Climatology and variability in the ECHO coupled GCM
ECHO is a new global coupled ocean‐atmosphere general circulation model (GCM), consisting of the Hamburg version of the European Centre atmospheric GCM (ECHAM) and the Hamburg Primitive Equation ocean GCM (HOPE). We performed a 20‐year integration with ECHO. Climate drift is significant, but typical...
