In modern conditions of climate change and increasing pressure on water resources, river forecasting is becoming one the urgent tasks rational use. The main tool for long-term characteristics prediction are Atmospheric Oceanic General Circulation Models (AOGCM). this paper, we assessed quality a number climatic by CMIP-6 (Coupled Model Intercomparison Project, Phase 6) AOGCMs Volga Kama basins ...

Complex network theory provides a powerful framework to statistically investigate the topology of local and non-local statistical interrelationships, i.e. teleconnections, in the climate system. Climate networks constructed from the same global climatological data set using the linear Pearson correlation coefficient or the nonlinear mutual information as a measure of dynamical similarity betwee...

We quantify the long-term predictability of global mean daily temperature data by means of the Rényi entropy of second order K2. We are interested in the yearly amplitude fluctuations of the temperature. Hence, the data are low-pass filtered. The obtained oscillatory signal has a more or less constant frequency, depending on the geographical coordinates, but its amplitude fluctuates irregularly...
