ASSESSMENT OF CHANGES IN METEOROLOGICAL PARAMETERS AT THE RIVNE WEATHER STATION

The goal is to characterize the meteorological parameters at the Rivne weather station and evaluate their changes for the period from 2005 to 2020. The research methodology is built in the following directions: regression of observation data on time; the presence of connections between adjacent members of the series; construction of integral cumulative curves of meteorological parameters; graphs of surfaces are constructed, which make it possible to visually assess their forecast in the future; the homogeneity of the series of observations according to statistical parametric and non-parametric criteria is determined; calculation of the precipitation unevenness coefficient. The results of the comparison of integral curves show that long-term fluctuations of annual meteorological parameters are in phase, that is, for different meteorological parameters, the same phases can be observed at the weather station at the same time, but the ratio of average values for these phases changes. The sequence of phases of decrease and increase of certain meteorological parameters allows to distinguish cycles of their changes. The assessment of homogeneity according to parametric and non-parametric statistical criteria showed that there are changes in meteorological parameters: air humidity, wind speed, minimum air temperature, precipitation, which is statistically proven. The coefficient of uneven precipitation varies widely. The scientific novelty consists in the assessment of meteorological parameters at the Rivne weather station, which is proven statistically and its results can be used for other scientific assessments and research. The practical significance of the research results, namely the fact of changes in meteorological parameters, can be used in hydrological and geomorphological studies of the territory of the Volyn Polissia and the Volyn Highlands
