Abstract : A developing surface frontal system with an overlying polar front jet and subtropical jet stream merging region was present over the continental United States during 22 to 24 March, 1966. Possible crossover flow between these two jet streams has been studied in detail by isentropic air trajectories at four potential temperature levels from 310 K to 335 K. The results of the trajectory analyses on the four theta surfaces have indicated a crossover of air parcels from the subtropical jet stream to the polar front jet stream. No evidence has been found for a reciprocal relationship for air parcels initially associated with the polar front jet between 310 K and 335 K isentropic levels. (Author)
