As the cold air passes over the unfrozen, and relatively warm waters of the Great Lakes, warmth and moisture is transferred into the lowest portion of the atmosphere. The air becomes warmer and less dense than the overriding cold air, so it rises. The rising air ultimately leads to cloudiness and snow on the leeward sides of the Great Lakes. A conceptual model has been developed highlighting these concepts. LES typically takes the form of discrete, narrow bands (see radar example). These bands are often characterized by intense snowfall, and limited visibility. One unique aspect of LES is the extreme variability that can occur in space and time.

In addition to its serious health consequences, obesity has real economic costs that affect all of us. The estimated annual health care costs of obesity-related illness are a staggering $190.2 billion or nearly 21% of annual medical spending in the United States.
