A radar-based regional extreme rainfall analysis to derive the thresholds for a novel automatic alert system in Switzerland

Alexis Berne, Marco Gabella, Luca Panziera

This paper presents a regional extreme rainfall analysis based on 10 years of radar data for the 159 regions adopted for official natural hazard warnings in Switzerland. Moreover, a nowcasting tool aimed at issuing heavy precipitation regional alerts is in ...

Subfossil peatland trees as proxies for Holocene palaeohydrology and palaeoclimate

Luca Bragazza

Due to the scarcity of reliable and highly resolved moisture proxies covering much of the Holocene, there has been increased interest in the study of living and subfossil peatland trees sensitive to gradual and extreme changes in hydrology, precipitation, ...

Reconstructing climate change and ombrotrophic bog development during the last 4000 years in northern Poland using biotic proxies, stable isotopes and trait-based approach

Vincent Eric Jules Jassey

In this study, we present a record spanning the last 4000 years from a Baltic bog (Kusowskie Bagno) in northern Poland. Using numerous biotic and abiotic proxies, such as testate amoebae (depth to water table reconstructions), stable carbon isotopes (C-13) ...

Use of a multilayer snow model to assess grazing conditions for reindeer

Michael Lehning

High-density snow layers deteriorate grazing conditions for reindeer during winter. We compare two different methods for identifying past winters with difficult grazing conditions for reindeer in Kautokeino, northern Norway. A long-term climate analysis ba ...

A robust framework for probabilistic precipitations downscaling from an ensemble of climate predictions applied to Switzerland

André Mermoud, Bettina Schaefli, Xavier Beuchat

Rainfall is poorly modeled by general circulation models (GCMs) and requires appropriate downscaling for local-scale hydrological impact studies. Such downscaling methods should be robust and accurate (to handle, e.g., extreme events and uncertainties), bu ...

An analytical model for soil-atmosphere feedback

Bettina Schaefli

Soil-atmosphere feedback is a key for understanding the hydrological cycle and the direction of potential system changes. This paper presents an analytical framework to study the interplay between soil and atmospheric moisture, using as input only the boun ...
