Abstract

The number and location of stagnation days within the eastern United States, as estimated mainly from a surface geostrophic-wind criterion, is presented by month and for the year 1981 as a whole. In 1981, the number of stagnation days exceeded the 40-year average everywhere except Florida, with a maximum frequency of occurrence somewhat to the west and north of the usual location. There were unique occurrences of stagnation in a belt extending from Minnesota to Maine, including extreme southeastern Canada.
