Positive PNA phases in our record are associated with warm phases of ENSO and PDO and the reorganization of the PNA pattern towards a positive mode is strongest when ENSO and PDO are in phase. Regime shifts in our PNA record correspond to climatic shifts in other proxies of Pacific climate variability, including two well-documented shifts in the instrumental period (1976 and 1923). The correspondence breaks down in the early 19th century, when our record shows a prolonged period of positive PNA, with a peak in 18001820. This period corresponds to a period of low solar activity (Dalton Minimum), suggesting a positive PNA like response to decreased solar irradiance. The distinct 30-year periodicity that dominates the PNA reconstruction in the 18th century and again from 1875 onwards is disrupted during this period.","pubRank":"1"}],"site":[{"NOAASiteId":"15765","siteName":"Mount Everts","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Wyoming","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["44.98","-110.67"]},"properties":{"southernmostLatitude":"44.98","northernmostLatitude":"44.98","westernmostLongitude":"-110.67","easternmostLongitude":"-110.67","minElevationMeters":"2179","maxElevationMeters":"2179"}},"paleoData":[{"dataTableName":"PNA_trouet2009","NOAADataTableId":"38686","earliestYear":1725,"mostRecentYear":1999,"timeUnit":"CE","earliestYearBP":225,"mostRecentYearBP":-49,"earliestYearCE":1725,"mostRecentYearCE":1999,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/treering/reconstructions/pna-trouet2009-noaa.txt","urlDescription":"NOAA Template File","linkText":"Winter Pacific North American Reconstruction Data","variables":[{"cvDataType":"CLIMATE RECONSTRUCTIONS|TREE RING","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"age"},{"cvDataType":"CLIMATE RECONSTRUCTIONS|TREE RING","cvWhat":"earth system variable>circulation variable>circulation index>Pacific-North American Pattern","cvMaterial":null,"cvError":null,"cvUnit":"dimensionless","cvSeasonality":"non-calendric period>winter","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"pna"}],"NOAAKeywords":["earth science>paleoclimate>reconstructions"]}]}]},{"NOAASiteId":"16128","siteName":"North Fork Ridge","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Montana","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["45.3","-111.33"]},"properties":{"southernmostLatitude":"45.3","northernmostLatitude":"45.3","westernmostLongitude":"-111.33","easternmostLongitude":"-111.33","minElevationMeters":"2500","maxElevationMeters":"2500"}},"paleoData":[{"dataTableName":"PNA_trouet2009","NOAADataTableId":"38686","earliestYear":1725,"mostRecentYear":1999,"timeUnit":"CE","earliestYearBP":225,"mostRecentYearBP":-49,"earliestYearCE":1725,"mostRecentYearCE":1999,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/treering/reconstructions/pna-trouet2009-noaa.txt","urlDescription":"NOAA Template File","linkText":"Winter Pacific North American Reconstruction Data","variables":[],"NOAAKeywords":["earth science>paleoclimate>reconstructions"]}]}]},{"NOAASiteId":"17564","siteName":"Fish Trap","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Alaska","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["60.48","-154.33"]},"properties":{"southernmostLatitude":"60.48","northernmostLatitude":"60.48","westernmostLongitude":"-154.33","easternmostLongitude":"-154.33","minElevationMeters":"550","maxElevationMeters":"550"}},"paleoData":[{"dataTableName":"PNA_trouet2009","NOAADataTableId":"38686","earliestYear":1725,"mostRecentYear":1999,"timeUnit":"CE","earliestYearBP":225,"mostRecentYearBP":-49,"earliestYearCE":1725,"mostRecentYearCE":1999,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/treering/reconstructions/pna-trouet2009-noaa.txt","urlDescription":"NOAA Template File","linkText":"Winter Pacific North American Reconstruction Data","variables":[],"NOAAKeywords":["earth science>paleoclimate>reconstructions"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
