[RegCNET] Re: ECHAM Runs

[Dr. Md. Nazrul Islam]

Hi Jeremy and Faisal,
It seems that ECHAM result of RegCM is beeter than that we obtained using 
Grell-AS/FC. For your kind information, PRECIS results are included with 
Faisal's monthly and seasonal values. In my openion, both model detected 
well the precipitation band (i) through Nepal extended more NW and SE, and 
(ii) Western Ghat of India. Some dissimilarities are (i) in and around 
Shillong hill of India(where Cherapunji, the highest rainfall recorded 
station existed) and (ii) over the Bay of Bengal.

I am looking for the ECHAM version of RegCM and analyzing detail for 
longterm data, we may find better conclusion. 

For your kind information, PRECIS can measure about 92% of surface rain over 
Bangladesh.
