RISA Severe Windstorm in the Lee of the Cascade Mountains of Washington State
Publisher: American Meteorological Society
Abstract: This paper describes a severe, leeside windstorm that struck parts of western Washington State on 23?25 December 1983. It is shown that strong winds, some exceeding 50 m s?1, were mainly limited to swaths downwind of gaps ...
A Case Study of Explosive Cyclogenesis in the Eastern Pacific
Publisher: American Meteorological Society
Abstract: An explosive cyclogenesis that occurred in the eastern Pacific on 13 November 1981 is described and discussed on the basis of surface and upper air analyses and satellite imagery. During one 12-h period the storm deepened ...
Coastal Southerlies and Alongshore Surges of the West Coast of North America: Evidence of Mesoscale Topographically Trapped Response to Synoptic Forcing
Publisher: American Meteorological Society
Abstract: One of the most important warm season weather phenomena of the west coast of North America is the temporal transition from northerly to southerly flow within a few hundred kilometers offshore from the coastal mountains. ...
Origin of the Catalina Eddy
Publisher: American Meteorological Society
Abstract: During late springs through early fall the normal regime of low-level westerly and northwesterly flow within the bight of southern California is occasionally interrupted by periods of southerly flow, elevated marine layers, ...
Frontal Structure in the Interior of an Intense Mature Ocean Cyclone
Publisher: American Meteorological Society
Abstract: Low-level (300 m) aircraft observations, taken within an intense extratropical storm during Intensive Observation Period 2 of the Experiment on Rapidly Intensifying Cyclones over the Atlantic, are used to document the ...
A New Look at Snowpack Trends in the Cascade Mountains
Publisher: American Meteorological Society
Abstract: This study examines the changes in Cascade Mountain spring snowpack since 1930. Three new time series facilitate this analysis: a water-balance estimate of Cascade snowpack from 1930 to 2007 that extends the observational ...
A Polar-Low Development over the Bering Sea: Analysis, Numerical Simulation, and Sensitivity Experiments
Publisher: American Meteorological Society
Abstract: A polar low that developed over the western Bering Sea on 7 March 1977 and tracked across St. Paul Island is investigated using observations and the Pennsylvania State University?National Center for Atmospheric Research ...
The Onshore Surge of Marine Air into the Pacific Northwest: A Coastal Region of Complex Terrain
Publisher: American Meteorological Society
Abstract: Many coastal locations around the world experience rapid transitions from warm, dry continental air to cool, moist marine air. These onshore ?pushes? or surges of marine air can be accompanied by strong winds, large ...
A Diagnostic Study of the Diurnal Rainfall Variation in the GATE B-Scale Area
Publisher: American Meteorological Society
Abstract: Heat and moisture budgets are used to compute net condensation rates in the GATE B-scale network for four hours of the day: 0000, 0600, 1200 and 1800 GMT. Budgets are presented for all phases combined, for selected periods ...
