Dear Grads-user,<BR>
I am trying to calculate vertical integrated moisture convergence from our MM5 model output.I have written a script for it.But it is not working.I am getting the picture but it is not the right one.<BR>
<BR>
'open domain3.ctl'<BR>
'set map 1 1 9'<BR>
'set gxout shaded'<BR>
'set t 25'<BR>
'define qu=q*u'<BR>
'define qv=q*v'<BR>
'define qq = -hdivg(qu,qv)'<BR>
'd vint(prs(z=3)/100.,qq,200)'<BR>
Please suggest me to calculate this correctly. I have pressure level MM5 model output with following variables.<BR>
<BR>
ps 0 99 pstar (Pa)<BR>
pslv 0 99 sea level prs (mb)<BR>
u 20 99 u wind (m/s)<BR>
v 20 99 v wind (m/s)<BR>
q 20 99 mixing ratio (kg/kg)<BR>
z 20 99 height AGL (m)<BR>
td 20 99 dewpoint temp (C)<BR>
rh 20 99 rel humidity (%)<BR>
prs 20 99 pressure (Pa)<BR>
<BR>
I am also in doubt which of the above pressure variable should use to calculate moisture convergence.<BR>
Thanking you.<BR>
