    Description: The Weddell Sea polynya is a large opening in the open-ocean sea ice cover associated with intense deep convection in the ocean. A necessary condition to form and maintain a polynya is the presence of a strong subsurface heat reservoir. This study investigates the processes that control the stratification and hence the buildup of the subsurface heat reservoir in the Weddell Sea. To do so, a climate model run for 200 years under preindustrial forcing with two eddying resolutions in the ocean (0.25° CM2.5 and 0.10° CM2.6) is investigated. Over the course of the simulation, CM2.6 develops two polynyas in the Weddell Sea, while CM2.5 exhibits quasi-continuous deep convection but no polynyas, exemplifying that deep convection is not a sufficient condition for a polynya to occur. CM2.5 features a weaker subsurface heat reservoir than CM2.6 owing to weak stratification associated with episodes of gravitational instability and enhanced vertical mixing of heat, resulting in an erosion of the reservoir. In contrast, in CM2.6, the water column is more stably stratified, allowing the subsurface heat reservoir to build up. The enhanced stratification in CM2.6 arises from its refined horizontal grid spacing and resolution of topography, which allows, in particular, a better representation of the restratifying effect by transient mesoscale eddies and of the overflows of dense waters along the continental slope.

    Historical (1985-2015) Fram Strait volume, heat, and salt transports in CMIP6 models (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: This Dataset contains Fram Strait volume, heat, and salt transport calculations for one ensemble member of each of 13 climate models participating in the Coupled Model Intercomparison Project phase 6 (CMIP6). The 13 models are BCC-CSM2-MR, CAMS-CSM1-0, CanESM5, CESM2, EC-Earth3, GFDL-CM4, GISS-E2-1-H, IPSL-CM6A-LR, MIROC6, MPI-ESM1-2-HR, MRI-ESM2-0, NorESM2-LM, and UKESM1-0-LL. For each model, transports are provided along a depth vs longitude section at monthly resolution over years 1985-2015 of the CMIP6 historical simulation. All transports are provided on the models' native grids except for GISS-E2-1-H and NorESM2-LM. The data are stored in netcdf format with metadata in each file including the variant label of the ensemble member and model-specific constants used for the transport calculations.
