RISOn the Use of Time-Offset Model Output Statistics for Production of Surface Wind Forecasts
Publisher: American Meteorological Society
Abstract: An operational model output statistics (MOS) surface wind forecasting procedure has been implemented recently for 159 Canadian stations. Though the system has much in common with MOS wind forecast procedures in the United ...
A diagnostic Study of Atmospheric Spectral Kinetic Energetics
Publisher: American Meteorological Society
Abstract: Wind spectra are obtained from data using expansions in spherical harmonies. Equations governing the tendencies of total kinetic energy of the spectral wind components are derived. Dissipation is obtained diagnostically ...
Objective Guidance for 0–24-Hour and 24–48-Hour Mesoscale Forecasts of Lake-Effect Snow Using CART
Publisher: American Meteorological Society
Abstract: Lake-effect-snow-possible (LESP) days were identified for each of 29 climatological stations in the lee of Lake Huron and Georgian Bay for the November-to-April winters of 1984?1988, using 0?24-h and 24?48-h wind and ...
CART Regression Models for Predicting UV Radiation at the Ground in the Presence of Cloud and Other Environmental Factors
Publisher: American Meteorological Society
Abstract: The goal was to build models for predicting ground-level biologically weighted ultraviolet radiation (UV index, shortened to UV here) that would not require substantial execution time in weather and climate models and yet ...
Blizzard Conditions in the Canadian Arctic: Observations and Automated Products for Forecasting
Publisher: American Meteorological Society
The Use of Routine Weather Observations to Calculate Liquid Water Content in Summertime High-Elevation Fog
Publisher: American Meteorological Society
Abstract: This paper represents a stage within a larger project to estimate acid ion deposition from cloud impacting on high-elevation forests. Acid ion deposition depends principally on three factors: the liquid water content (LWC), ...
A Strategy for Verification of Weather Element Forecasts from an Ensemble Prediction System
Publisher: American Meteorological Society
Abstract: Using a Bayesian context, new measures of accuracy and skill are proposed to verify weather element forecasts from ensemble prediction systems (EPSs) with respect to individual observations. The new scores are in the form ...
Warm Season Lightning Probability Prediction for Canada and the Northern United States
Publisher: American Meteorological Society
Abstract: Statistical models valid May?September were developed to predict the probability of lightning in 3-h intervals using observations from the North American Lightning Detection Network and predictors derived from Global ...
On the Surface-Convection Feedback during Drought Periods on the Canadian Prairies
Publisher: American Meteorological Society
Abstract: inkages between the terrestrial ecosystem and precipitation play a critical role in regulating regional weather and climate. These linkages can manifest themselves as positive or negative feedback loops, which may either ...
Impacts of Land–Atmosphere Feedbacks on Deep, Moist Convection on the Canadian Prairies
Publisher: American Meteorological Society
Abstract: he purpose of this study was to focus on how anomalies in the normalized difference vegetation index (NDVI; a proxy for soil moisture) over the Canadian Prairies can condition the convective boundary layer (CBL) so as to ...
