Combined Effects of the North Atlantic Oscillation and the Arctic Oscillation on Sea Surface Temperature in the Alborán Sea

摘要: We explored the possible effects of North Atlantic Oscillation (NAO) and Arctic (AO) on interannual sea surface temperature (SST) variations in Alboran Sea, both separately combined. The probability observing mean annual SST values higher than average was related to NAO AO previous year. effect negative, while that positive. pure are obscuring each other, due positive correlation between them. When decomposing SST, seasonal values, we found variation winter significantly autumn year, summer one year delay could be partially amount accumulated snow, as a significant total snow watershed for with subsequent A implies colder atmosphere Polar Regions, which favour occasional cold waves over Iberian Peninsula which, when coupled precipitations favoured by negative NAO, may result precipitation. This high peaks melt down spring-summer following consequently increases runoff freshwater sea, turn causes diminution salinity density, blocks local upwelling water, resulting SST.
