本文对西北太平洋地区1800 ~ 1996年7月42-52°N和140-145°E的气温进行了大尺度的树木气候重建。用树轮年表网络的主成分（PC）的多元回归模型进行重建，它解释了校准期间（1901-1996）的温度方差的31.7%。重建的空间平均7月温度表现出较大的波动，这是以前发表的树木气候重建的春季温度在东北亚。它还显示出与其他数据集的稳定关系，特别是北太平洋广大地区的海表温度（SST）和太平洋十年涛动（PDO），表明自公元1800年以来西北太平洋地区的大气-海洋相互作用。
We present a large-scale dendroclimatic reconstruction of July temperatures from 42–52°N to 140–145°E in the Northwest Pacific region for the period from 1800 to 1996. A multiple regression model with principal components (PCs) of a tree-ring chronology network was used for the reconstruction, which accounted for 31.7% of the temperature variance in the calibration period (1901–1996). The reconstructed spatially-averaged July temperatures show large fluctuations, which are comparable to previously published dendroclimatic reconstruction of spring temperatures in northeast Asia. It also shows stable relationships with other datasets, notably sea surface temperatures (SSTs) in a wide area of the North Pacific and the Pacific Decadal Oscillation (PDO), indicating atmospheric–oceanic interaction in the Northwest Pacific region since AD 1800.
