Sommario/riassunto

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 173.The ocean's meridional overturning circulation (MOC) is a key factor in climate change. The Atlantic MOC, in particular, is believed to play an active role in the regional and global climate variability. It is associated with the recent debate on rapid climate change, the Atlantic Multi-Decadal Oscillation (AMO), global warming, and Atlantic hurricanes.  This is the first book to deal with all aspects of the ocean's large-scale meridional overturning circulation, and is a coh
