Many theories of climatic classification and of division of climatic regions of the world have been presented in general books on climatology and on physical geography. However, few reports trace the current of thoughts synthetically from the very root of studies up to the present. In the present paper the author has an object to follow the development of thoughts successively and point out how the thoughts of significance had been exploited and developed further. This paper consists of three parts ; namely, an examination of effective methods, a discussion of the problem of humid and arid boundary, and an examination of genetic methods. Effective methods since the 1840's are examined. Some earlier works by Hult, Supan, Köppen, de Martonne, Philipsson etc. were followed by several modern works by Blair, Trewartha, Creutzburg Troll, etc. Special attention is paid to make clear the current of thoughts, regarding representative standards for clamatic classification and for objective divisions into climatic regions. Then, the problem of the boundary between humid and arid regions are reviewed and examined. The concept of effective humidity originated in Linssers's earlier work has been developed by various successors, in order to make clear the water budget or the limit of arid region, indirectly. Physiogeographic consideration by A. Penck was a pioneer work of importance. After genealogic consideration of various methods for evaluating aridity of climate (indices such as Regenfaktor, indice d'aridité, quotient pluviothermique, precipitation effectiveness etc.) and their applicability to distinguish humid and arid climates, the author examines concisely the approach to the rational classification of climate introduced by Thornthwaite, and developed by his successors. It is also pointed out that there are two currents of thoughts regarding the main division of climatic regions of the world. One is to divide, except for the polar region, the world into humid and arid regions, then to subdivide the former into thermal zones and the latter into regions depending upon the degree of aridity. The other is, on the contrary, to divide the world into several thermal zones, and then to subdivide them into subregions, based upon the degree of aridity or humidity of climate. The standpoint of these approachs, therefore, are different to each other. Finally, genetic methods of classification of climate and their applicability to the presentation of climatic regions are examined. The root of such a current could be found in the early works on wind systems or windregions of the world introduced by Mühry, Wojeikof, Köppen, Hettner etc. during the latter half of the last century and the first half of this
