RISA Finite-Element Model of the Atmospheric Boundary Layer Suitable for Use with Numerical Weather Prediction Models
Publisher: American Meteorological Society
Abstract: We give a detailed description of an atmospheric boundary layer model capable of simulating the diurnal cycles of wind, temperature and humidity. The model includes a formulation of various physical processes (radiative ...
Numerical Forecasts of Explosive Winter Storms: Sensitivity Experiments with a Meso‐α scale Model
Publisher: American Meteorological Society
Abstract: Mesoscale numerical forecasts of cases of explosive cyclogenesis during the Canadian Atlantic Storms Program are presented in order to examine the evolution and structure of the simulated storms, and to assess the model's ...
Inclusion and verification of a predictive Cloud-Water Scheme in a Regional Numerical Weather Prediction Model
Publisher: American Meteorological Society
Abstract: The implementation of a predictive cloud-water scheme in a regional finite-element weather prediction model is presented. The model employed in this study includes efficient and accurate numerical techniques and is equipped ...
Inclusion of a TKE Boundary Layer Parameterization in the Canadian Regional Finite-Element Model
Publisher: American Meteorological Society
Abstract: The formulation of the regional model recently implemented by the Atmospheric Environment Service of Canada for its operational 48 h NWP forecasts is presented. The emphasis is put on the parameterization of the physical ...
Examination of the Impact of a Coupled Atmospheric and Ocean Wave System. Part I: Atmospheric Aspects
Publisher: American Meteorological Society
Abstract: To take into account the change of surface roughness length induced by ocean waves, a coupled atmospheric and ocean wave model system is developed. A two-way coupling is done between a mesoscale atmospheric model, MC2, and ...
Evaluation of the Town Energy Balance Model in Cold and Snowy Conditions during the Montreal Urban Snow Experiment 2005
Publisher: American Meteorological Society
Abstract: Using the Montreal Urban Snow Experiment (MUSE) 2005 database, surface radiation and energy exchanges are simulated in offline mode with the Town Energy Balance (TEB) and the Interactions between Soil, Biosphere, and ...
