Coupled Toga Models at the Ukmo
Both general circulation (GCM) and intermediate ocean and atmosphere models are being used by the tropical ocean modelling group at the UK Meteorological Office to investigate interannual variability. A 13-year coupled GCM integration was completed in 1990, producing a realistic seasonal cycle but little interannual variability. Some details of year 8 of that integration are presented here, and a related hindcast experiment is discussed. An intermediate model with two active layers in the ocean and an equilibrium atmosphere is described: ocean climatology and preliminary coupled experiments are discussed.
