The Meteorological Aspects of Ice Cover on the Great Lakes*
The formation and break-up of ice on the Great Lakes as observed by regular ice reconnaissance flights conducted by the Meteorological Service of Canada is discussed in terms of the meteorological parameters involved. Ice cover on the individual lakes over the past four years is correlated with the winter temperature regime and an index of the heat stored in each lake using the concept of cumul...
متن کاملSatellite SAR Remote Sensing of Great Lakes Ice Cover, Part 2. Ice Classification and Mapping
During the 1997 winter season, shipborne polarimetric backscatter measurements of Great Lakes (freshwater) ice types using the Jet Propulsion Laboratory C-band scatterometer, together with surface-based ice physical characterization measurements and environmental parameters, were acquired concurrently with Earth Resource Satellite 2 (ERS-2) and RADARSAT Synthetic Aperture Radar (SAR) data. This...
متن کاملTemporal and Spatial Variability of Great Lakes Ice Cover, 1973â•fi2010
In this study, temporal and spatial variability of ice cover in the Great Lakes are investigated using historical satellite measurements from 1973 to 2010. The seasonal cycle of ice cover was constructed for all the lakes, including Lake St. Clair. A unique feature found in the seasonal cycle is that the standard deviations (i.e., variability) of ice cover are larger than the climatological mea...
متن کاملSensitivity of Lake-Effect Snowfall to Lake Ice Cover and Temperature in the Great Lakes Region
High-resolution Weather Research and Forecasting Model (WRF) simulations are used to explore the sensitivity ofGreat Lakes lake-effect snowfall (LES) to changes in lake ice cover and surface temperature.A control simulation with observed ice cover is compared with three sensitivity tests: complete ice cover, no lake ice, and warmer lake surface temperatures. The spatial pattern of unfrozen lake...
متن کاملThermal simulation of a lake with winter ice cover’
A one-dimensional thermodynamic model of a two-component ice and snow cover is added to an existing one-dimensional lake mixing model. Emphasis is placed on the thermodynamic coupling between the ice and mixing models-absent in previous models. The two-dimensional effects of partial ice cover are incorporated into this one-dimensional framework by using a minimum ice thickness. The model is app...
