Atmospheric Forcing of Ocean Convection in the Labrador Sea

Abstract : The long term goal of this research is to understand the relation between atmospheric forcing and ocean deep convection. Objectives: 1. The primary objective is to use ocean numerical models, remotely-sensed information and in situ ocean data, to examine the sensitivity of the ocean to various atmospheric forcing specifications, the latter based on Objective 2-4 results. Try to understand the physics involved in the relationship between the atmosphere and deep convection. 2. Quantify the atmospheric forcing (heat flux, salt flux, momentum flux) for the entire Labrador Sea during the period of the 1997 R/V Knorr cruise using a combination of in situ, model, aircraft and remotely-sensed data. 3. Evaluate the accuracy of research (COAMPS) as well as operational numerical forecast models (NOGAPS, NWS products, ECMRF) in providing atmospheric forcing fields in the Labrador Sea during winter.
