I have horizontal wind fields u(time,level,lat,lon) and v on a fixed grid.
(15S to 15N ; 40E to 160E). I computed the horizontal wind divergence using
the following three functions:

1) div=uv2dvF(u,v)
2) div1=uv2dv_cfd(u,v,lat,lon,2)
3) div2=

Is there any reason why, the above values would not be approximately equal?
My divergence values differ from each other by at least one order of
