We developed the first multicentury wildfire chronologies for northeast China from fire-scarred trees. Regional wildfires occurred every 7years from the 1700s to 1947, after which fire suppression policies were implemented. Regional wildfires occurred predominately during drought years and were associated with positive phases of ENSO and PDO and negative NAO. Twentieth century meteorological records show that this contingent combination of +ENSO/+PDO/-NAO is linked to low humidity, low precipitation, and high temperature during or before late spring fire seasons. Climate and wildfires in northeast China may be predictable based on teleconnection phases, although future wildfires may be more severe due to effects of climate change and the legacy of fire suppression.","author":{"name":"Qichao Yao, Peter Brown, Shirong Liu, Monique Rocca, Valerie Trouet, Ben Zheng, Haonan Chen, Yinchao Li, Duanyang Liu, and  Xiaochun Wang   "},"citation":"Qichao Yao, Peter Brown, Shirong Liu, Monique Rocca, Valerie Trouet, Ben Zheng, Haonan Chen, Yinchao Li, Duanyang Liu, and  Xiaochun Wang. 2017.
