Mesoscale Variability in the Labrador Sea
The objective of this study was to understand the interaction between deep convection in the Labrador Sea and mesoscale eddies, in order to quantify the influence of convective events on the large-scale circulation. Three- dimensional non-hydrostatic numerical simulations were used to examine the re...
