Left Exit RegionUsed interchangably with Left Front Quadrant; the area downstream from and to the left of an upper-level jet max (as would be viewed looking along the direction of flow).
This divergence results in upward motion of air in the right rear quadrant (or right entrance region) of the jet max. Severe weather potential sometimes increases in this area as a result. See also exit region, left exit region.
Right Entrance RegionUsed 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).
Entrance Region - The region upstream from a wind speed maximum in a jet stream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
The region upstream from a wind speed maximum in a jet stream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
Exit Region The region downstream from a wind speed maximum in a jet stream (jet max), in which air is moving away from the region of maximum winds, and therefore is decelerating.
Jet Max: The area of max wind speed within the jet stream.
Jet Winds: Also know as the "Jet Stream" are areas of winds 50 to 300 mph plus that appear in the atmosphere at 18,000 to 50,000 feet.
They maybe 500 to 3,000 miles long.

Left Front Quadrant (or Left Exit Region): The area downstream from and to the left of an upper-level jet max (as would be viewed looking along the direction of flow).
Used interchangably with Left Exit Region; the area downstream from and to the left of an upper-level jet max (as would be viewed looking along the direction of flow).
Jet Streak - Same as Jet Max; a point or area ("streak") of relative maximum wind speeds within a jet stream. Jet streaks can often enhance foul weather conditions at the surface.
arrows) are much smaller in the blue regions, where the winds are relatively weak, and largest in the red, which is the region of strongest winds. The ribbon of strongest winds (green, yellow and red colors) is called the jet stream with a jet ...
JETMAX - A local wind speed maximum in a jet stream. Vertical wind shear increases abruptly beneath the jet max. Also called JET CORE.
