Skill of the 5-day Forecast for 2007

 5-day forecasts, 4xdaily, 365 day

 ALL vs. noTAO

 Anomaly w.r.t 30-year 6-hr climatology (R2, 1981–2010)

Day Day ALL (global)

noTAO (global) ALL (TPcf) noTAO (TPcf)

Global: AC calculated over all grid points TPcf: AC calculated over tropical Pacific domain (150oE–90oW, 20oS–20oN)

Systematic errors in the R2 model:

A comparison between first guess (ft06) and BUFR OBS (A topic suggested by Wesley)

 OBS: AIRCFT and AIRCAR

 Variables: T, U, V between 200 and 300 hPa

 Mean bias averaged over 3 years (2004, 2005, 2006)

Purposes

 Global and regional evaluation of the R2 model

 Understand model errors in mean state and variability

 Improve model representations of the related physical processes (convection, clouds, radiation, precipitation)

(12)

Large number of OBS over the US

(13)

Overall cold bias over the US

(14)

Positive bias over the central US

(15)

Positive bias over the western US
