Abstract: The structure and development of idealized short mesoscale baroclinic waves are investigated within the framework of several numerical simulations. The numerical model used in this study is a mesoscale version of Clark's ...

Abstract: One year of precipitation records taken from a subset of the World Meteorological Organization (WMO) global rain gauge network has been analyzed. This analysis has shown that the distribution of accumulation of precipitation ...

Abstract: A cloud chemistry model is formulated in term of continuity equations for chemical species in the aqueous and aqueous phases within the cloud. The model includes scavenging of SO2, HNO3, HN3, H2O3, and sulphate aerosol ...

Abstract: To improve forecasts of various weather elements (snow, rain, and freezing precipitation) in numerical weather prediction models, a new mixed-phase cloud scheme has been developed. The scheme is based on a single prognostic ...

Abstract: To improve cloud and precipitation forecasts in the Canadian numerical weather prediction system, three cloud schemes with various degrees of complexity are evaluated. Several winter cases are simulated and mesoscale ...

Abstract: Comparisons have been made between in situ aircraft measurements of integrated liquid water and retrievals of integrated liquid water path (LWP) from algorithms using SSM/I brightness temperatures. The aircraft measurements ...

Abstract: The three-dimensional Canadian Mesoscale Compressible Community model has been run at high resolution (?x = 2 km, ?z = 50 m) to simulate stratus clouds observed on 1 September 1995 during the Radiation, Aerosol and Cloud ...

Abstract: In order to provide guidance for the further improvement of a mixed-phase cloud scheme being developed for use in an NWP model, comparisons of dynamical, thermodynamical, and microphysical variables between in situ aircraft ...

Abstract: In situ aircraft measurements, collected during three research projects, are used to compare forecasts from three explicit cloud schemes. These schemes include the Canadian operational Sundqvist (SUND) scheme, the Tremblay ...

Abstract: A technique for the detection of supercooled liquid water (SLW) from Special Sensor Microwave/ (SSM/I) data is discussed. For this study, these SLW retrievals depict areas of icing that are used to compare against different ...
