The results of studying the stability of sample estimates of statistical parameters for different segments of the initial time series of Neman River annual runoff values at Grodno Town in 1808–2000 are presented. Segments of the series with different extent of anthropogenic impact on runoff and types of atmospheric circulation are considered. Statistically significant changes were found to exist in the dynamics of Neman River annual runoff due to both natural-climatic and anthropogenic variations in the hydrological cycle.  相似文献

Variation of the number of days with thunderstorms on the territory of Belarus and peculiarities of their formation are considered. This number is of great spatial and temporal variability. The spatial variability of this thunderstorm characteristic in Belarus was estimated with the use of mapping. The temporal series of the number of days with thunderstorms were studied with the aid of standard statistical methods.  相似文献
