divergence_of_surface_downward_stress 1 [UUUU] The divergence is a signed scalar that represents the magnitude of the 2D surface wind downward stress vector field's source (positive) or sink (negative) at a given point. The surface called "surface" means the lower boundary of the atmosphere. "Downward" indicates a downward flux of momentum, which accelerates the lower medium along the vector and the upper medium against the vector. The surface downward stress is the wind stress on the surface.
