Notes:
At 250 hPa we do an evaluation of the jets, with the cyclonically curved Polar Jet extending parallel to the 10320-10440 gpm height contour, while the anticyclonically curved Subtropical Jet lies along the 10680 gpm contour. Notice the location of the right exit region of the Polar Jet, over Central Argentina. This is the divergent side of this jet, enhancing upper divergence even more.
