CFS Seasonal Climate Forecasts
CFS Forecast of Seasonal Climate Anomalies
for
Oct 2012 to
Jun 2013 (Updated: Mon Sep 24 12:04:09 EDT 2012)
CFS version 1 will be discontinued after October 2012.
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. Forecast ensembles consist of 40 members from
initial a period of 10 days. 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. Aomalies are with respect to 1981-2008 hindcast climatology. Temporal correlations based on
1981-2006 hindcasts and observations are used as skill mask for spatial anomalies.
Standard deviation to normalize anomalies is the average standard deviation of individual
members computed from 1981-2006 hindcasts for the corresponding initial month and target
seasons. You may also want to check the
parallel forecast display for CFS version 2 (CFSv2).
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.
