700 hPa Height, 900-500 hPa Thickness, and Total RHS QG Omega Equation
Caption: +700 hPa geopotential height (solid contours every 3 dam). +900-500 hPa thickness (dashed contours every 6 dam). +Total RHS of the QG Omega equation [shaded according to the colorbar (10-12 Pa m-2 s-1)]. Warm (cold) colors denote regions of forcing for 700 hPa ascent (descent). +Image was generated from smoothed 1.0x1.0o NCEP-GFS data.
