Abstract
The seasonal and interannual variability ofcloud fraction over the Black Sea region for the period of1985-2009 is analyzed using the CM SAF dataset obtained from the satellite measurements of a high-resolution AVHRR instrument. The features of geographic distribution and seasonal variations in cloudiness are investigated. The causes for its spatial inhomogeneity in different months are analyzed. It is demonstrated using the long-term dataset that the dramatic decrease in the amount of cloudiness occurred over the Black Sea region from 67% in 1985 to 54% in 2008. The value of the trend is -0.4% per year. Both the trends and the features of interannual variability of cloudiness, in particular, strongly pronounced four-year cycles, are in antiphase with variations in sea surface temperature. The cloudiness reduction accompanied by the increase in the influx of short-wave radiation may be the basic reason for the warming and sea surface temperature variations in the Black Sea region.
