The Behavior of Jet Streams over Eastern North America during January and February 1948

Article English OPEN
Phillips, Norman A. (2011)

A graph of the latitude of jet streams at 80° W longitude for a 49-day period in the winter of 1947–8 shows that the jet stream undergoes changes which appear as discontinuities on such a graph. Several cases are discussed which illustrate the manner in which these discontinuities appear. The new jets so formed then appear to experience a southward displacement before their disappearance. Accompanying the southward displacement at this longitude is a disappearance of the solenoidal field accompanying the jet in the lower troposphere, and an increase of the potential temperature in the center of the jet.DOI: 10.1111/j.2153-3490.1950.tb00320.x
