Clustering of small watersheds over annual precipitation data reveals sounding correspondence to the cluster pattern determined by annual temperature course

Abstract

Abstract Previously, highly informative clustering of small watersheds provided over the annual temperature course has been reported. Here we report on the interplay between the pattern and the distribution of small watersheds developed over the annual precipitation data. A sounding correlation between these two cluster structures is found. To reveal the correspondence, smart methods of both spatial and comprehensive analysis have been implemented. We used advanced GIS tools to detect the spatial behavior of the data under consideration, and elastic map technique to reveal the cluster patterns in the space of environmental data (temperature and precipitation). Some further applications and perspective studies in this area are discussed.
