Examples of Enhanced Global Solar Radiation Through Multiple Reflection from an Ice-Covered Arctic Sea
Publisher: American Meteorological Society
Abstract: Three years of simultaneous measurements of incoming and reflected solar radiation for adjacent snow-free land and ice-covered sea surfaces along the Hudson Bay coastline indicate that multiple reflection enhancement can ...
The Energy Budget of Canadian Shield Subarctic Terrain and Its Impact on Hillslope Hydrological Processes
Publisher: American Meteorological Society
Abstract: The objective of the study is to determine the local processes that control the partitioning of the energy budget of shield terrain in the western Canadian subarctic. The magnitude of the spring snowmelt and its potential ...
Moisture and Temperature Limits of the Equilibrium Evapotranspiration Model
Publisher: American Meteorological Society
Abstract: Energy balance measurements of evapotranspiration from a developing corn crop are compared with daily equilibrium evapotranspiration estimates to examine the accuracy of the model and the environmental conditions under ...
A Simple Model for Determining Evaporation from High-Latitude Upland Sites
Publisher: American Meteorological Society
Abstract: Energy-budget calculations and equilibrium, model estimates of evaporation from a lichen-dominated upland site in the Hudson Bay lowlands are presented. The energy-budget calculations reveal that the lichen surface is ...
A Comparison of Sensible and Latent Heat Flux Calculations Using the Bowen Ratio and Aerodynamic Methods
Publisher: American Meteorological Society
Abstract: An analysis technique is outlined that calculates the sensible and latent heat fluxes by the Bowen ratio and aerodynamic methods, using profile measurements at any number of heights. Field measurements at two sites near ...
Substantiation of the Priestley and Taylor Parameter α = 1.26 for Potential Evaporation in High Latitudes
Publisher: American Meteorological Society
Abstract: Summertime latent heat flux values determined by the energy budget approach are compared to equilibrium model estimates for two shallow lakes and two sedge meadow surfaces in northern Canada. Comparison of energy budget ...
Thermal Characteristics and Energy Balance of Various-Size Canadian Shield Lakes in the Mackenzie River Basin
Publisher: American Meteorological Society
Abstract: This study addresses the thermal and energy budget characteristics of four different-size Canadian Shield lakes in the Mackenzie River basin during the ice-free season of 2000. The objectives are to characterize and compare ...
Improving Computation of Sensible Heat Flux over a Water Surface Using the Variational Method
Publisher: American Meteorological Society
Abstract: In this study, the authors have performed the variational computations for surface sensible heat fluxes over a large northern lake using observed wind, temperature gradient, and moisture gradient. In contrast with the ...
Enhancement of Evaporation from a Large Northern Lake by the Entrainment of Warm, Dry Air
Publisher: American Meteorological Society
Abstract: The turbulent exchange of water vapor and heat were measured above Great Slave Lake, Northwest Territories, Canada, using the eddy covariance method for most of the ice-free period in 1997, 1998, and 1999. In all years, ...
Energy Budget Processes of a Small Northern Lake
Publisher: American Meteorological Society
Abstract: There is a paucity of information on the energy budget of Canada's northern lakes. This research determines processes controlling the magnitude of energy fluxes between a small Canadian Shield lake and the atmosphere. ...
