Abstract
The influence of the atmospheric circulation over Europe, the east Atlantic and north Africa on the sea surface of the Mediterranean and the Black Seas is studied for the 50-year period 1958–2007, during summer. The dataset consists of monthly (May-September) anomalies of: (i) sea surface temperature, sensible and latent heat flux, short and long wave radiation and total cloud cover for the sea surface and (ii) 500 and 1000 hPa geopotential height for the atmosphere. At first, Factor Analysis is applied in the data matrix of each field, in order to reduce its dimensionality. Then, the reduced matrices for the sea surface as well as for the atmosphere are unified in two final ones. Canonical Correlation Analysis is applied on these two matrices leading to five statistically significant canonical pairs. The correlation coefficients between the canonical variates and the original data indicate the centers of action for the connection between air and sea surface. The position and the intensity of a low/high pressure system and the corresponding trough/ridge over Europe, along with the physical geography of the Mediterranean and the Black Seas, regulate the anomalies of the sea-surface parameters.
