Cyclones and anticyclones are the main objects in study o&f the atmosphere circulation in midlatitudes. Consideration of baric systems, which usually are very mobile objects with complex vertical structure, requires analysis of general features of their genesis and evolution on the one hand as well as well &as specific dynamic characteristics in each moment of their existence. Results of such analysis allow performing a classification of baric systems based on different features and systematize atmospheric processes in general. Currently such an approac&h in baric systems study applies exclusively to the cyclones, while anticyclones become an object of research mainly in the context of atmospheric blocking. In this situation a lack of unified methods, which can be applied to both cyclones and anticy&clones, became obvious.
The purpose of this research is to compose a set of parameters for integral specification and characterizing of extratropical cyclones and anticyclones movement in the low and middle troposphere and propose methods of their c&alculation. Region of baric system"s spatial spread describes its general spread in the troposphere. Localization of this region is based on recognition of zones, outlined by baric system"s enclosed isolines on each vertical level, where it is presen&t during its whole lifetime. Intensity of baric system is defined though its accumulated presence within the region of its spatial spread. The more baric system exists and the less it moves, the more intensive it is considered. Geopotential height an&omaly, calculated on the highest level of baric system"s vertical spread, allows to intercompare different baric systems regardless to their seasonal features. Mode of baric system movement takes into account its velocity to describe behavior on the &different parts of its trajectory. Calculation of this characteristic performs in different way for cyclones and anticyclones due to difference of their nature and defined with different categories. Baric system movement direction describes vector of& its overall displacement and depends on location of the first and the last points of trajectory. Digital encoding of calculated characteristics allows to intercompare baric systems easily taking into account up to six parameters at once.
Developed &methods of baric system"s characteristics estimation are universal and simple enough to study various types of atmospheric processes over extended periods of time easily.
