For the AGWs in 557.7\u2010nm images, the power spectra in summer are stronger than in other seasons, probably due to stronger tropospheric convection. The highest energy content of the waves are mostly at wavelengths between 20 and 300 km at MGD, ATH, and RIK, while it is above 200 km at SGK. The largest power spectral density is obtained at RIK at wavelengths of 30\u2013100 km and then ATH. The slopes of the horizontal wavenumber spectra varies from \u22122.77 to \u22123.22. From the MSTIDs in 630.0\u2010nm images, the power spectra in summer at RIK and SGK are stronger than those in other seasons regardless of solar activity. The power spectra in solar quiet time are stronger than those in solar active time at all four stations. These features can be explained by the Perkins instability with coupling between sporadic E and F layers. The spectral slope decreases with increasing latitudes. Weak positive correlations were obtained between the daily wave power of AGWs in 557.7\u2010nm images and MSTIDs in 630.0\u2010nm images, suggesting that the MSTIDs in the thermosphere may be partially generated by the AGWs from the mesopause region.", "subitem_description_type": "Abstract"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Wiley"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1029/2019JA026807", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2020 American Geophysical Union"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_61": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "2169-9380", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tsuchiya, Satoshi"}], "nameIdentifiers": [{"nameIdentifier": "101163", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shiokawa, Kazuo"}], "nameIdentifiers": [{"nameIdentifier": "101164", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Otsuka, Yuichi"}], "nameIdentifiers": [{"nameIdentifier": "101165", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Takuji"}], "nameIdentifiers": [{"nameIdentifier": "101166", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamamoto, Mamoru"}], "nameIdentifiers": [{"nameIdentifier": "101167", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Connors, Martin"}], "nameIdentifiers": [{"nameIdentifier": "101168", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Schofield, Ian"}], "nameIdentifiers": [{"nameIdentifier": "101169", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shevtsov, Boris"}], "nameIdentifiers": [{"nameIdentifier": "101170", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Poddelsky, Igor"}], "nameIdentifiers": [{"nameIdentifier": "101171", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-09-14"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2019JA026807.pdf", "filesize": [{"value": "3.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3700000.0, "url": {"label": "2019JA026807", "url": "https://nagoya.repo.nii.ac.jp/record/30433/files/2019JA026807.pdf"}, "version_id": "d8e51c09-495f-44e8-9435-1f292c2384df"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Wavenumber Spectra of Atmospheric Gravity Waves and Medium\u2010Scale Traveling Ionospheric Disturbances Based on More Than 10\u2010Year Airglow Images in Japan, Russia, and Canada", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Wavenumber Spectra of Atmospheric Gravity Waves and Medium\u2010Scale Traveling Ionospheric Disturbances Based on More Than 10\u2010Year Airglow Images in Japan, Russia, and Canada"}]}, "item_type_id": "10", "owner": "1", "path": ["879/880/881"], "permalink_uri": "http://hdl.handle.net/2237/00032618", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2020-09-14"}, "publish_date": "2020-09-14", "publish_status": "0", "recid": "30433", "relation": {}, "relation_version_is_last": true, "title": ["Wavenumber Spectra of Atmospheric Gravity Waves and Medium\u2010Scale Traveling Ionospheric Disturbances Based on More Than 10\u2010Year Airglow Images in Japan, Russia, and Canada"], "weko_shared_id": null}
