[gradsusr] how to find out vertical integration in grads ...

[Kishore Ragi]

Dear Davide,

I know from your explanation that with vint and -hdivg we can calculate
VIMFC ( vertically integrated moisture flux) but, I have a doubt if vint
function includes the reciprocal of gravitational force (g=9.81)..



d vint(const(ps,1000),-hdivg(u*qv,v*qv),100)),

where u,v are horizontal wind fields and qv is mixing ratio.

Does above code enough or I should input g term too?

Thank you for the clarification ...

Regards,

Kishore
