This work aims at improving the theories of climate coupling within the North Pacific and across to the central tropical Pacific system and investigating their changes and response to anthropogenic forcing. Using multiple observational reanalyses and global climate model ensembles, we find that the multi-year persistence of marine heatwaves of the North Pacific is associated with the dominant modes of North Pacific decadal variability through the El Ni\u0026ntilde;o Southern Oscillation (ENSO) atmospheric teleconnections. The results suggest that the marine heatwaves in the North Pacific will be not only becoming stronger in amplitude with a larger area but also more persistent in a warming climate under anthropogenic forcing. Next, we provide observational evidence revealing that a preferred decadal timescale (~10yrs) in the Kuroshio Extension (KE) region may arise from interactions with the central tropical Pacific variability (e.g., Central Pacific ENSO, CP-ENSO). Applying satellite data with several observation reanalysis products, we suggest that the KE dynamic states can drive persistent downstream atmospheric response (e.g., wins stress curl anomalies) over the subtropical Pacific and project on atmospheric forcing of North Pacific Meridional Modes (PMM) and CP-ENSO. Finally, we diagnose the decadal KE dynamics and conclude that the decadal KE dynamics and its linkages to the tropics have not been stationary. We find that the extratropical-tropical KE coupled system has enhanced by showing a significant difference in the decadal KE statistics (e.g., timescale), especially after mid-1980. We suggest that an increase in this coupling might be associated with the stronger wind stress response of KE (e.g., atmospheric forcing of Pacific Meridional Modes) with driving the ENSO-favorable conditions. These results imply that the higher amplitude quasi-decadal fluctuations of KE\/CP-ENSO may lead to a stronger basis for decadal predictions of the Pacific region, especially for societally relevant biogeochemical quantities (e.g., salinity, oxygen, and chlorophyll-A) and fisheries.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"PACIFIC TELECONNECTIONS DYNAMICS IN A CHANGING CLIMATE: THEORIES, OBSERVATIONS, AND MODELS"}],"uid":"27707","created_gmt":"2020-08-17 18:47:04","changed_gmt":"2020-08-17 18:47:04","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-09-03T14:00:00-04:00","event_time_end":"2020-09-03T16:00:00-04:00","event_time_end_last":"2020-09-03T16:00:00-04:00","gmt_time_start":"2020-09-03 18:00:00","gmt_time_end":"2020-09-03 20:00:00","gmt_time_end_last":"2020-09-03 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
