In this paper the nature, state and variability of the climate system are described briefly. Of particular importance in open systems such as components of the climatic system is feedback. Mathematical models provide a new way to not only understand

General Circulation Models (GCMs) are now the tools most widely applied in the generation of scenarios for climatic change on the global scale. One of the methods by which to move down from the global to regional scales is application of the LARS-WG
weather model, a stochastic weather generator simulating daily values for elements of the climate. An attempt to verify the model was made on the basis of data for the Zamość weather station. Discussion of the results.

The first part of this paper presents a review of methods used in the formulation of regional climate scenarios, while the next two parts contain an example of a regional climate scenario for Poland based on the output of the ECHAM1/LSG model

The issue of the influence of climatic change on water management is a source of controversy. Changes in Poland's water resources calculated with the aid of the CLIRUN-3 model differ in relation to the given climate scenario in terms of both
