The response of the general circulation of the Baltic Sea to climate variability

摘要: The warming trend for the entire globe is 0.04°C per decade period 1850-2005. Furthermore, from around 1980 to present, a specifi c started, with temperature increase of about 0.17°C decade, especially on northern hemisphere. For Baltic Sea catchment, which located between maritime temperate and continental sub-Arctic climate zones, an even stronger 0.4°C was observed since 1980. Changes in atmospheric conditions cause corresponding changes Sea, not only salinity, but also currents circulation patterns. analysis winter (DJFM) patterns 1970-2008 reveals general of the Sea. While it diffi cult clearly link individual one four dominant regimes North Atlantic domain, comparison mean 20- year periods (1970-1988 1989-2008) highlights that later 20-year intensifi ed cyclonic exists central This results westerly north-westerly winds most likely connected large-scale circulation.
