Abstract

This study analyzes the predictivity of convection depth in the Labrador Sea based on data from the period 1992-2003 - floats, moorings, hydrographic sections, satellites and ice cover data. We show that taking into account atmospheric forcing observations, lateral fluxes and knowledge about prevailing stratification in this convection area in late summer we can infer convection depth the following winter with good accuracy. The relevance of the parameters for prediction of stratification in late summer is analyzed. Previous convection events, atmospheric forcing and eddy activity influence stratification locally. Remotely, the major variable appears to be the West Greenland Current with its upstream sea ice melt. It is possible to predict the central Labrador Sea stratification with the mentioned parameters reasonably well. This makes it possible to analyze the relevance of these remote parameters for prediction of convection depth, showing the importance of the West Greenland Current.
