Abstract: ross-barrier density differences and westerly flow established a descending stratified flow across the Sierra Nevada (United States) on 9?10 April 2006. Downslope flow and an internal hydraulic jump occurred only when the ...

Abstract: combination of real and virtual topography is shown to be crucial to describe the essentials of stratified flow over mountain ranges and leeside valleys. On 14 March 2006 [Intensive Observation Period 4 of the Terrain-Induced ...

Abstract: The potential for a stably stratified air mass upstream of the Sierra Nevada (California) to descend as foehn into the nearly 3-km-deep Owens Valley was studied for the 2 March 2006 case with observations from sondes, ...

Abstract: Foehn winds often depend on topographical features of a scale that is not sufficiently resolved in numerical models. Consequently, a successful foehn forecast has crucially depended on the experience of bench forecasters. ...

Abstract: hree methods to make probabilistic weather forecasts by using analogs are presented and tested. The basic idea of these methods is that finding similar NWP model forecasts to the current one in an archive of past forecasts ...

Abstract: A case study of a south foehn windstorm observed across the Brenner Pass in the Wipp Valley near the Austrian?Italian border is presented based on a detailed comparison and verification of high-resolution numerical simulations ...

Abstract: An instrument package to measure temperature, pressure, humidity, and position was designed to be quickly deployable on any automobile to be used for the study of gap and other orographically influenced flows. Differential ...

Abstract: iagnosing foehn winds from weather station data downwind of topographic obstacles requires distinguishing them from other downslope winds, particularly nocturnal ones driven by radiative cooling. An automatic classification ...

Abstract: ind speed measurements from one year from meteorological towers and wind turbines at heights between 20 and 250 m for various European sites are analyzed and are compared with operational short-term forecasts of the global ...
