Plots 1000-500 mb thickness, 1000-500 mb Thermal Wind, and 700 mb absolute vorticity.
Regions of 700 mb vorticity advection by the Thermal Wind indicate rising motion in the
layer. (see this link
for the Trenberth Formulation)
Plots 500 mb height, relative humidities greater than 70%, and RAOB upper air numbers.
The white background of the GIF image is made transparent with imagemagick and then overlayed onto a blank, colored
background image. (still has bugs)
