[ferret_users] regarding vertical integrated moisture flux

Dear Ferreters,

I am having a small doubt regarding vertical integration for the computation of vertical integrated moisture flux and the vertical axis is having pressure units.

This is the required formulation for this computation

Moisture flux  = (1/g) * integration (0 to surface pressure) of [ specific humidity * horizontal wind vectors ] * dP.

In my data the vertical axis is in hectaPascal from 300 hPa at k=1 to 1000 hPa at k=8. So if I integrate [ specific humidity * horizontal wind vectors ] vertically, it will integrate from 300 to 1000 hPa, so is it doing this integration using correct dP weights i.e thickness of the pressure levels ?

The command I used for this computation is

let zon=(qm[g=u]*u*(1/9.81))
let mer=(qm[g=u]*v*(1/9.81))

let uvec=zon[k=@din]
let vvec=mer[k=@din]

is it correct ?

regards, saurabh
