Cyclogenesis associated with right and left entrance/exit regions of a jet streak

Types of Cyclogenesis

Right entrance of a Jet
On the warm side of the jet core, in the region of maximum acceleration of flow. Often associated with marked cyclogenesis.

Right Entrance Region
Used interchangably with Right Rear Quadrant; the area upstream from and to the right of an upper-level jet max (as would be viewed looking along the direction of flow). Upward motion and severe thunderstorm potential sometimes are increased in this area relative to the wind speed maximum.
