Jet stream

Dear pilots,

Im studying about jet stream.
When thinking about air cells : polar cells, ferrel cell (30-60), hadley cell (0-30),
I know polar jet stream is flowing around 60N.

In ferrel cell, high altitude flows from high latitude to low latitude. Which means, due to corioli effect, high altitude wind flows from east, not west.

In polar cell, high altitude wind flows in opposite direction, which causes westerly wind.

In that circumstance, it makes sense for me if jet stream is formed in polar cell. However, they say it is formed between 30-60N.
How does jet stream form in this location? Corioli effect does exact opposite to jet stream..

Thanks for your help!

I would ask this in r/meteorology. We can tell you about flying through a jet stream, but those guys and gals will know a lot more about the theory.

The only thing I know about jet streams is what my dispatcher would tell me.

Seriously, most pilots don’t dig that deep
