[RegCNET] RegCNET Digest, Vol 323, Issue 7

[Dr AP DIMRI]

you can calculate vertical integrated moisture using q, u and v from 1000 hPa. I suggest to fix upper level upto 300hPa as most of the q is upto that level.you can do that using model RegCM3 output.

 
Sincerely
Dimri

I used water budget equation which says the change in water contents can be due to advection? terms in the left hand side and that must equal to E-P in the right hand side. The rate of change with time for long period is small and negligible. I integrated the equation vertically from surface pressure up 100? mb. When I did the calculation I got unbalance result, the difference is in order of multiple of 10 even multiple of 100. Any one knows why the water budget not balanced in the model?
