It has been studied further in this paper, the fine structure of the leader discharge type wave-forms from cumulo-nimbus which has grown up to a stage just before a thunder-cloud, the wave-forms from cloud to earth discharges, and the main discharge type wave-forms in calm days. Widths of pulses of differential type wave-form and their intervals of occurrence, of which a leader discharge type wave-train is constructed, are found to have their most frequent values of about 60 micro-seconds and 250-350 micro-seconds respectively. A statistical investigation of these pulses produced by intra-cloud discharge in cumulo-nimbus shows that the stepped leader like character of them corresponds unlikely to the stepped leader stroke as in the case of the cloud to earth discharge, but represents presumably the small local separate dart leader like sub-discharges which are simultaneously superposed upon the violent main cloud discharge of stepped leader character. The analysis of clear pulsive wave trains, which correspond to the cloud to earth discharge that occurred within several hundred metres from the observation station, shows the similar values of pulse interval and pulse width to those of intra-cloud discharge in the earlier stage. The interval of pulses reduces to 30-60 micro-seconds in the later stage, but the pulse width on the other hand does not reduce so evidently as pulse interval. Although the authors assume that these recorded wave trains are produced from the first leader stroke of this lightning, it is not evident at present the reason why the intervals are larger and the pulse width has the measurable value of more than several ten micro-seconds in the earlier stage. The simultaneous observation of lightning and corresponding discharge wave-form shows that the first large pulse of the main discharge type wave-form, which corresponds to cloud to earth discharge, should be interpreted as to be emitted from the main part of return stroke of the corresponding cloud to earth lightning. Comparison between the wave-forms of main discharge type in calm days and those obtained during thunder-storms, which correspond perhaps both to cloud to earth discharge and to intra-cloud discharge of special type, indicates that the main discharge type wave-form in calm days does not always interpreted as to be emitted from the return stroke of a cloud to earth lightning, but some times may be interpreted as to be radiated from a special type discharge in the cloud.","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/2237/21470"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Research Institute of Atmospherics, Nagoya University","subitem_publisher_language":"en"}]},"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":"0077-264X","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":"ISIKAWA, HARUZI","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"56789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKAGI, MASUMI","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"56790","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":"Vol2-2.pdf","filesize":[{"value":"3.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Vol2-2.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/19409/files/Vol2-2.pdf"},"version_id":"44fe71e6-1e00-4793-885e-8af41be9891d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"ON THE FINE STRUCTURE OF ATMOSPHERICS FROM NEAR ORIGINS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ON THE FINE STRUCTURE OF ATMOSPHERICS FROM NEAR ORIGINS","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1688"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-04-07"},"publish_date":"2015-04-07","publish_status":"0","recid":"19409","relation_version_is_last":true,"title":["ON THE FINE STRUCTURE OF ATMOSPHERICS FROM NEAR ORIGINS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-26T04:36:02.074738+00:00"}
