Weather News: Northern India has been experiencing unusually cold weather in January following dense fog and frequent rains.

Delhi and other parts of northern India including Punjab, Haryana and Uttar Pradesh are reeling under severe cold conditions. Over the last few days, people have been witnessing cold days.

Also, no respite is expected until this weekend, as the India Meteorological Department (IMD) has forecast rain, fog and low temperatures in the coming days.

Experts previously warned of extreme cold due to La Nina, a weather phenomenon in the Pacific Ocean that causes temperatures to drop.

But why is North India reeling under severe cold conditions?
