Four distinct Northeast US heat wave circulation patterns and associated mechanisms, trends, and electric usage

Abstract Northeastern US heat waves have usually been considered in terms of a single circulation pattern, the high-pressure circulation typical of most heat waves occurring in other parts of the world. However, k-means clustering analysis from 1980–2018 shows there are four distinct patterns of Nor...
