| 英文摘要: | Measurements from the Soil Moisture Ocean Salinity (SMOS) satellite acquired during 2012 in the western North Atlantic are used to reveal the evolution of the sea surface salinity (SSS) structure of the meandering Gulf Stream with an unprecedented space and time resolution. Combined with in situ surface and profile measurements, satellite-derived surface currents, sea surface height (SSH), surface temperature (SST), and chlorophyll (Chl) data, SMOS SSS observations are shown to coherently delineate meanders pinching off from the current to form well-identified salty- (warm-) and fresh- (cold-) core Gulf Stream rings. A covariance analysis at two locations along the separated Gulf stream path (south of Nova Scotia and in the Gulf Stream Extension) reveals a systematically higher correlation between SSS and sea level variability than between SST and SSH during the warmer half of the year. Within (75°W-40°W; 30°N-50°N), Chl concentration is also found to significantly depend on the SSS as SST increases above 20°C. Key Points SMOS reveals SSS structure of the Gulf Stream with an unprecedented resolution Cold rings are better captured by SSS observations than by SST during summer Chl concentration in the separated Gulf stream significantly depend on SSS © 2014.
