Observations are compared with the ionospheric parameter obtained at the same station and random scintillation records. The results indicate that the quasi‐periodic scintillations are most likely produced by plasma blobs within the sporadic <jats:italic>E</jats:italic> layers. Discussion focuses on characteristics of the ringing pattern which precedes and follows the primary deep fade‐out, in field strength. In the majority of events the ringing pattern tends to develop after the distinct deep fade‐out, i.e., the pattern is asymmetric. Quasi‐periodic scintillation patterns are produced by the movement of plasma blobs in the case of geostationary satellite experiments. Thus the shape of the blob must be deformed so that a steep density gradient is attained on the backside. When the blob is highly deformed by the plasma instability which grows at the steep density gradient, burstlike random scintillations may be produced by the blob.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418520074791808","@type":"Researcher","foaf:name":[{"@value":"Takashi Maruyama"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00486604"},{"@type":"EISSN","@value":"1944799X"}],"prism:publicationName":[{"@value":"Radio Science"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1991-05","prism:volume":"26","prism:number":"3","prism:startingPage":"691","prism:endingPage":"700"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F91RS00357"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/91RS00357"}],"createdAt":"2008-04-28","modifiedAt":"2023-09-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050025031478815104","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Morphology and dynamics of daytime mid-latitude sporadic-E patches revealed by GPS total electron content observations in Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1050869456409434496","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Two-dimensional observations of midlatitude sporadicEirregularities with a dense GPS array in Japan"},{"@value":"Two-dimensional observations of midlatitude sporadic<i>E</i>irregularities with a dense GPS array in Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360302865721629952","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Anomalous Long‐Distance Propagation of ILS LOC Signals by the Es Layer and Its Impact on Aviation Receivers"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/91rs00357"},{"@type":"CROSSREF","@value":"10.1029/2023sw003577_references_DOI_Yu3q95XOSJt9IjaSnx0bgpCiwVg"},{"@type":"CROSSREF","@value":"10.1002/2013rs005295_references_DOI_Yu3q95XOSJt9IjaSnx0bgpCiwVg"},{"@type":"CROSSREF","@value":"10.1186/s40623-015-0257-4_references_DOI_Yu3q95XOSJt9IjaSnx0bgpCiwVg"}]}
