The Propagation of Mountain Waves into the Stratosphere: Quantitative Evaluation of Three-Dimensional Simulations
Publisher: American Meteorological Society
Abstract: On 6 January 1992 measurements of a mountain wave with significant amplitude were taken over the southern tip of Greenland during an ER-2 flight at an altitude of about 20 km. This work focuses on 3D numerical simulations ...
The German Front Experiment 1987
Publisher: American Meteorological Society
Abstract: The German Front Experiment, 1987 (GFE87) is a field experiment using aircraft, radar, surface, and upper-air observations to determine the influence of the European Alps on cold fronts. Measurements are concentrated in ...
Potential Vorticity of Flow along the Alps
Publisher: American Meteorological Society
Abstract: Observations from the German Front Experiment are presented here that show the existence?in conditions with a dominant flow component parallel to the main Alpine chain?of a mesoscale region to the north of the Alps where ...
The Bjerknes' Circulation Theorem: A Historical Perspective
Publisher: American Meteorological Society
Abstract: Two lines of thinking concerning fluid rotation?using either vorticity or circulation?emerged from the nineteenth-century work of Helmholtz and Thomson (Lord Kelvin), respectively. Vilhelm Bjerknes introduced an extension ...
Defender and Expositor of the Bergen Methods of Synoptic Analysis: Significance, History, and Translation of Bergeron’s (1928) “Three-Dimensionally Combining Synoptic Analysis”
Publisher: American Meteorological Society
Abstract: Tor Bergeron was a key member of the Bergen School of Meteorology that developed some of the most influential contributions to synoptic analysis in the 20th century: air-mass analysis, polar-front theory, and the Norwegian ...
Mountain Waves over Mont Blanc: Influence of a Stagnant Boundary Layer
Publisher: American Meteorological Society
Abstract: A stationary mountain wave, embedded in southwesterly flow over Mont Blanc in the Alps, was observed simultaneously by three research aircraft and three types of remote sensing: GPS dropsondes, airborne light detecting and ...
Tor Bergeron’s Defense of Bergen Methods for Synoptic Analysis: Overcoming Resistance to Airmass and Frontal Analyses
Publisher: American Meteorological Society
Extratropical Cyclones: A Century of Research on Meteorology’s Centerpiece
Publisher: American Meteorological Society
Abstract: The year 1919 was important in meteorology, not only because it was the year that the American Meteorological Society was founded, but also for two other reasons. One of the foundational papers in extratropical cyclone ...
MAP D-PHASE: Real-Time Demonstration of Weather Forecast Quality in the Alpine Region
Publisher: American Meteorological Society
Abstract: Demonstration of probabilistic hydrological and atmospheric simulation of flood events in the Alpine region (D-PHASE) is made by the Forecast Demonstration Project in connection with the Mesoscale Alpine Programme (MAP). ...
