RISSignificant Events of Interhemispheric Atmospheric Mass Exchange: Composite Structure and Evolution
Publisher: American Meteorological Society
Abstract: The various modes of atmospheric mass redistribution characterize the principal variations of the general circulation of the atmosphere. Interhemispheric exchanges of atmospheric mass occur with considerable regularity on ...
The Canadian Land Data Assimilation System (CaLDAS): Description and Synthetic Evaluation Study
Publisher: American Meteorological Society
Abstract: he Canadian Land Data Assimilation System (CaLDAS) has been developed at the Meteorological Research Division of Environment Canada (EC) to better represent the land surface initial states in environmental prediction and ...
Southeast Asian Pressure Surges and Significant Events of Atmospheric Mass Loss from the Northern Hemisphere, and a Case Study Analysis
Publisher: American Meteorological Society
Abstract: A recent study of significant events of atmospheric mass depletion from the Northern Hemisphere (NH) during the extended boreal winter indicated that Southeast Asian pressure surges were an important physical mechanism ...
Observational Study of Wind Channeling within the St. Lawrence River Valley
Publisher: American Meteorological Society
Abstract: The presence of orography can lead to thermally and dynamically induced mesoscale wind fields. The phenomenon of channeling refers to the tendency for the winds within a valley to blow more or less parallel to the valley ...
Influence of open water bodies on the modelling of summertime convection over the Canadian Prairies
Publisher: American Meteorological Society
Abstract: here are numerous water features on the Canadian landscapes that are not monitored. Specifically, there are water bodies over the prairies and Canadian shield regions of North America that are ephemeral in nature and could ...
A Numerical Case Study of Secondary Marine Cyclogenesis Sensitivity to Initial Error and Varying Physical Processes
Publisher: American Meteorological Society
Abstract: Secondary cyclogenesis has been identified as a difficult forecast challenge. In this paper, the authors examine the dominant physical processes associated with the predictability of a case of explosive secondary marine ...
Evaluation of Snowpack Simulations over the Canadian Rockies with an Experimental Hydrometeorological Modeling System
Publisher: American Meteorological Society
Abstract: To improve the representation of the land surface in their operational numerical weather prediction (NWP) models, the Meteorological Research Division of Environment Canada (EC) is developing an external hydrometeorological ...
Warm Season Evaluation of Soil Moisture Prediction in the Soil, Vegetation, and Snow (SVS) Scheme
Publisher: American Meteorological Society
Abstract: new land surface scheme has been developed at Environment and Climate Change Canada (ECCC) to provide surface fluxes of momentum, heat, and moisture for the Global Environmental Multiscale (GEM) atmospheric model. In this ...
Field-Scale Spatial Variability of Soil Moisture and L-Band Brightness Temperature from Land Surface Modeling
Publisher: American Meteorological Society
Abstract: lthough soil moisture is an essential variable within the Earth system and has been extensively investigated, there is still a limited understanding of its spatiotemporal distribution and variability. Thus, the objective ...
The Pan-Canadian High Resolution (2.5 km) Deterministic Prediction System
Publisher: American Meteorological Society
Abstract: ince November 2014, the Meteorological Services of Canada (MSC) has been running a real-time numerical weather prediction system that provides deterministic forecasts on a regional domain with a 2.5-km horizontal grid ...
