Global Warming Is the Causes of the Polar Vortex

Mon ,26/12/2022

It is difficult to explain how global warming can cause some of the extremely cold weather we have been experiencing. The Arctic is warming much faster than the rest of the earth. The warmer Arctic destabilizes and weakens the jet stream, causing it to pull frigid air down from the Arctic into the United States.

The weaker the jetstream, the slower the loops (called Rossby Waves) move from West to East. This causes the polar vortex pattern to persist longer over the United States. This is like a weather event – and when it will happen is difficult to predict. However, all indications are that we will have many more such events as the Arctic warms.
