Diurnal Variations of Lake Effect Precipitation

Lake effect precipitation plays an important role in the climatology of western New York. Significant precipitation due to the winter lake effect can cause poor visibility and deteriorating travel conditions that result in societal impacts. The timing of such lake effect events is of critical importance to local municipalities, schools, airports, and utility workers. It is unclear to date whether lake effect precipitation has a preferred time of day. Of additional interest is whether large scale weather systems display a preferential timing when they pass over the Great Lakes. Hourly precipitation data gathered from the National Climatic Data Center during the lake effect season (October-March) from 1948-2006 will be used to create histograms of the hourly distribution of lake effect precipitation. Reanalysis data will be examined for the corresponding time periods to classify events as either lake effect or lake enhanced precipitation events.
