Climatic change of the Baltic Sea level and sea surface temperature based on satellite altimetry and radiometry

摘要

As it was shown recently, climate changes in the Baltic Sea resulted in interannual trends of some climatic parameters like sea level atmospheric pressure, surface air temperature, ice thickness and others. These tendencies have effect on the Baltic Sea meteorological and hydrological regime. The following remote sensing data: GODAE (Global Ocean Data Assimilation Project) High Resolution Sea Surface Temperature data and satellite altimetry data of mission TOPEX/Poseidon and Jason-1/2 are used to analyze the interannual and/or climatic tendency of sea surface temperature (SST) and sea level anomaly (SLA). According to the obtained results, on average for the entire the sea area in the period 1992–2013 SST has positive trend +0.06±0.03 °C/yr and SLA also has positive interannual trend +0.33±0.07 cm/yr. For different time intervals SST and SLA are decreased or dropped.
