The Meteorological Department has predicted a similar spell of severe cold in January. Experts said the state has already seen near sub-zero conditions in previous Januaries.

Reasons behind the extreme cold Snowfall in hill states and frequent Western Disturbances are increasing the impact of winter.

What is a jet stream Weather experts explained that the jet stream is a fast-flowing wind at about 12.6 km above ground. This time, its speed reached nearly 285 kmph.It is active over northern India. Cold winds from the plains and icy winds from the mountains combine, intensifying winter conditions in the state.

Western Disturbances also bring winter rain, known locally as Mavtha.Last year, many districts received rain in January. This year, clouds appeared on the very first day of the month, signalling a similar pattern.
