Thank you for
your profound email. But my query is still no resolved and I
having confusion for the calculation of vertically integrated
moisture flux and its divergence over the data levels of
(1000, 925, 800, 700, 600, 500, 400, 300). I have 3 results
for divergence of vertically integrated moisture flux that I
computed using NCEP and ERA-Interim and according to my
understanding its unit is (kg/m^2/s) which is equivalent to
(mm/day). Then I compared this computed result form
ERA-Interim provided data for divergence of vertically
integrated moisture flux and I found that my computed result
is 2 order less than this.
I am attaching
figures and my script for this computation. I am trying hard
to understand why it is so but absolutely clueless about this.
