CFS Seasonal Climate Forecasts
CFS Forecast of Seasonal Climate Anomalies
for
Feb 2010 to
Oct 2010
(Updated: Tue Feb 9 19:38:57 EST 2010)
This page displays seasonal climate anomalies
from the NCEP coupled forecast system model (CFS). Forecasts are from initial conditions of the last 30 days,
with 4 runs from each day. Three ensembles of 40 forecast members are produced.
The 1st ensebmle (E1) is from the earliest 10 days, the 2nd ensemble (E2) from the second earliest 10 days,
and 3rd ensemble (E3) from the latest 10 days. For SST indicies, the ensemble of all 120 forecast members
(Eall) is also produced. E3 has been used as the forecast from the CFS, as it is from the most recent
initial conditions and is expected to be the most accurate statistically. The additional ensembles
(E1, E2, and Eall) can be used to check the forecast consistency. Anomalies are with respect to
1981-2006 hindcast climatology, except for Nino SSTs for which a bias correction with 1981-2006 average
is first applied and then observed climatlogy of 1971-2000 is used to define anomalies.
CAUTION: Seasonal climate anomalies
shown here are not the official NCEP seasonal forecast outlooks.
The NCEP seasonal forecast outlooks can be found at CPC website. Model based seasonal climate anomalies
are one factor based on which NCEP seasonal forecast outlook is
issued.
