1 AbstractA control run of 150 years for CCSM2 has been performed at the NorwegianMeteorological Institute. In this run the external forcing(especiallyradiation) were held constant, CO2 were held at the level of 1990. CO2 in-fiences only the atmosphere and the the carbon cycle between ocean andatmosphere is not included. Both ocean, ice, and atmosphere will varyas a function of time in this run, although we might not be able to compare model data directly with the observed data, it is however possible to observe variations in atmospheric climate, extension of the SST, ocean circulation,and ocean hydrography(which is the most common type of datathat we have, both modern as well as paleo data).What we are most interestedin is to investigate the role of the meridional ocean circulation in thissystem, as variations of it often is used as a measure of the role the oceancirculation might have in this system.The survey should be started on a more global scale and should thereafterbe expanded to a smaller scale, which means of dividing this up intoboxes. In this document we will especially focus ourselves on the subtropicaland mid-latitude part of the Atlantic sector, where the meridionalcirculation and heat transport is the greatest. We will be considering thefollowing: SST, SSS Mean Ocean temperature Mean Salinity Comparisons of temperature for Lev/POP Temperature Anomalies SST Anomalies Volume and Heat transports.
