The Q-vector is defined by the following equations:
Q1=-[R/(sigma*p)] *[(du/dx)*dT/dx)+(dv/dx)*(dT/dy)]
Q2=-[R/(sigma*p)] *[(du/dy)*dT/dx)+(dv/dy)*(dT/dy)]
where the partial derivatives were calculated with the use of the cdiff function in GrADS.

The vectors were made by plotting the vector sum of Q1 and Q2 and colored by the magnitude of the resulting vector. Q-vectors are not available at 1000 mb.
