[gradsusr] A GrADS scripts that calculates moisture convergence

[Teddy Allen]

* This is a script for displaying moisture convergence 
* Written by Michael Maxwell 
*
* rh = Relative Humidity in % 
* t = Temp at *set level in degrees Kelvin
* tc = Temp in degrees C
* td = Dewpoint at *set level in degrees C
* e = Vapor pressure 
* mixr = Mixing ratio
* u = U-wind in m/s
* v = V-wind in m/s
* mconv = moisture convergence/divergence. convergence is positive and 
divergence is negative.
'tc = (t-273.16)'
'td = tc-((14.55+0.114*tc)*(1-0.01*rh) + pow((2.5+0.007*tc)*(1-0.01*rh),3) + 
(15.9+0.117*tc)*pow((1-0.01*rh),14))'
'vapr = 6.112*exp((17.67*td)/(td+243.5))'
'e = vapr*1.001+(lev-100)/900*0.0034'
'mixr = 0.62197*(e/(lev-e))*1000'
'mconv = (-1)*hdivg(u*mixr,v*mixr)*1e4'
'd mconv'

Subject: [gradsusr] A GrADS scripts that calculates moisture convergence


Hi,

I wanted to download a script that calculates moisture convergence from 
ftp://grads.iges.org/grads/scripts/mconv.gs; but I failed due to access 
restrictions imposed here.

Can someone email me this script or the similar or better one? I need it to 
analyse my data to study moisture dynamics.

Thank you in advance for your cordial help.
