It has been found that the level of yearly maximum of the occurrence rate has changed with such a regular way that at each station the level began to rise after the last sunspot maximum period, but the higher the latitude the sooner the level turned to fall, since then it has continued falling. It is suggested that these annual variations may be qualitatively explained from following three points: 1. variation in polar creep characteristics for whistler propagation caused by increase of gradient of electron density against height in the upper atmosphere, 2. fall of whistler propagation through duct of field alinged electron distribution, and 3. change of inclination of ionospheric layer. In order to conclude it is necessary to make more whistler ray path tracing by theoretical calculation and compare the results with observational one.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/21803"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学空電研究所","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0465-7756","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大津, 仁助","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"57737","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩井, 章","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"57738","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中, 義人","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"57739","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"OUTSU, Jinsuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"57740","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IWAI, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"57741","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TANAKA, Yoshihito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"57742","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-21"}],"displaytype":"detail","filename":"bulria_13_1-2_11.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bulria_13_1-2_11.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/19757/files/bulria_13_1-2_11.pdf"},"version_id":"90ae27a1-9156-4be6-b17d-18b1b2044ca9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"中低緯度帯に於ける1957年7月以後のホイッスラーの発生頻度の変化について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中低緯度帯に於ける1957年7月以後のホイッスラーの発生頻度の変化について","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1723"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-07"},"publish_date":"2015-05-07","publish_status":"0","recid":"19757","relation_version_is_last":true,"title":["中低緯度帯に於ける1957年7月以後のホイッスラーの発生頻度の変化について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-26T06:48:16.268763+00:00"}
