British researchers point to a period of warmer surface waters of the North Atlantic. You did not know who to blame for the rainy weather that hit this summer in the north and center of Europe? British researchers at the University of Reading held perhaps the culprit. According to their findings, which were recently published in the scientific journal Nature Geoscience, the temperature fluctuations of the North Atlantic Ocean are at least partly involved. Now, they are experiencing cycles, with a period of warming of surface waters and a cooling period, over a period of approximately 50 to 80 years. This phenomenon is called Atlantic Multidecadal Oscillation (AMO AMO or English). Thus, between 1931 and 1960, the North Atlantic Ocean has been a warm period followed by a cold period until 1990, when the trend is reversed again. According to Rowan Sutton and Buwen Dong, periods of warming, such as the one in which we currently find ourselves, are particularly suitable for rainy summers in the north and center of Europe, and on the contrary, a summer drought in the south of the continent. Similarly, it would promote spring and autumn fairly mild and dry in the north, but very watered south. All because of a complex set of interactions between ocean and atmosphere in which the OAM play a little role of a conductor, which would result in a change in the circulation and positioning of the jet-stream, a powerful current of air that moves between 6 and 15 kilometers above our heads. And there, bad news! Surface waters of the North Atlantic do not show, for the moment, leaving no sign of cooling influence more lenient hope for northerners in 2013.
