The vertical aerosol stratification within and above the Rhine Valley was studied with a backscatter lidar during FORM (Foehn in the Rhine Valley during MAP) IOPs 4-5, October 1-3, 1999. The lidar site was in Tr¨ubbach, 9° 28 E, 47° 04 N, 490 m asl.

Evaluation of Ensemble‐Based Extreme Forecast Diagnostics for Zonda Wind Prediction
Abstract Zonda is a downslope windstorm on the eastern slopes of the Andes in western Argentina. This Foehn‐like phenomenon can produce hazardous, strong, and gusty downslope winds, leading to extreme and rapid warming with severe societal impacts. Despite substantial advances in numerical weather prediction, forecasting Zonda winds remains challenging.

Numerous studies have elucidated that white heads and chalky rice are caused by hot, dry and strong winds at night. However, these studies have only used synoptic weather charts and near‐surface observation data to confirm the role of foehn in white head

Modelling Storage‐Discharge Relationships in an Alpine Basin in the Canadian Rockies
CRHM was used to model storage‐discharge relationships for Fortress Mountain Research Basin, an alpine basin in the Canadian Rockies. The model showed reasonable predictions of snow accumulation, snowmelt, liquid soil moisture, and streamflow, and nonlinear and hysteretic storage‐discharge relationships for this alpine basin.

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading
Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was

Nowcasting Foehn Wind Events Using the AdaBoost Machine Learning Algorithm
The south foehn is a characteristic downslope windstorm in the valleys of the northern Alps in Europe that demands reliable forecasts because of its substantial economic and societal impacts.

The "Mini-foehn" of Mittenwald- A comparison of measurements and modelling
Strong nocturnal downvalley winds can often be observed in the Isar Valley near Mittenwald (Bavarian Alps) under the influence of high pressure systems over Central Europe or in the presence of ambient southerly winds.

A Lagrangian framework for detecting and characterizing the descent of foehn from Alpine to local scales [PDF]
When foehn winds surmount the Alps from the south, they often abruptly and vigorously descend into the leeside valleys on the Alpine north side. Scientists have long been intrigued by the underlying cause of this pronounced descent.

Cold waves in northern Europe and the Alps have severe impacts on daily life sectors. Our study shows that they have become less frequent, shorter, and milder over the past eight decades despite ongoing regional variability. In addition, cold waves are sensitive to the large‐scale circulation.
