Which jet stream migration occurs due to the Ferrel cell transport of temperate air masses poleward?

💡 Explanation

When summer occurs in the Northern Hemisphere, the Ferrel cell enhances northward transport of temperate air, causing a seasonal latitudinal shift of the jet stream associated with the polar front because temperature gradients increase. Therefore, the jet stream migration occurs over North America, rather than other events which depend on different mechanisms and regions.
