On Adding Thermodynamic Damping Mechanisms to Refine Two Classical Models of Katabatic Winds
Publisher: American Meteorological Society
Abstract: he Prandtl and layer-averaged models of katabatic winds contain some nonphysical singularities in the analytical solutions, which give unbounded steady flow anomalies at zero slope angles or adiabatic lapse rates. This ...
Efficient Algorithms for Maximum Covariance Analysis of Datasets with Many Variables and Fewer Realizations: A Revisit
Publisher: American Meteorological Society
Abstract: Fast and reliable algorithms for maximum covariance analysis (MCA) are investigated. The traditional algorithm based on the direct singular value decomposition (SVD) of a covariance matrix is computationally expensive for ...
Statistical–Dynamical Seasonal Prediction Based on Principal Component Regression of GCM Ensemble Integrations
Publisher: American Meteorological Society
Abstract: A statistical approach to correct a dynamical ensemble forecast of future seasonal means based on the past performance of a general circulation model (GCM) is formulated. The approach combines principal component (PC) ...
Impact of the Madden–Julian Oscillation on Wintertime Precipitation in Canada
Publisher: American Meteorological Society
Abstract: Based on the adjusted daily total precipitation data at Canadian stations and the Climate Prediction Center Merged Analysis of Precipitation (CMAP) data during the most recent 30 Northern Hemisphere winters, the connection ...
Application Potential of Four Nontraditional Similarity Metrics in Hydrometeorology
Publisher: American Meteorological Society
Abstract: his paper presents a review and assessment of four nontraditional similarity metrics that can be applied to hydrological and meteorological data. These metrics are 1) the uncentered correlation coefficient, 2) the ...
Classification and Conceptual Models for Heavy Snowfall Events over East Vancouver Island of British Columbia, Canada
Publisher: American Meteorological Society
Abstract: he East Vancouver Island region on the west coast of Canada is prone to heavy snow in winter due to its unique geographical setting, which involves complicated interactions among the atmosphere, ocean, and local topography. ...
A Case Study of Processes Impacting Precipitation Phase and Intensity during the Vancouver 2010 Winter Olympics
Publisher: American Meteorological Society
Abstract: ccurate forecasting of precipitation phase and intensity was critical information for many of the Olympic venue managers during the Vancouver 2010 Olympic and Paralympic Winter Games. Precipitation forecasting was complicated ...
