Abstract

The Thermohaline Circulation simulation dataset was produced to investigate the response of the HadCM3 model to a suppression of the thermohaline circulation in the Atlantic Ocean. The suppression was induced by a strong initial perturbation to the salinity distribution in the upper layer of the northern North Atlantic. The model was then allowed to adjust freely.

The Thermohaline Circulation simulation data contained in this dataset were used to investigate the response of HadCM3 to a significant increase in the freshwater influx to the ocean thus weaking the thermohaline circulation. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.

Data members run for this experiment: abpsp

Boundary conditions: Fixed forcing representative of late nineteenth century conditions as per the HadCM3 control run.

Initial conditions: The model was initialised using the conditions from 1991 of the HadCM3 control run. These conditions were perturbed by producing a weakened thermohaline circulation in the model. This was achieved by replacing the salinity field in the top 800m of the northern North Atlantic [(50-90 degrees N) x (80 degrees W to 20 degrees E)] with a vertical profile that is much fresher and has a deeper pycnocline. On average the water in the area of the perturbation is made 2 PSU fresher. Assuming a reference salinity of 35 PSU, the area would have to receive a freshwater pulse of about 16 Sv yr to experience this freshening. Conservation of salt was assured by globally redistributing the salt taken out of the North Atlantic, increasing salinity everywhere by about 0.01 PSU. The model was allowed to adjust freely to the new salinity field.

More detailed metadata on the model configuration and parameters is available in XML format.

Title	Hadley Centre Hadley Centre Coupled Model Version 3
Abstract	The Hadley Centre Hadley Centre Coupled Model Version 3 was developed from the earlier HadCM2 model in the period 1997-2000. Various improvements were applied to the 19 level atmosphere model and the 20 level ocean model and as a result the model requires no artificial flux adjustments to prevent excessive climate drift. The atmosphere and ocean exchange information once per day, heat and water fluxes being conserved exactly. The main differences from the previous HadCM2 model are a significantly more sophisticated radiation scheme; the inclusion of the direct impact of convection on momentum; and the inclusion of a new land surface scheme that includes a better representation of evaporation, freezing and melting of soil moisture. It improved on the resolution available from previous Hadley Centre models and included support for interactive couplings between the atmosphere and ocean and the biosphere, atmospheric chemistry, the sulphur cycle and atmospheric aerosols. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.
