Precipitation conditions at the mountain study site of Bílý Kříž (the Beskids Mts.) during the past 20 years
Expected global climate change can cause changes in several hydrological cycle processes, such as the intensity and frequency of precipitation, river flows, evapotranspiration rates, soil moisture, and groundwater recharge. Precipitation conditions have been observed at the mountain study site of Bílý Kříž (the Beskids Mts., Czech Republic) since 1989. This paper presents the analysis of long-term (1997–2016) precipitation conditions at this study site. Comparison of selected long-term mean precipitation characteristics with mean precipitation characteristics for the 1997–2016 period reported differences in only some parameters. The number of days without precipitation was slightly increasing. No statistically significant trend was found for the number of days with heavy rain. The study site was changed from being a per-humid to humid type as indicated by Lang’rain factor. More dry periods were determined at the past decade according to the standardized precipitation index.
