Instrumental and modeling data suggest that extratropical storm tracks may be intensifying and shifting poleward due to anthropogenic climate change, but it is difficult to separate recent trends from natural variability because of the large amount of decadal and longer variation in storm tracks and their limited instrumental record. We reconstruct cool-season, midlatitude Pacific storm-track position and intensity from 1693 to 1995 CE using existing tree-ring chronologies along with a network of newly developed chronologies from the U.S. Pacific Northwest, where small variations in storm-track position can have a major influence on hydroclimate patterns. Our results show high interannual-to-multidecadal variability in storm-track position and intensity over the past 303 years, with spectral signatures characteristic of tropical and northern Pacific influences. Comparison with reconstructions of precipitation and tropical sea surface temperature confirms the relationship between shifting drought patterns in the Pacific Northwest and storm-track variability through time and demonstrates the long-term influence of El Niņo. These results allow us to place recent storm-track changes in the context of decadal and multidecadal fluctuations across the long-term record, showing that recent changes in storm-track intensity likely represent a warming-related increase amplified by natural decadal variability.","pubRank":"1"}],"site":[{"NOAASiteId":"57242","siteName":"North America/North Pacific","siteCode":null,"mappable":"N","locationName":"Continent>North America","geo":{"geoType":"Feature","geometry":{"type":"POLYGON","coordinates":["25","75","-150","-110"]},"properties":{"southernmostLatitude":"25","northernmostLatitude":"75","westernmostLongitude":"-150","easternmostLongitude":"-110","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"Wise2017StormTrack","NOAADataTableId":"33313","earliestYear":1693,"mostRecentYear":1995,"timeUnit":"CE","earliestYearBP":257,"mostRecentYearBP":-45,"earliestYearCE":1693,"mostRecentYearCE":1995,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/treering/reconstructions/readme-wise2017stormtrack.txt","urlDescription":"Data Description","linkText":"Reconstructed Cool-Season Storm Tracks Readme File","variables":[],"NOAAKeywords":["earth science>paleoclimate>reconstructions>atmospheric circulation"]},{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/treering/reconstructions/wise2017stormtrack.nc","urlDescription":"netCDF File","linkText":"Reconstructed Cool-Season Storm Tracks","variables":[{"cvDataType":"CLIMATE RECONSTRUCTIONS|TREE RING","cvWhat":"sampling metadata>longitude","cvMaterial":null,"cvError":null,"cvUnit":"angle unit>degree>degree east","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"CLIMATE RECONSTRUCTIONS|TREE RING","cvWhat":"earth system variable>circulation variable>circulation index>storm variable>storm track","cvMaterial":null,"cvError":"goodness-of-fit measure>root mean square error>validation root mean square error","cvUnit":"dimensionless","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"Root Mean Square Error (RMSE) between the instrumental storm track position and the CPS-predicted storm track position for each longitudinal transect.","cvFormat":"Numeric","cvShortName":null},{"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":null},{"cvDataType":"CLIMATE RECONSTRUCTIONS|TREE RING","cvWhat":"earth system variable>circulation variable>circulation index>storm variable>storm track","cvMaterial":null,"cvError":null,"cvUnit":"angle unit>degree>degree north","cvSeasonality":"6-month period>Oct-Mar","cvDetail":null,"cvMethod":"computational method>statistical analysis method>compositing method>composite plus scale","cvAdditionalInfo":"storm track latitude;
