Hi,<br />
Try this.<br />
<br />
open ATM.2005060100.ctl<br />
set dfile 1<br />
define r1=ave(tpr.1,t=1,t=120)*30/10<br />
<br />
open ATM.2005070100.ctl<br />
set dfile 2<br />
define r2=ave(tpr.2,t=1,t=124)*31/10 ....and so on.<br />
<br />
Thanks.<br />

I did the same as you suggested but i am getting the warning messages.<br />
Please have a look on this and give your suggestion.<br />

Hi Rajesh,<br />
Why don't you use the Post Processing tool of RegCM3.<br />
This post processing tool will solve all your query in this mail.<br />
This tool can help you to derive monthly mean of your desired variables and also it can get geopotential height.<br />
<br />
<br />
Anyway, there is some wrong with defining time with your grads script.<br />
You see each CTL file and average the variable as per the number of time stamp available. You can use this example script with slight modification of your script. <br />
<br />
<br />
define r1=ave(tpr.1,t=1,t=120)*30/10<br />
define r2=ave(tpr.2,t=1,t=124)*31/10<br />
define r3=ave(tpr.3,t=1,t=124)*31/10 ....and so on.<br />
<br />
The same method you can apply for wind. Hope this helps you.<br />
<br />
<br />
Thanks.<br />
<br />

>Hello All,<br />
 <br />
 I am plotting monthly and seasonal precipitaion  , circulation field(200,850).<br />
These are the step(Given below) i am following for plot like precipitation and vector wind.<br />
<br />
Let me correct , if i am missing something  for correct plot.<br />
I need help on how to  plot geopotential height(monthly and seasonal) and give the idea(with example) . <br />
Please  help me regarding the above problem.<br />
