Climatology data calculated from global climate model simulations for SRES experiments A1F, A1T, A1a, A2a, A2b, A2c, B1a, B2b.

The climatologies are 30-year averages. Climate anomalies are expressed relative to the period 1961-1990.

The Models.

CCCma: The atmospheric component AGCM2 is a spectral model with triangular truncation at wave no. 32 and 10 vertical levels. The ocean model component based on the GFDL MOM 1.1 code with 29 vertical levels and has a isopycnal / eddy stirring parameterization.

CSIRO: The Mark 2 CSIRO coupled global climate model consists of the atmospheric component which has 9 vertical levels with a R21 horizontal resolution and the ocean component which was based on the GFDL code.

ECHAM4: The model consists of the atmospheric component which based on the weather forecast model of ECMWF. The atmosphere component is the standard model version of a 19-level hybrid sigma-pressure coordinate system. The ocean component is a model which computes with isopycnal coordinates.

GFDL: The atmospheric component solves the primitive equations using a spectral transform method, GFDL_R30 means a rhomboidal 30 truncation and the ocean component solves the primitive equation of motion using the Boussinesq, rigid-lid and hydrostatic approximation and based on GFDL Modular Ocean Model version 1.

HadCM3: The Hadley Centre Circulation Model is a 3-dim AOGCM. The atmospheric component has a 19 levels, the horizontal resolution is comparable with a spectral resolution of T42, while the ocean component has a 20 levels resolution.

NIES: The model developed by the Center for Climate System Resaerch/ National Institute for Enviromental Studies in Tokyo consists of the atmospheric component which has vertical resolution of 20 levels and the triangular truncation at wavenumber 21 (T21). The ocean model has 17 vertical levels and the same resolution. .

The SRES Experiments.

A1B Globalisation with rapid economic growth and a balanced emphasis on all energy sources.

A1T Globalisation with rapid economic growth and an emphasis on non-fossil energy sources.

A1FI Globalisation with rapid economic growth and an emphasis on fossil fuels (Fossil Intensive).

A2 Regionalisation with regionally oriented economic development. A2a, A2b and A2c follow the same experiment design and historic and future forcings but start from different initial conditions.

B1 Globalisation with global environmental sustainability.

B2 Regionalisation with local environmental sustainability. B2a and B2b follow the same experiment design and historic and future forcings but start from different initial conditions.

Notes.

* TAR uses CMIP2 simulations.

* Only two models have run all the experiments.
