Polar Jet Stream Flow: Counter-Clockwise Around Earth

[pwn01]

Why does the polar jet stream flow counter-clockwise around the Earth (as viewed from the north pole)? It seems that since the air at the north end of the Ferrel Cell and the south end of the Polar Cell rises, the Coriolis effect would cause a circulation in the clockwise direction.

Air moving toward the poles is pushed Eastward by the Coriolis Force.

I've seen diagrams that show the polar jet as actually residing in the upper northern part of the Ferrel Cell rather than the upper southern part of the Polar cell. In other words it forms in the region that the circulation begins to turn southward after rising. I can see that there is a more pole-ward direction of the rising air in the southern part of the Polar Cell. What am I not understanding?

What am I not understanding?

I'm not entirely sure. Isn't the northern part of the Ferrel cell turning eastward, as any north-moving air mass is won't to do under Coriolis Force?

I see what you are saying. I guess that since the polar jet is not near ground level, I assumed that the circulation had already risen and reversed direction returning southward.
