  • Description:
    "In February 1979, an east-coast cyclone developed which caused a very large snowfall to occur in the mid-Atlantic states. This impressive storm, called the President's Day storm, has been documented by Bosart (1981), and has been the basis for a number of numerical experiments with NMC prediction models. The storm was employed by Newell (1981) in his study of the impact of sensible and latent heat transfer from the sea upon the performance of an experimental ten-layer version of the LFM model, and by Deaven in his evaluation of a new moist convection parameterization system. Recently we completed a series of numerical experiments using a variety of versions of the LFM model in order to isolate the relative importance of resolution and physical process parameterizations in the prediction of this storm. It is the objective of this paper to document the results obtained and to propose a line of development which seems to flow from these results"--Introduction.
