Caption from Oceanus magazine, Vol. 39, No. 2., Pg. 21:
The history of temperature (circles and black line) of the Labrador Sea Water convecting in the central Labrador Basin to depths sometimes exceeding 2,000 meters. This is compared to the inter-decadal march of an index of the North Atlantic Oscillation, with the reds indicating the high index periods of strong westerlies, and the blues the low index periods of weak westerlies. See the North Atlantic Oscillation box on page 13 for an explanation of the high and low states of the “NAO”. The NAO index plotted here is formed from the sea-level pressure difference between the subtropical Azores high pressure center and the subarctic low pressure center near Iceland. The authors thank James Hurrell (National Center for Atmospheric Research) for the latest updates of NAO index data.
