The article presents the results of an analysis of the number, frequency and intensity of tropical nights in Ukraine. We have selected such weather stations that are located at different latitudes and correspond with the north, west, east, and south as well as the central part of Ukraine. This was done in order to analyse the differences in tropical nights across latitudes. Also we have weather stations located at the approximately one latitude to analyse how tropical nights vary in longitude. Data from weather stations for 1976-2019 were under analysis. We can say that the increase in the minimum air temperature during summer is on the whole territory of Ukraine. This leads to the fact that since the mid-1990s tropical nights begin to be observed in the east of Ukraine, as well as in the south. After 2000, tropical nights also have begun to be observed in the centre and even in the west of Ukraine. Between two half-periods (1976-1997 and 1998-2019) the increase of number of tropical night events in the south of Ukraine (up to 300 cases) is much more significant than the increase in their number in the northwest (up to 20 cases). As well as the frequency, the intensity of tropical nights also increases. There are cases with minimum daily air temperatures above 25°C. The analysis of the North Atlantic Oscillation (NAC) and the Mediterranean (Cairo-Algeria) indices in the context of explaining the tropical night’s occurrence in Ukraine turned out to be quite effective.

“…Numerous studies have consistently demonstrated that the frequency, duration, and spatial extent of warm/ hot extremes, including tropical nights, change in parallel with the increase in minimum temperatures regionally or globally (e.g., Abatan et al, 2019;Alexander et al, 2006;Donat & Alexander, 2012;Elizbarashvili et al, 2017). For example, Alexander et al (2006) determined significant positive trends in the annual number of tropical nights over central and southwest Asia, the northern part of Africa, andsouthern Brazil between 1951 and2003, suggesting a global upward shift in the distribution of daily minimum temperatures throughout the globe.…”

Elizbarashvili et al (2017) reported an increase in tropical nights in Georgia, particularly along the Black Sea coast and the Kolkheti lowland, by 4-6 days per decade from 1936 to 2013. Abatan et al (2019) highlighted significant upward trends in tropical nights across three Nigerian regions (Guinea 0.39, Savanna 0.52 and Sahel 0.60 days per decade annually) between 1971 and 2012.…”

The Mediterranean region, noted for its climatic uniqueness and rapid urban expansion, is a critical area for climate change studies. This research investigates the increase in extreme temperatures, particularly focusing on tropical nights and their socio‐economic implications. Our aim was to analyse the spatiotemporal changes, including long‐term variation and trends in the tropical night indices in the Mediterranean region over 73 years (1950–2022). To achieve this, we utilized ERA5‐Land reanalysis data, conducting a comparative analysis to highlight the differential impacts of urbanization on tropical nights in urban and non‐urban areas. The study reveals a significant rise in the frequency of tropical nights region‐wide. Specifically, the onset of the tropical night season is occurring earlier, with an advancement of approximately 17.3 days per decade, while the season's end is delayed by about 17.1 days per decade, effectively prolonging the duration of tropical nights. This change is most pronounced in urban areas, where tropical nights have increased more significantly compared to non‐urban regions, highlighting the exacerbating effect of urbanization on nocturnal temperature trends. Overall, our findings underline the combined effects of anthropogenic climate change and urban development on the increased occurrence and intensity of tropical nights in the Mediterranean region.
