Divergent and Rotational Wind Components
wind_1.ncl: First calculates
divergence, then the divergent wind components. Creates a simple
vector plot.
uv2dvG calculates the divergence. Note that no attributes or coordinates variables exist for div.
dv2uvg calculates the divergent wind components.
wind_2.ncl: First calculates vorticity
and then the rotational wind components. Creates a simple vector plot.
uv2vrG computes the vorticity.
vr2uvg computes the rotational wind components.
