Despite its importance, few studies have focused on the dynamics of hurricanes past landfall. By contrast, how hurricanes originate and grow over warm oceans has been extensively studied. Over oceans, moisture from the ocean fuels the intense winds of a hurricane heat engine. Past landfall, the hurricane is severed from this heat source, and its intensity decays. It is generally thought that this decay is a non-thermodynamic process that is dominated by the frictional drag with the land surface — crucially, moisture from the ocean plays no role in this process. Challenging this notion, we argue that the \"storm moisture\" — the stock of moisture which a hurricane carries as it strikes land — constitutes a source of heat that modulates the decay of intensity and shapes the internal structure of hurricanes past landfall. The critical, albeit unrecognized, role of storm moisture forms the leitmotif of this thesis, which consists of three parts. First, we analyze intensity data for North Atlantic landfalling hurricanes to show that the timescale of hurricane decay has increased in direct proportion to a contemporaneous rise in the sea-surface temperature over the past 50 years. Second, we show that a landfalling hurricane generates a cold-core in its eye that is distinct from the cold-core in an extratropical cyclone. Third, we show that as the cold-core grows past landfall, its competition with Ekman pumping restructures the secondary flow in the hurricane and can lead to the splitting of the hurricane. In all three cases, we show, using a blend of theory, computational simulations, and field observations, that storm moisture dictates the hurricane dynamics past landfall.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10006_dissertation_number_12":{"attribute_name":"Degree Referral Number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第66号"}]},"item_10006_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15102/1394.00001679","subitem_identifier_reg_type":"JaLC"}]},"item_10006_rights_13":{"attribute_name":"Copyright Information","attribute_value_mlt":[{"subitem_rights":"© 2020 The Author."}]},"item_10006_text_24":{"attribute_name":"Exam Date","attribute_value_mlt":[{"subitem_text_value":"2020-11-11"}]},"item_10006_version_type_18":{"attribute_name":"Version Format","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2024-11-27"}],"displaytype":"detail","filename":"320.pdf","filesize":[{"value":"53.7 MB"}],"format":"application/pdf","licensefree":"Creative Commons​\nAttribution 4.0 International​\n(https://creativecommons.org/licenses/by/4.0/","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Full_Text","objectType":"fulltext","url":"https://oist.repo.nii.ac.jp/record/1862/files/320.pdf"},"version_id":"99af9b2e-b45a-437a-ba6f-2210ef86887a"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-05"}],"displaytype":"detail","filename":"doc(1).pdf","filesize":[{"value":"42.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Final_Exam_Abstract","objectType":"abstract","url":"https://oist.repo.nii.ac.jp/record/1862/files/doc(1).pdf"},"version_id":"7f69dba3-6002-4f3e-8c5e-34302c11d3ce"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"暴風湿気と上陸ハリケーン","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"暴風湿気と上陸ハリケーン","subitem_title_language":"ja"},{"subitem_title":"Storm moisture and landfalling hurricanes","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"22","path":["200"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-01-05"},"publish_date":"2021-01-05","publish_status":"0","recid":"1862","relation_version_is_last":true,"title":["暴風湿気と上陸ハリケーン"],"weko_creator_id":"22","weko_shared_id":-1},"updated":"2023-08-31T02:52:57.058456+00:00"}
