NEW DELHI,


The Arctic winds are pushing various weather systems, including the western disturbance, downwards. It has indirectly resulted in severe and extended winters, said Mahesh Palawat, vice president of Meteorology of Skymet


THE unusually cold weather in the hill states of North India and parts of the plains, including the national capital, has been indirectly caused by the Polar Vortex that usually spins over the North Pole and is currently sweeping across large parts of the US and Canada that is pushing various weather systems downwards, experts say. “There is no direct relation between the Polar Vortex and Indian weather but the Arctic winds are pushing various weather systems, including the western disturbance, downwards. It has indirectly resulted in severe and extended winters.


The intensity and frequency of western disturbance have also increased,” Mahesh Palawat, vice president of Meteorology and Climate Change at private forecaster Skymet, told IANS, adding that this would continue toll mid-February. Noting that frequency and intensity of the western disturbances (WDs) were very high this time around, he said India has already witnessed six such instances so far which  have resulted in heavy to moderate snowfall.


“One more will come this week and more snowfall is expected. Usually, the disturbance started moving to upper latitudes by January-end. But this time, due to the western disturbance, the temperature in Rajasthan, MP, Maharashtra and Telangana has also gone down. “This can be considered as the indirect effect of Polar Vortex. The cold will continue till mid-February,” Palawat added. The coldest place in the Valley this winter, as in the past, was Kargil at minus 16 degrees Celsius.
