Typologisation of Synoptic Objects of the Area in Terms of Applied Statistics

Abstract

The purpose is to develop a methodology for revealing the internal structure of the mesoscale atmospheric circulation on the basis of the typologisation of synoptic situations of a certain season in a target area. Materials and methods. The initial information are the data of the NCEP/DOE AMIP-II reanalysis of atmospheric parameters. The methods of applied statistics are used: factor, cluster and discriminant analyses. Results and discussion. The factor model of the climatic population of synoptic objects is constructed taking into account their vertical structure; statistically diff erent groups of circulation objects are identifi ed (on the example of the winter season of the Voronezh point area). Conclusions. The methodology of typologisation of mesoscale synoptic situations for a certain season and a target area has been developed.
