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.
Units: kPa m-1 s-1
