Dear RegCM users
 
I have run the RegCM3 for investigating the probable SST effects of main water bodies around Iran including Caspian and Mediterranean seas,  Persian Gulf and Oman sea on the monthly precipitation of Iran. For this regards, I changed the SST file to increase all SST of the relevant water body by 1 degree of Centigrade.  But strangly ,there were no changes in monthly mean precipitation of Iran in SST+1 cases. 
 
Any suggesstion is highly appereciated
Thank you in Advance
