An Eddy-Resolving Labrador Sea Modeling Studied by a Coupled Sea Ice-Ocean Circulation Model
نویسندگان
چکیده
Qualitative comparison between observed and simulated fields over the Labrador Sea is performed. The model simulates the observed mean horizontal circulations of the surface cyclonic subpolar gyre and the mid-depth (~ 700 m) cyclonic recirculations. The distribution of the eddy kinetic energy shows good agreement with the observed evidence over the surface in annual average. The model captures the observed typical vortical structures of a pair of vortices and a cluster of vortices offshore West Greenland. For the vertical motion, on the other hand, winter convection reaches about 1000 ~ 1500 m consistent with the observed mixed-layer depth over the Labrador Sea. The model captures the wintertime convection columns.

متن کاملCoupled Sea Ice–Ocean-State Estimation in the Labrador Sea and Baffin Bay
Sea ice variability in the Labrador Sea is of climatic interest because of its relationship to deep convection, mode-water formation, and the North Atlantic atmospheric circulation. Historically, quantifying the relationship between sea ice and ocean variability has been difficult because of in situ observation paucity and technical challenges associated with synthesizing observations with nume...

متن کاملLinkages between atmospheric blocking, sea ice export through Fram Strait and the Atlantic Meridional Overturning Circulation
As a key persistent component of the atmospheric dynamics, the North Atlantic blocking activity has been linked to extreme climatic phenomena in the European sector. It has also been linked to Atlantic multidecadal ocean variability, but its potential links to rapid oceanic changes have not been investigated. Using a global ocean-sea ice model forced with atmospheric reanalysis data, here it is...
متن کاملArctic–North Atlantic Interactions and Multidecadal Variability of the Meridional Overturning Circulation
Analyses of a 500-yr control integration with the non-flux-adjusted coupled atmosphere–sea ice–ocean model ECHAM5/Max-Planck-Institute Ocean Model (MPI-OM) show pronounced multidecadal fluctuations of the Atlantic overturning circulation and the associated meridional heat transport. The period of the oscillations is about 70–80 yr. The low-frequency variability of the meridional overturning cir...
