping. Rather it is being radiated back on to the earth.”...
