Polar vortex and Tasmanian weather

I made a movie (below) of the polar vortexes using snippets from earth.nullschool.net

It uses all the available years from the nullschool website.

The northern hemisphere vortex has changed the most in recent years, as has northern weather.

As climate change affects the southern hemisphere, changes in the vortex and jetstream may influence Tasmanian weather.

For example, Tasmania may get polar blasts, more extreme rain events, and extended heat waves, as the vortex breaks down.

The vortex has had a stabilising effect on weather as it moves things along. Uncertainties lay ahead.

There are some good analytic videos on YouTube about the jetstream.

My video simply depicts the annual vortex over time, make of it what you will.
