Rain falling on snow accelerates snowmelt and can affect runoff and cause severe floods. We assessed potential regional and seasonal variations in RoS occurrence in mountainous catchments in Central Europe, using a sensitivity analysis through hydrological model. The results showed that climate change-driven RoS changes vary highly among regions, across elevations, and within the cold season. However, most projections suggested a decrease in the number of RoS and reduced RoS-driven runoff.

The study introduces a novel benchmarking method based on the water cycle budget for hydroclimate data fusion. Using this method and multiple state-of-the-art datasets to assess the spatiotemporal patterns of water cycle changes in Czechia, we found that differences in water availability distribution are dominated by evapotranspiration. Furthermore, while the most significant temporal changes in Czechia occur during spring, the median spatial patterns stem from summer changes in the water cycle.

The study deals with ultraviolet (UV) radiation in southern polar conditions, where ozone depletion occurs each spring. A 10-year-long time series of UV spectra from Marambio Base, Antarctic Peninsula, has been studied, with a focus on the changes of UV radiation at different wavelengths and the effects of atmospheric and terrestrial variables like ozone, solar elevation, or cloudiness. At the very short wavelengths, the effect of ozone and its deficiency was clearly observed.

Short summary
High-latitude dust (HLD) is a short-lived climate forcer, air pollutant, and nutrient source. Our results suggest a northern HLD belt at 50–58° N in Eurasia and 50–55° N in Canada and at >60° N in Eurasia and >58° N in Canada. Our addition to the previously identified global dust belt (GDB) provides crucially needed information on the extent of active HLD sources with both direct and indirect impacts on climate and environment in remote regions, which are often poorly understood and predicted.

Short summary
The direct observation of hydrologic processes within a large glacier is rather difficult, therefore we used publicly available remote sensing data in order to describe hydrologic processes of a marine terminating glacier and demonstrated that such tools and data can be easily used. Spatial and temporal pattern of melting dynamics during five consecutive years was described through mapping of supraglacial lakes and sediment plumes areal extent.

Short summary
Snow processes are crucial for runoff in mountainous areas, but their complexity makes water management difficult. Temperature models are widely used as they are simple and do not require much data, but not much thought is usually given to which model to use, which may lead to bad predictions. We studied the impact of many model alternatives and found that a more complex model does not necessarily perform better. Finding which processes are most important in each area is a much better strategy.

Changes in snow affect the runoff seasonality, including summer low flows. Here we analyse this effect in 59 mountain catchments in Czechia. We show that snow is more effective in generating runoff compared to rain. Snow-poor years generated lower groundwater recharge than snow-rich years, which resulted in higher deficit volumes in summer. The lower recharge and runoff in the case of a snowfall-to-rain transition due to air temperature increase might be critical for water supply in the future.

In order to broaden the knowledge of long-term UV radiation variability, we have reconstructed and analyzed a 50-year-long UV radiation time series from Hradec Králové, Czech Republic. The UV radiation intensities increased greatly following the decline of ozone amounts in the 1980s and 1990s. High UV radiation doses were observed in days with low ozone amounts, clear or partly cloudy skies, or snow cover.

We quantified how long snowmelt affects runoff, and we estimated the sensitivity of catchments to changes in snowpack. This is relevant as the increase of air temperature might cause decreased snow storage. We used time series from 14 catchments in Switzerland. On average, a decrease of maximum snow storage by 10 % caused a decrease of minimum discharge in July by 2 to 9 %. The results showed a higher sensitivity of summer low flow to snow in alpine catchments compared to pre-alpine catchments.

Short summary
The annual variability of runoff has not been analysed in the maritime Antarctic. Thus, we simulated and analysed rain, snow and glacier contributions to runoff related to climate variability in a small catchment over 11 years. The majority of the runoff came from snowmelt. Inter-annual variability in total runoff was associated with large variability in glacier runoff. Between October and May, 92 % of the runoff occurred, with significant runoff events outside the usual measurement season.
The annual variability of runoff has not been analysed in the maritime Antarctic. Thus, we...
