Summary
Recent variations in atmospheric circulation in the eastern Mediterranean are analyzed and discussed. Interdecadal differences in mean monthly 700 hPa geopotential heights for June, July, and August in the period 1951–1980 show a trend of decreasing pressure of the subtropical high pressure belt over the Sahara Desert. The decrease is observed in the magnitude of the high pressure, in its areal extent, and in its northward position. Broader variations in other meteorological variables, such as rainfall regimes, temperature fields, wind variability, and evapotranspiration rates, are discussed in relation to variations in pressure fields and in indices of circulation such as the North Atlantic Oscillation. The trend from the 1950s through the 1970s was towards more temperate summer climate in the region.
