Nowcasting Foehn Wind Events Using the AdaBoost Machine Learning Algorithm
Weather and Forecasting, 2017 Abstract 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. Traditionally, a foehn is predicted based on pressure differences and tendencies across the Alpine ridge. Here, a new objective method for

The impact of a foehn wind on PM10 concentrations and the urban boundary layer in complex terrain: a case study from Kraków, Poland [PDF]
Tellus: Series B, Chemical and Physical Meteorology, 2021 Kraków, Poland, is a city with poor air quality, located in the large Wisła (Vistula) valley, and affected by a foehn wind from the Tatra Mountains. We analyzed 14 long episodes of the foehn from the periods Sep 2017 - Apr 2018 and Sep 2018 - Apr 2019 ...

The surface energy balance during foehn events at Joyce Glacier, McMurdo Dry Valleys, Antarctica [PDF]
The Cryosphere, 2022 The McMurdo Dry Valleys (MDV) are a polar desert, where glacial melt is the main source of water to streams and the ecosystem. Summer air temperatures are typically close to zero, and therefore foehn events can have a large impact on the meltwater ...

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica. [PDF]
J PhycolAbstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Classification of Alpine south foehn based on 5 years of kilometre-scale analysis data [PDF]
Weather and Climate Dynamics, 2022 It has long been recognized that a rich variety of Alpine south-foehn flavours exist that are related to varying flow conditions above crest level, the presence and intensity of orographic precipitation on the Alpine south side, and the Po Valley ...
