The dispersion recorded at each station shows a wide range of values. Diurnal (10-15 st) and annual variations (20-25 si) are observed and correlations between dispersion and F. critical frequency and dispersion and magnetic disturbance are discussed. No association between dispersion and sunspot number was detected. The position of the \"ionospheric sources\" of the whistlers is of prime importance as dispersion varies with geomagnetic latitude. Much of the variation in dispersion observed by individual stations is believed to be due to their being able to \"see\" ionospheric sources up to 100 away.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380848661782874503","@type":"Researcher","foaf:name":[{"@value":"J Crouchley"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00049506"},{"@type":"EISSN","@value":"14465582"}],"prism:publicationName":[{"@value":"Australian Journal of Physics"}],"dc:publisher":[{"@value":"CSIRO Publishing"}],"prism:publicationDate":"1964-03-01","prism:volume":"17","prism:number":"1","prism:startingPage":"88","prism:endingPage":"105"},"reviewed":"false","dc:rights":["https://doi.org/10.1071/journalslicense"],"url":[{"@id":"https://connectsci.au/ph/article-pdf/17/1/88/1347362/ph640088.pdf"}],"createdAt":"2011-05-31","modifiedAt":"2025-11-05","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390001204374541952","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Study of Dispersion of Lightning Whistlers Observed by Akebono Satellite in the Earth's Plasmasphere"},{"@value":"Study of dispersion of lightning whistler observed by akebono satellite in the earth’s plasmasphere"}]},{"@id":"https://cir.nii.ac.jp/crid/2050870367050224896","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Statistical study on propagation characteristics of Omega signals (VLF) in magnetosphere detected by the Akebono satellite"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1071/ph640088"},{"@type":"CROSSREF","@value":"10.1587/transcom.e95.b.3472_references_DOI_OcioK6jhkqEJ4Bni7jcbEnT7mU3"},{"@type":"CROSSREF","@value":"10.1186/s40623-017-0684-5_references_DOI_OcioK6jhkqEJ4Bni7jcbEnT7mU3"}]}
