Abstract: The forty-day Wangara data set is used to discuss the applicability of the traditional formulations for the surface fluxes for atmospheric circulation models. It is shown that, while in unstable conditions the surface layer ...

Abstract: A parameterization of the surface nocturnal inversion of temperature is proposed to enable atmospheric circulation models to handle the surface energy budget without having to resolve the boundary layer. The scheme allows ...

Abstract: The intensity of vertical mixing in atmospheric models generally depends on wind shear and static stability, making the diffusion process nonlinear. Traditional implicit numerical schemes, which treat the variables to be ...

Abstract: A new land surface scheme developed for the Canadian general circulation model has been introduced into the Canadian global forecast model and tested for a summer case. It features three soil layers, a snow layer, and a ...

Abstract: A numerical model to forecast road conditions, Model of the Environment and Temperature of Roads (METRo), has been developed to run at Canadian weather centers. METRo uses roadside observations from road weather information ...

Abstract: This study examines the linearization properties of a simplified planetary boundary layer parameterization based on the vertical diffusion equations, in which the exchange coefficients are a function of the local Richardson ...

Abstract: The summertime improvement resulting from the operational implementation of a new surface modeling and assimilation strategy into the Canadian regional weather forecasting system is described in this study. The surface ...

Abstract: Many studies have demonstrated the importance of land surface schemes in climate change studies using general circulation models (GCMs). However, there have not been many studies that explore the role of land surface schemes ...
