A Global Ocean-Atmosphere Climate Model. Part II. The Oceanic Circulation
Global Ocean-Atmosphere Climate Oceanic Circulation
2009/3/24
A numerical experiment has been carried out with a joint model of the ocean and atmosphere. The 12-level model of the world ocean predicts the fields of horizontal velocity, temperature and salinity. ...
A Global Ocean-Atmosphere Climate Model. Part I. The Atmospheric Circulation
Geophysical Fluid Dynamics Laboratory Atmospheric Circulation Global Ocean-Atmosphere Climate
2009/3/24
A joint ocean-atmosphere model covering the entire globe has been constructed at the Geophysical Fluid Dynamics Laboratory (GFDL) of NOAA. This model differs from the earlier version of the joint mode...
A Model for the Thermodynamic Growth of Sea Ice in Numerical Investigations of Climate
Thermodynamic Growth Numerical Investigations of Climate Sea Ice
2009/3/7
A model is presented whereby the thickness and extent of sea ice may be predicted in climate simulations. A basic one-dimensional diffusion process is taken to act in the ice, with modifications due t...
Atmosphere-Ocean Mechanisms of Climate Anomalies in the Angola-Tropical Atlantic Sector
sea surface temperature Atmosphere-Ocean Mechanisms Angola-Tropical Atlantic Sector
2009/2/5
Interannual variations in the large-scale atmospheric and oceanic fields over the tropical Atlantic are studied in relation to rainfall anomalies on the Angola coast. Departure patterns are constructe...
