The paper presents the regionalisation of climate in Poland put forward by R. Gumiński in 1948. Although the author calls it an agrarian-climatic regionalisation (due to the choice of elements and characteristics of climate which served as a starting point), it can be considered as a general climatic regionalisation. The results obtained by Gumiński have been compared with results obtained by other authors, with special consideration of the applied methodology. Also conditions which regionalisation of climate should fulfil have been specified. The criteria for regionalisation adopted by Gumiński are undoubtedly subjective. In effect, the end result of such proceeding depends on an author's knowledge of and view on climate. The comparison of Gumiński's regionalisation of climates with climatic division obtained by multivariate statistical analysis shows large similarity of the results (Fig. 1 and 2). This follows Gumiński's understanding that - climatic division can only be approximate, - macro- and microclimatic changeability has to be distinguished, - the role of morfology of the relief in delineating climate boundaries cannot be overestimated. The above mentioned conditions have not been sufficiently considered in regionalisations of climate by other authors, who often adopted the concept of region, popular in geography, as a homogeneous unit separated from other units by more or less distinct boundaries. This last condition is difficult to fulfill due to both the nature of the factors shaping climate and considerable influence of factors operating in larger areas.
