Abstract

Based on the analysis of daily air temperature anomalies in Kiev during the last century, it is found that the extreme positive anomaly naturally can reach +15.13 ºC, exceeding the observed maximum by 1º. The climate process was stable and not subjected to human-induced deformations. We propose a stochastic model of the dynamics of air temperature anomalies, which is built on the "Wiener walks" held under natural climatic boundaries of the Ornstein–Uhlenbeck process.
