Integruoto vandens garų kiekio virš Baltijos regiono klimatiniai rodikliai.

The paper deals with the integrated water vapor (IWV) climatological regime and dynamics over the Baltic Sea region. It is the authors' ongoing work on the distribution of atmospheric moisture over the Baltic region, based on climatic remote sensing database. IWV daily means were obtained from the Satellite Application Facility on Climate Monitoring (CM SAF) archives for period 2004-2011. It was found that IWV long-term mean over the Baltic region is 15.38 kg/m². IVG average gradient is oriented north-south direction. The average difference between northern and southern part of the area is 2.1 kg/m². IVG has a seasonal variation: IVG maximum amount of midsummer at least three times higher than the late winter minimum. The largest horizontal IVG gradients are over the sea-land boundary areas. In October-March period IVG mean is higher 3% over sea surface than over land. In April-September IVG mean is 5% less over sea surface than over land. Homogeneity analysis showed that the ATOVS and SSMI / IVG data series over the central part of the Baltic are homogeneous only in the cold season from November to April. These data sets combined into one long data set helped to determine the climatic IVG indicators over the Central Baltic in 1989-2010. [ABSTRACT FROM AUTHOR]
