Why Is Global Warming Disrupting the Polar Vortex? Could North India Face Harsher Winters? | Skymet Podcast EP-61

In this episode of the Skymet Podcast, AVM (Retd.) G.P. Sharma, President – Meteorology & Climate Change at Skymet, explains the science behind the Polar Vortex in clear and simple terms.

The Polar Vortex is a powerful circulation of extremely cold air and low pressure that typically remains confined over the North and South Poles. However, when this system weakens or becomes unstable, cold air can spill southwards—triggering sudden cold waves, snowfall, and extreme winter conditions across Canada, the United States, Europe, and at times North India.

The episode explores the role of the jet stream, atmospheric layers, and global warming in influencing the behaviour of the Polar Vortex. With ongoing climate change, the vortex is becoming increasingly irregular and unpredictable, making winter weather more volatile across the globe.
