Atmosphere-ocean interaction on weekly timescales
Large-scale atmosphere–ocean interaction over the North Atlantic and North Pacific during winter using a 14-yr record of weekly sea surface temperature and atmospheric circulation fields is examined. Singular Value Decomposition is used to quantify objectively the degree of coupling between the sea...
