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.

wind_3.ncl: Divergent wind vectors plotted over velocity potential.

wind_4.ncl: A black and white version of example 4, suitable for publication.
