WMO has a new flagship product, Global Seasonal Climate Update (GSCU), which has been developed building upon the success of the WMO El Niño/La Niña Updates for over more than a decade. The GSCU summarizes the current status and expected future behavior of seasonal climate in terms of major general circulation features and large-scale oceanic anomalies around the globe (e.g., ENSO, NAO, IOD, etc.), and discusses briefly their likely impacts on continental scale temperature and precipitation patterns. The GSCU comprises two parts, the Update and supplementary information document.
The latest Update is the October Update.
More Updates and supplementary information can be downloaded from the CPC ftp server.
