HELP! - deterministic vs ens mean


icebreaker5221

Recommended Posts

Hello meteorological community,

 

I think it's pretty common knowledge that the ensemble mean forecast outperforms the deterministic, on average, during the 7-10 (or 7-14) day range.  This appears to be true for both the GFS/GEFS and the ECMWF/ECME, and probably many others. 

 

Does anyone know any peer-reviewed papers that demonstrate this to be true?  I know I've seen at least one of them before that focuses on 500 mb heights but cannot find it right now. 

 

Much appreciated!!!
