摘要：The reliability of parameters epends mainly on the representativness of data concerning the character of changeability of phenomenon. Those parameters characterize constant environmental phenomena and their reliability is obtained derivatively from the models of their values’ distribution. Constant phenomena qualified on the basis of insufficient number of indicating points are particular subject to diversified outcomes. The precipitation was an example on which different trials to obtain constant information on the basis of phenomenon’s model constructed from the point data were tested. Mainly the average values obtained during many years are used for modeling climatic conditions. Nowadays,to create model of climate elements all available data of different levels of reliability are used. Because of that fact,information obtained from the model is always going to include uncertainty either because of mistakes in data on which the analysis in based or imperfection of their transformation procedures. In the article the following ways to indicate values on the basis of point observations are proposed: the basis field as Voronoi’s mosaic,cluster analysis and approximation using spline functions.
