Question

What causes cold waves in Northern India during winter?​

Answer 1

“Dense fog is the main cause for the cold,” said R.K. Jenamani, a meteorologist with the national weather forecasting center. He attributed the weather's severity to storms in the Mediterranean that have caused sudden winter rain in northern India, a phenomenon known as a “western disturbance.”

Answer 2

I think this would be your answer!.

Step-by-step explanation:

During the winter months, the passage of western disturbances causes "dry, cold north-westerly winds" to blow into north and central India, causing minimum temperatures to plummet over these areas, resulting in cold-wave conditions.
