Abstract

TRANSPORT VARIABILITY OF LABRADOR SEA WATER THROUGH FLEMISH PASS IN RELATION TO CHANGES AT 53°N

The Labrador Sea (LS) is characterized by a cyclonic boundary current surrounding one of the most active areas of water mass transformation in the Atlantic. Labrador Sea Water (LSW), formed in the LS from deep convection events, is exported to the subtropical gyre at the western boundary, namely through Flemish Pass (FP) or by the Deep Western Boundary Current (DWBC) around Flemish Cap (FC). The focus of this study is to investigate the variability of the upper and deep LSW transports with respect to the seasonal and interannual variability through FP (at 47oN) and around FC (at 47oN in the DWBC) and to relate the variability 1) to upstream fluctuations at 53°N and 2) to atmospheric forcing conditions. Data derived from the ocean model MITgcm with a horizontal resolution of 1/12° (~7.5km) over the period 1958-2009 is analyzed, as well as the variable atmospheric forcing from the NCEP/NCAR reanalysis. The seasonal and interannual time scale variability at FP are negatively correlated with the variability at 53oN and 47oN in the DWBC due to the anticyclonic flow above FC.
