摘要: Deep convection in the Labrador Sea is confined within a small region southwest part of basin. The strength deep this related to local atmospheric and ocean characteristics, which favor processes preconditioning intense air-sea exchange during winter season. In study, we explored effect eddy-induced flux transport on stratification properties convection. Simulations from an eddy-resolving model are presented for Sea. general circulation was well simulated by model, including seasonal cycle Current. distribution surface eddy kinetic energy also close that derived Topex-Poseidon satellite altimeter data, but with smaller magnitude. transfer diagnostics indicated Irminger rings generated both baroclinic barotropic processes; however, when they propagate into interior basin, process disperses them converting mean flow. contrast eddy-permitting simulations, better represented regarding their lateral position. Further analysis improvement might be due associated resolved contributes realistic position isopycnal dome correspondingly site
