In this article, we analyse the ability of climate models to produce south foehn in the valleys of western Austria using a machine learning technique and assess, how well they capture different aspects of annual foehn occurrence. The performance of these models is largely influenced by the underlying global climate model. After weighting the models based on their performance, we found that foehn occurrence slightly decreases with global warming, but events tend to become more widespread.

On 17 August 2024, a thunderstorm in Vienna led to a record-breaking rainfall of 107 mm in two hours. An analysis of the exceptionally long hourly rain gauge time series (since 1941) estimates this event's return period at 700 years. The extremity of the event is further confirmed by neighboring weather stations and rain-radar data. Linking the return period to atmospheric temperature shows that such events might occur more often with rising temperatures.

Climate model output has systematic errors which can be reduced with statistical methods. We review existing bias-adjustment methods for climate data and discuss their skills and issues. We define three demands for the method and then evaluate them using real and artificially created daily temperature and precipitation data for Austria to show how biases can also be introduced with bias-adjustment methods themselves.

Short summary
Snow occurrence, snow amount, snow density and liquid water content (LWC) can vary considerably with climatic conditions and elevation. We show that low-cost Global Navigation Satellite System (GNSS) sensors as GPS can be used for reliably measuring the amount of water stored in the snowpack or snow water equivalent (SWE), snow depth and the LWC under a broad range of climatic conditions met at different elevations in the Swiss Alps.

Short summary
Climate model output usually has systematic errors which can be reduced with statistical methods. We review existing bias adjustment methods for climate data and discuss their shortcomings. We define three demands for the method and combine two existing methods for our own approach. We then test it in comparison to two other methods using real and artificially created daily temperature and precipitation data for Austria. The results show that our method is able to meet all three demands.

Short summary
A continuously operating superconducting gravimeter at the Zugspitze summit is introduced to support hydrological studies of the Partnach spring catchment known as the Zugspitze research catchment. The observed gravity residuals reflect total water storage variations at the observation site. Hydro-gravimetric analysis show a high correlation between gravity and the snow water equivalent, with a gravimetric footprint of up to 4 km radius enabling integral insights into this high alpine catchment.

Short summary
Snow and rainfall measurements in mountain regions often underestimate the true amounts. We developed a method to correct Austrian precipitation data using weather stations and terrain features. The corrected data greatly improves runoff, snow and glacier modeling. This work shows that considering measurement errors is important for accurately assessing water resources, which is increasingly relevant as climate change affects alpine water systems supplying hydropower and downstream communities.
Snow and rainfall measurements in mountain regions often underestimate the true amounts. We...
