Abstract
A quantification of local energy propagation is employed to distinguish cases of downstream baroclinic development, as described by Orlanski and Sheldon (1995), from among 41 cold‐season cyclones that intensified strongly over the eastern North Pacific Ocean. A group of western North Pacific cyclones is employed to confirm that, in a composite sense, the eastern group is relatively less dependent on baroclinic conversion and more dependent on eddy energy that originates upstream. Based on a proposed set of criteria, about half of the individual eastern cyclones are found to be good examples of downstream baroclinic development. Almost all of this subset appears to have been influenced by a propagation of eddy energy from separate cyclones developing over the western North Pacific a day or two earlier. A primary source of energy feeding this propagation appears to be ascent in the warm sector of the upstream cyclones.
