In researches over level of endowment to technical infrastructure, but especially in spatial comparative analyses it is helpful application of multidimensional statistics methods, allowing on assignment of synthetic measureMeasures substitute numerous set of the feature of researched object (variable characterizing individual elements of technical infrastructure) with one aggregate variable.Such approach enables estimate of object (communes) by one largeness and it allows ordering of analyzed object based on treated problem (level of infrastructural development). The purpose of article is assignment of development measure of technical infrastructure according to various methods of constructing of synthetic measures, and comparison received results. The objective is verification how the application of different aggregation methods of the same diagnostic variable effects results, manner and which from suggested methods seem adequate for researches over technical infrastructure.Were chosen 5 different proposals of constructions of synthetic variable and were compare received results according to them these methods.Object of research presents 20 mountain communes in the podkarpackie province. For construction of synthetic measure were accept 8 diagnostic variable characterizing elements of technical infrastructure of country area. ...
This article presents the analysis of atmospheric circulation conditions per-taining to agricultural droughts in the Podkarpackie Province during the growing season (1901-2000). The following resource materials have been used: daily ca-lendar of atmospheric circulation types elaborated by T. Niedzwiedz for southern Poland, and growing season meteorological calendar elaborated by T. Zawora for southern Poland for the following monthly periods. The author had to determine the frequency of atmospheric circulation types for months which have been recognized by agricultural specialists as too dry (due to precipitation deficit). Drought hazard may be expressed by the following ratio: frequency of occurrence of a given circulation type during drought conditions to general frequency of circulation types. This method enabled to present detailed results. Firstly during the growing season the anticyclonic circulation type - advection of air from southwest - occurs 1,38 more frequently than the general frequency of this particular circulation type (SEa). The situation is similar for types Sa and Ea (1,35 and 1,33 respectively). When we examine the remaining values we can notice that the fre-quency coefficient for anticyclonic ridge (Ka) is equal to 1,21, whilst for anticyclonic situation with advection of air from northeast (NEa), and for central anticyclonic situation (Ca) ...
