ABSTRACT. Climate characteristics along the Bulgarian Black Sea coast from 1970 to 2009. For the regime of meteorological elements in Bulgaria influence have air masses coming from Atlantic Ocean, Mediterranean and Black Sea, and from mainland Europe. Weather and climate along the coast are different than in inland of country, and often periods with extreme events are observed. The aim of this work is to investigate and analyze monthly and annual variations and tendencies of the main meteorological elements (temperature and precipitation) along the Bulgarian coastline, with direct impact on the peoples lives. Data for mean, maximum and minimum air temperature and daily precipitation were used for 40 years period (1970-2009) from seven coastal meteorological stations. Statistics methods are used to calculate trend and determine his significance. Some periods differ from one another: i) 1971-1990 like relatively dry and cool, ii) 1991-1997 as relatively cool and moist, iii) 1997-2009 like warm and relatively dry.
