Nonstationarities in technical precipitation series in Czechia

Popis výsledku v původním jazyce

Under the proper consideration of climate change one cannot rely on the stationarity of the series fed to a hydrological model. Modelling should rather be based on the assumption of nonstationarity with appropriate discrimination between deterministic and stochastic trends in the series. Although some works regarding the identification of trends in precipitation across the entire territory of Czechia were undertaken, they primarily accounted for the deterministic and linear relationships only. What is more, the results in many former studies inevitably had to be biased due to missing values and inhomogeneities introduced during measurements. In the present paper, trends in 268 complete and homogeneous precipitation series from Czechia spanning from 1961 to 2012 are detected by means of several statistical techniques. Subsequently, places with different kinds of nonstationarities are determined.
