140-year simulation experiments compare the Atlantic thermohaline circulation response to increasing CO2 and varying surface water and heat fluxes. The Hadley Centre Coupled Model Version 3 (HadCM3) was used for these experiments, which were intercompared with other models as part of the Coupled Model InterComparison Project. The data originates from model runs performed around 2005.
Use Cases
- Analyzing the relative impact of daily surface water fluxes versus surface heat fluxes on Atlantic thermohaline circulation strength.
- Comparing model responses to a 1% compound annual increase in atmospheric CO2 concentration across multiple simulation runs.
- Investigating climate drift by comparing these flux-perturbation simulations against a 140-year HadCM3 control experiment.
- Assessing the effect of a more sophisticated radiation scheme and new land surface scheme on coupled model behavior.
Strengths
- Simulations have a consistent 140-year duration, allowing for analysis of long-term trends.
- Data was produced for a formal model intercomparison project (CMIP), suggesting standardized outputs.
Limitations
- The exact number of simulation runs, rows, and specific output variables are not provided.
- Data is based on a single climate model (HadCM3), limiting generalizability without the other CMIP model outputs.
