The Jet Stream

Are there any (moving) charts that just show the Jet Stream (ideally all the way around the world) in real time and historically?

A few here. Some not animated .

Another one based on the GFS

Also, the Earth site shows the jet stream model if you set the pressure altitude to 250 HPa, like this.

thanks,but that confuses me .HPa is not a measure of height is it?

The altitude at which pressure is 250 hpa, AFAIK

That makes sense (a nice feature)

The way the computer models work, they don't display pressure directly but rather the altitude at which the pressure is a certain number. The result is almost the same. The maps don't explicitly try to show the jet stream, but that altitude is where it tends to be - which can mean gaps in the chart where the jet stream deviates out of the chart range. (The Meteociel "jet stream" map is doing the same but at a slightly lower altitude).
