This bachelor's thesis focuses on analyzing the influence of two meteorological factors—solar radiation and atmospheric circulation—on the occurrence of air temperature anomalies in Warsaw. The study utilizes measurement data from Warsaw between 2008 and 2023, collected at the observation station located on the rooftop of the Faculty of Physics at the University of Warsaw. The dataset includes daily values of air temperature and shortwave solar radiation intensity, as well as air mass back-trajectory modeling using the HYSPLIT model. Based on the obtained results, it was found that the occurrence of air temperature anomalies in Warsaw is strongly related to seasonal variations in solar radiation intensity and to the types of atmospheric circulation. The annual analysis of temperature anomalies revealed a recurring, increasing trend in the frequency of warm anomalies. A significant link between positive anomalies in solar radiation and temperature was observed, especially in the summer season. Furthermore, it was determined that air advection from the southwest promoted the occurrence of warm anomalies, while advection from the north contributed to their suppression. The seasonal analysis showed differences in the magnitude and frequency of temperature anomalies, with negative anomalies dominating in winter and positive anomalies prevailing in summer. A seasonal shift in the impact of eastern advection was also identified—favoring warm anomalies in summer and cold anomalies in winter. The conclusions drawn from this study may serve as a valuable contribution to further research on climate variability and as a basis for predicting local temperature anomalies.
