[Bldg-sim] City Climate Model

[M F A Ramadan]

Hello everybody:

Has any one experienced, used or heard about softwares that can run complete
mesoscale climate models!!
(i.e. fluid thermodynaimcs, water content, vegetation, built environment,
....etc). 
I wonder what a great, powerfull and superior creator who can operate such huge
issues in reality whilst We may spend days running only a small detailed
microscale climate simulation !! 

However, any guide would be appreciated.


Thanks,
Mohamad.
