[gradsusr] vertically integrated moisture flux

[Mario Caffera]

Thank you Tere. That was the way I calculated early. 
But like thies, there is a lack of moist from surface to 1000hPa, in the cases when surface pressure is higher than 1000. Otherwise I guess it could be some problems by the fact of having constant pressure files in one side, and surface files apart. That is puzzling me.

    Hi,

     

    Another way to calculate

    Vertically integarted moisture flux convergence (VIMFC)

    from 1000mb to 100mb:

    

    sdfopen shum.nc

    sdfopen uwnd.nc

    sdfopen vwnd.nc

    

    set lon x1 x2

    set lat y1 y2

    set t 1 T

    set lev 1

    qu=vint(1000,shum.1*uwnd.2,100)

    qv=vint(1000,shum.1*vwnd.3,100)

    vimf=-hdivg(qu,qv)

    d vimf

    

    Best,

    Tereza Cavazos

        dear friends 

        
        you can use the script to calculate qu component and adjust
          for qv comonent for vertically integrated moisture flux vector
          between 1000 and 300 hpa levels
