RISTesting the Effects of a New Land Surface Scheme and of Initial Soil Moisture Conditions in the Canadian Global Forecast Model
Publisher: American Meteorological Society
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 ...
Offline implementation and evaluation of the Canadian Small Lake Model with the Canadian Land Surface Scheme over western Canada
Publisher: American Meteorological Society
Abstract: he Canadian Small Lake Model (CSLM), version 2, was run with the Canadian Land Surface Scheme (CLASS), version 3.6.1, in an offline regional test over western Canada. Forcing data were derived from ERA-Interim reanalyses, ...
Evaluation of CLASS Snow Simulation over Eastern Canada
Publisher: American Meteorological Society
Abstract: he Canadian Land Surface Scheme (CLASS), version 3.6.1, was run offline for the period 1990?2011 over a domain centered on eastern Canada, driven by atmospheric forcing data dynamically downscaled from ERA-Interim using ...
Wintertime Simulations of a Boreal Lake with the Canadian Small Lake Model
Publisher: American Meteorological Society
Abstract: AbstractA one-dimensional mixed layer dynamic lake model is enhanced with snow and ice physics for an examination of processes governing ice cover and phenology in a small boreal lake. The complete snowpack physics module ...
Effects of Spatial Aggregation of Initial Conditions and Forcing Data on Modeling Snowmelt Using a Land Surface Scheme
Publisher: American Meteorological Society
Abstract: Small-scale topography and snow redistribution have important effects on snow-cover heterogeneity and the timing, rate, and duration of spring snowmelt in mountain tundra environments. However, land surface schemes (LSSs) ...
Snow Cover and Snow Mass Intercomparisons of General Circulation Models and Remotely Sensed Datasets
Publisher: American Meteorological Society
Abstract: Confirmation of the ability of general circulation models (GCMs) to accurately represent snow cover and snow mass distributions is vital for climate studies. There must be a high degree of confidence that what is being ...
Soil Moisture Memory in AGCM Simulations: Analysis of Global Land–Atmosphere Coupling Experiment (GLACE) Data
Publisher: American Meteorological Society
Abstract: Soil moisture memory is a key aspect of land?atmosphere interaction and has major implications for seasonal forecasting. Because of a severe lack of soil moisture observations on most continents, existing analyses of ...
GLACE: The Global Land–Atmosphere Coupling Experiment. Part I: Overview
Publisher: American Meteorological Society
Abstract: The Global Land?Atmosphere Coupling Experiment (GLACE) is a model intercomparison study focusing on a typically neglected yet critical element of numerical weather and climate modeling: land?atmosphere coupling strength, ...
GLACE: The Global Land–Atmosphere Coupling Experiment. Part II: Analysis
Publisher: American Meteorological Society
Abstract: The 12 weather and climate models participating in the Global Land?Atmosphere Coupling Experiment (GLACE) show both a wide variation in the strength of land?atmosphere coupling and some intriguing commonalities. In this ...
