摘要: The strong, mesoscale tip jets and barrier winds that occur off the coast of southeastern Greenland drive large surface turbulent heat fluxes may impact deep ocean convection. wind stress curl associated with 10 m patterns identified using self-organizing map technique are investigated for winters (1997–2007, November-December-January-February-March) in European Centre Medium-Range Weather Forecasts Interim Reanalysis (ERA-I) a regional simulation Research Forecasting (WRF) model at 50 km. Sensible flux differences between WRF ERA-I primarily due to near-surface temperature, while latent driven by both moisture speed differences. largest over marginal ice zone where larger than specified sea thickness influences atmospheric temperature moisture; has magnitude Irminger Sea. Patterns strong westerly jet flow most likely preconditioning convection Sea compared other manifestations jets, easterly expected have localized impacts south Cape Farewell.
