In this study, the spatial and temporal distributions of dynamic andsynoptic characteristics of a selection of 32 deep baroclinic depressionshave been investigated. The study covers the cold period months of Novembertill March, in the period from 1 November 1986 to 31 March 2003. For the needs of the study, several synoptic characteristics ofthese depressions have been extracted. Also, several dynamic characteristicsduring the evolution of the depressions were studied: relative vorticity,divergence, vertical motion and a static stability parameter. The resultsare presented in the form of isobaric distributions over, three troposphericisobaric levels, namely the lower 850 hPa, the middle 500 hPa and the upper300 hPa.
