The two components are inherently mixed in nature, and as a result, neither process can be easily understood from a coupled atmosphere-ocean system. This has created a challenge in interpreting the observed air-sea relationships and in simulating air-sea interactions in climate models.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EHere, I will show that the ocean induced and atmospheric intrinsic variability can be cleanly dissected with targeted uncoupled atmosphere-only simulations. This uncoupled framework provides an ideal tool for developing a process-based understanding of tropical air-sea interactions and for diagnosing model biases. I will use the uncoupled framework to shed light on some important aspects of tropical convection and its interaction with the SST. I will show that convection sensitivity to SST variability is predominantly determined by the local climatological SST and that this relationship is consistent with the basic principles of moist static stability.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWebinar Link also available\u003Cbr \/\u003E\r\nhttps:\/\/global.gotomeeting.com\/join\/811813909\u003Cbr \/\u003E\r\nUnited States: +1 (646) 749-3122\u003Cbr \/\u003E\r\nAccess Code: 811-813-909\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A seminar by Dr. Jie He, School of Earth and Atmospheric Sciences "}],"uid":"35279","created_gmt":"2020-02-28 21:41:11","changed_gmt":"2020-03-02 14:56:04","author":"belnaggar3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-03-06T15:00:00-05:00","event_time_end":"2020-03-06T16:00:00-05:00","event_time_end_last":"2020-03-06T16:00:00-05:00","gmt_time_start":"2020-03-06 20:00:00","gmt_time_end":"2020-03-06 21:00:00","gmt_time_end_last":"2020-03-06 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"633149":{"id":"633149","type":"image","title":"Jie He","body":null,"created":"1582926763","gmt_created":"2020-02-28 21:52:43","changed":"1582926763","gmt_changed":"2020-02-28 21:52:43","alt":"Jie He","file":{"fid":"240914","name":"JieHe_profile.jpg","image_path":"\/sites\/default\/files\/images\/JieHe_profile.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/JieHe_profile.jpg","mime":"image\/jpeg","size":13691,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/JieHe_profile.jpg?itok=5kJKziRe"}}},"media_ids":["633149"],"groups":[{"id":"565971","name":"Ocean Science and Engineering (OSE)"}],"categories":[],"keywords":[{"id":"176779","name":"OSE Seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EEmanuele Di Lorenzo\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
