i want to compute the vertically integrated moisture transport over lon (25W - 15E) <br>and lat (0 - 20N) at selected years (say 1994,1999,2003 and 2008 from NCEP monthly)<br>using this script i saw online from you;
'sdfopen file-pressure.nc'
'sdfopen file-zonal-wind.nc'
'sdfopen file-meridional-wind.nc'
'define QiJAN=ave(vint(pr<span style="color: rgb(255, 0, 127);">msl</span>.1(z=1)/100,<span style="color: rgb(0, 127, 64);">shum</span>.1*uwnd.2,200),t=((t=181)+(t=241)+(t=289)+(t=349))'
'define QjJAN=ave(vint(pr<span style="color: rgb(255, 0, 0);">msl</span>.1(z=1)/100,<span style="color: rgb(0, 127, 64);">shum</span>.1*vwnd.3,200),t=((t=181)+(t=241)+(t=289)+(t=349))'
'set gxout vector'
'd QiJAN;QjJAN'
but i dont get some details from the script-<br>1. is msl the pressure data?<br>2. is shum the specific humidity?<br>3. will my time be the problem with the script?<br><br>Thanks in anticipation.<br><br>ugo okoro<br>cmsr, iap-cas,<br>beijing<br></pre><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: monospace; background-color: transparent; font-style: normal;"> <blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; margin-top: 5px; padding-left: 5px;"><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> </div> </blockquote></div> </div></body></html>
