1 Abstract
A control run of 150 years for CCSM2 has been performed at the Norwegian
Meteorological Institute. In this run the external forcing(especially
radiation) were held constant, CO2 were held at the level of 1990. CO2 in-fiences only the atmosphere and the the carbon cycle between ocean and
atmosphere is not included. Both ocean, ice, and atmosphere will vary
as 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 data
that we have, both modern as well as paleo data).What we are most interested
in is to investigate the role of the meridional ocean circulation in this
system, as variations of it often is used as a measure of the role the ocean
circulation might have in this system.
The survey should be started on a more global scale and should thereafter
be expanded to a smaller scale, which means of dividing this up into
boxes. In this document we will especially focus ourselves on the subtropical
and mid-latitude part of the Atlantic sector, where the meridional
circulation and heat transport is the greatest. We will be considering the
following:
SST, SSS
Mean Ocean temperature
Mean Salinity
Comparisons of temperature for Lev/POP
Temperature Anomalies
SST Anomalies
Volume and Heat transports.
