Miller classification

The Miller classification is a technique that meteorologists use to classify nor'easters. The system splits nor'easters into five categories: Miller A, Miller B, Miller C, Miller D, and Miller E; the classification system initially started out with the first two categories. The system was derived by meteorologist and researcher J.E. Miller in 1946, (not to be confused with R.C. Miller, the Air Force meteorologist who, in 1948, made the world's first successful tornado forecast).
