“…This result confirms findings from other parts of the world, indicating that atmospheric warming is occurring globally [14][15][16][17][18][19][20][21][22][23][67][68][69]. However, the average amount of precipitation remains the same (insignificant linear trend, Figure 1g), which is consistent with findings from other studies conducted in the Czech Republic [32], Serbia [69], and Slovakia [70]. In Slovakia, only 25% of weather stations recorded a significant increasing trend in precipitation, while no trends were observed in the remaining stations.…”

We evaluated the impact of weather and fertilization treatments (Control, PK, NPK1, NPK2, and NPK3) on winter wheat grain yields in a long-term trial in Ivanovice, Czech Republic, established in 1956. A total of 15 seasons were evaluated. The mean, maximal, and minimal temperatures in Ivanovice have been significantly increasing since 1961, with annual increases of 0.04 °C, 0.03 °C, and 0.05 °C, respectively. Precipitation has been decreasing annually by −0.54 mm (trend is insignificant). Four significant correlations between weather and grain yield were recorded. There were positive correlations between mean (r = 0.7) and minimal (r = 0.5) temperatures in November and negative correlations between mean temperatures in May (r = −0.6) and June (r = −0.6). The combination of naturally fertile chernozem soil and a beneficial preceding crop (alfalfa) enables sustainable cultivation of wheat, even without mineral fertilizers. The application of mineral nitrogen (N) significantly increases wheat grain yield and yield stability. Without mineral N or with high doses of mineral N, yield stability decreases. According to two response models (quadratic and quadratic-plateau), a reasonable dose of fertilizer is 107 kg ha−1 N for modern wheat varieties, corresponding to a yield of 8.1 t ha−1.

“…The status is chosen based on the previously specified intervals to represent the hydrological situation using the water-bearing approach. In both Gidra and Topľa Rivers, the last ten years were generally dry which confirms the findings of multiple studies (Almikaeel et al, 2022;Repel et al, 2021). Seven years over the period 2010-2020 are classified as dry years according to the water-bearing coefficient method.…”

Most Slovak rivers have increasing spring flow followed by a period or two of low flow in the summer, autumn, and, in some cases, winter. The flow rate fluctuations in two different streams in Slovakia are being investigated in this study. The study focused on an under-mountain and a lowland-highland river to investigate the low and peak flow periods and to identify the trends in monthly and annual mean flows for both rivers. Analysing daily mean discharge data from two different types of streams requires the use of a robust normalization approach to verify the comparability between the chosen streams. On both streams, a broad statistical low-flow analysis was performed over different study periods, as well as a hydrological drought analysis utilizing the water-bearing coefficient approach over the period 2010-2020. The evaluation for the foothill river in Slovakia demonstrates that snow melting has a significant impact on annual runoff in the spring months, and both rivers have a low flow period in August, September, and October. Despite the considerable variations in the catchment area, geographical, and hydrological characteristics, drought analysis for the years 2010 to 2020 found a lack of normality and a dry hydrological situation in both streams.

“…The same results were shown in the study (Dong and Menzel, 2019) carried out for the central European region covered by low mountains. The precipitation, in particular, in the cold period, generally did not change essentially (Repel et al, 2021;Rožnovský et al, 2020;Kubiak-Wojcicka, 2020). Many studies show the decrease tendency of wind speed (Birsan et al, 2020;Marin et al, 2014;Spinoni et al, 2015;Vyshnevskyi and Donich, 2021).…”

Based on the results of regular monitoring during 1961-2020, the main features of snow cover in the Ukrainian Carpathians were determined. The observation data at the meteorological stations, mainly located at high altitude, show an increasing trend in snow cover depth in winter and in the first half of spring. At the same time, there is a decrease in snow cover duration at low altitudes and an increase at high altitudes. General trends for the mountain area are higher air temperature and lower wind speed. Simultaneously precipitation changes are small or absent. It has been shown that decrease of wind speed over the last decades should be taken into account to determine the actual changes in snow cover. As a result of this decrease, the snow cover depth in the mountains became more uniform than at the beginning of the observations: larger on mountain tops and smaller in ravines and mountain forests. This means that in general, the snow cover depth and snow water equivalent in the mountains are stable. This was confirmed by the fact that during spring flood the water runoff of local rivers remained without essential changes.
