Abstract: The Mackenzie River basin (MRB) in northwestern Canada is a climatologically important region that exerts significant influences on the weather and climate of North America. The region exhibits the largest cold-season ...

Abstract: A two-dimensional, anelastic, cloud-resolving numerical model was used to simulate squall systems. Large domain and fine grid resolutions were utilized so that both the convective and mesoscale components of squall lines ...

Abstract: The effects of various microphysical processes and the Coriolis force on the dynamics of squall systems were investigated with a two-dimensional, anelastic numerical model. The incorporation of ice-phase microphysics into ...

Abstract: The physical processes involved in the evolution of the model squall line presented in Part I of this study are examined. It is found that both the thermal and dynamic effects are important in the development of the midlevel ...

Abstract: Various authors have proposed that the cooling associated with melting precipitation contributes significantly to the dynamics of mesoscale precipitation systems. In this study, we use the numerical model described in Part ...

Abstract: The melting of snow extracts latent heat of fusion from the environment. The basic response of the atmosphere to this cooling-by-melting mechanism is investigated by using a nonlinear two-dimensional numerical model. It ...

Abstract: The 54-yr (1948?2001) NCEP?NCAR reanalysis data as well as other information were used to study the moisture transport and associated circulation features for the severe 2000/01 drought over the western and central Canadian ...

Abstract: On 30 September 1994 an Arctic low pressure system passed over the southern Beaufort Sea area of northern Canada and research aircraft observations were made within and around the warm front of the storm. This study is ...
