GLOBAL TELECOMMUNICATION SYSTEM

ECMWF seasonal sea surface temperature anomaly forecasts on the GTS

Effective December 2004, ECMWF will add the global SST anomaly forecasts from its seasonal prediction system for distribution on the GTS. The anomalies are computed with respect to the model climate for the years 1987 to 2001.

Products will be encoded in GRIB-2 at 2.5 degree lat/lon resolution. They will be inserted on the GTS on the 15^th each month after 12 UTC. Products are monthly averaged SST anomaly fields for each of the 40 members of the seasonal ensemble system, plus the ensemble mean. Details of the bulletin headers can be found on the ECMWF web pages.

These web pages also provide a documentation of the ECMWF seasonal forecasting system together with a wide range of seasonal forecast products in graphical form.

The GRIB-2 encoding and decoding software is available for free downloading.

Note: The convention for T₁T₂A₁A₂ii adopted for these products is specific to the ECMWF and does not fully comply with the allocation of abbreviated headings provided in Attachment II-5 of the Manual on the GTS.
