У роботі визначені просторові та часові закономірності руху льодового покрову півострова Київ в період з 2015 по 2025 рік, виявлені в результаті аналізу поля швидкостей руху льодовика Труз, отриманого з використанням радіолокаційних зображень Sentinel-1. Встановлено роль кліматичних чинників у формуванні процесів переміщення льодовикового покрову, перевірено наявність циклічних компонентів в динаміці його руху та загальних трендів до прискорення (сповільнення) швидкості переміщень льодовика.
Problem Statement and Purpose. The study of glacier cover dynamics is one of the key areas of modern climatology and glaciology, and in the context of ongoing global warming, the investigation of glacier behavior patterns is of particular relevance. The aim of this work is to identify the spatial and temporal regularities of ice cover movement on the Kyiv Peninsula during the period 2015–2025 and to determine the role of climatic factors in shaping these processes. Data and Methods. The research was carried out using Sentinel-1 radar imagery (to obtain the velocity field of the Trooz Glacier) and climatic parameters derived from satellite observation systems of the NASA POWER project. A set of mathematical and statistical methods was applied for data processing and analysis, including cluster analysis, correlation analysis, and spectral analysis. Results. The research revealed the spatiotemporal patterns of ice cover dynamics on the Kyiv Peninsula in 2015–2025. During the observation period, the velocity of control points on the surface of the Trooz Glacier varied within a wide range from 0.03 to 4.4 m/day. The obtained results indicate a complex character of ice cover dynamics. It was established that the Trooz Glacier is characterized by internal spatial heterogeneity of displacement dynamics, with its entire area being divided into 53 segments based on the similarity of movements. The analysis also demonstrated the general possibility of climatic parameters influencing glacier velocities, with temperature being identified as the most significant driver of glacier dynamics. Furthermore, for certain glacier segments, including its terminus area and parts of the main valley, a pronounced annual cyclicity was observed, with a clear acceleration of glacier movement in summer (December–February), corresponding to elevated temperatures that trigger ice melt. At the same time, no consistent trend of long-term acceleration of glacier velocity was identified.
