Question

What is the association between the jet stream and a polar vortex?

Answer 1

Answer:

Polar vortex versus polar jet stream

The stronger the winds, the more the air inside is isolated from warmer latitudes, and the colder it gets. When the Arctic polar vortex is especially strong and stable (left globe), it encourages the polar jet stream, down in the troposphere, to shift northward.
