Comparison of the long‐period pulsations (in the <jats:italic>Pc</jats:italic>5 frequency range) observed on the ground to the solar wind velocity and solar wind pressure observed by the WIND satellite confirms previous results that high solar wind velocity correlates well with increased <jats:italic>Pc</jats:italic>5 power. Although some variability was evident among the five storms, solar wind pressure and variability in velocity or pressure exhibited considerably weaker correlations. Each storm exhibited narrow‐band <jats:italic>Pc</jats:italic>5 wave activity during the recovery phase, but only in the dawn‐noon sector at each site. During the main phase, and at all other local times during the recovery phase, wave activity was broadband. The strongest <jats:italic>Pc</jats:italic>5 power was observed at frequencies above 2 mHz at stations in the auroral zone and poleward and below 2 mHz at stations at middle and low latitudes. Comparison to published time profiles of energetic electrons at geosynchronous orbit suggests that if ULF wave activity is responsible for the initial energization of these electrons, broadband activity rather than narrowband (<jats:italic>Pc</jats:italic>5) waves must play the dominant role. Our data cannot rule out, however, the importance of narrowband waves in providing additional energization during the recovery phase.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380285711829381380","@type":"Researcher","foaf:name":[{"@value":"J.
