The paper analyzes the integrated water vapor content (IVG) variability in the southern Baltic Sea during the period 1988-2005 using Special Sensor Microwave (SSM/I) data. IVG means were obtained from satellite-based database applications (CM SAF) archives. It was found that the mean of IVG was 13.58 kg/m2 in analyzed area. IVG fluctuations are seasonal. The driest climate in the southern Baltic Sea is in period of December-March (cold period) and the wettest -- June-September (warm period). IVG reached mean maximum in July (21.45 kg/m2) and minimum -- in March (8.59 kg/m2). 1993 and 1996 were anomaly years. In those years IVG means were lower than the observed long-term mean. In 1993 IVG mean was 12.8 kg/m2 and in 1996 - 12.9 kg/m2. The analysis showed that IVG means values were higher than the long-term mean in 1999 (0.72 kg/m2). IVG means were higher than the multiannual average values (respectively 0.67, 0.58 and 0.59 kg/m2) in 1999--2000 and 2002. The main reasons leading to IVG anomalies are SST variations over the period, excluding the year 1999. The eastern Baltic Sea surface temperature positive deviations of October-December months affected positive anomalies of IVG. Sea surface temperature fluctuations of July-September months affected IVG negative variations, excluding the year 1999. In April 1999 the positive temperatures anomalies were higher more than +4.0 °C in the Baltic states (Annual Bulletin…, 2000). It was found that the highest IVG values in warm period (July-September) were in regions closer to the coast (55°-57° N and 19°- 21° E), and in the period of January-March the lowest IVG means were in 56°-57° N and 17°-21° E area.
