This study examines the spatial and temporal characteristics of surface air temperature (SAT) changes in Ukraine from 1990 to 2021. It focuses on the seasonal and regional variabilities, long-term trends, the harmonic characteristics of the annual temperature cycle, and their implications for regional climate change. From meteorological observations at 93 weather stations (Ω93 dataset), the average annual SAT was 9.6±0.8 °C. Over the past three decades, the mean rate of temperature increase reac
