The purpose of this exercise was to learn HTML coding, to learn to import JPEG images and to estimate the quasigeostrophic forcing at 500 mb for a baroclinc system over Mississippi. The surface chart to the left shows surface observations and isodrosotherms for the Southern Plains and is an illustration of graphic import from the web.
Warm advection is present in our area and upward forcing is associated.
With this chart the areas of positive vorticity advection correspond with areas of upward forcing and vice versa. Weak positive vorticity advection is found in our area and upward forcing is associated. This used for the Trenberth Approximation . In Mississippi there is weak PIVA and associated weak upward forcing. The area of forcing corresponds to the same area mentioned above.
