<DIV>Could some one help me with a script which can calculate Velocity potential & Divergence from zonal and meridional winds. I want to display Divergence (vector) over Velocity potential (contour) for selected wet years, dry years and for the difference between wet and dry years, and then shade the significant regions (by carrying out a t-test for the difference between the means of wet & dry years).<BR></DIV>
<DIV>Let me thank you in advance.</DIV>
