“…A strong relationship was observed between the wavelet spectral amplitude and correlations of each two of the three influencing factors from cross-wavelet spectral analysis [9], scale-averaged wavelet power over the 2-8 year band analysis [9], and relative correlation analysis. In this study, monthly GSATA shows significant responses to SSN (mean r Jan−Dec = 0.251, p < 0.01, n = 100), and SSN also heavily influences PDO, especially in November and December.…”

“…This is most likely due to precipitation, which is a more stochastic meteorological parameter than temperature. In addition the mean sensitivity of STD (0.1775) from Zhaoingling Mausoleum, located in the city, is less than in Fuling Mausoleum, located in a suburb (0.2265) [8,9] and the Qianshan Mountains, located in natural sites (72 km to Shenyang, 0.2181) [8]. Qianshan Mountains Chinese pines and Fuling Mausoleum Chinese pines also have stronger responses to local climate than Chinese pines from Zhaoling Mausoleum [8].…”

“…Urban trees have rarely caught researcher's attention because they can be frequently disturbed by anthropogenic factors.

-A tree ring width chronology developed from 58 samples taken from Chinese pine trees (Pinus tabulaeformis Carr.) growing in Shenyang city was studied to analyze the effects of solar activity, Global Surface Air Temperature Anomalies (GSATA) and the Pacific Decadal Oscillation (PDO) on annual radial growth. An excellent response of tree rings to solar activity and global environmental change was revealed, indicating that these urban Chinese pine trees are a suitable proxy for Sun-Earth system research despite their location in Shenyang, an industrial city. The information derived from annual growth rings of urban Chinese pine trees coincides with records from undisturbed trees in a natural location, and demonstrates significant synchronous response to solar activity in the periodic bands of 5-8, 10-12 and 20-30 years. The wave signal of tree growth was also affected and amplified by the combined effect of the PDO from 1900 to 2004 and GSATA from 1880 to 2004 with a short lag time, revealing 5-8, 11-13, and 20-23 year oscillatory modes. At 20-30 year timescale, Chinese pines validated the strong GSATA influence signal at 20.8 years, and may be the primary cause of the 20 and 23 year periodic waves of tree rings. Shenyang urban tree ring growth also showed high frequency variation (2-4 y) that may be due to low periodicity of solar activity, GSATA, PDO and local climate variations, especially in the 2-4 years band width.urban tree rings / sunspot number / Pacific decadal oscillation / global surface air temperature anomaly / wavelet analysis

There is a close relationship between solar activity and the Earth's surface temperature, but this relationship has weakened with recent global warming. To better understand this puzzle, temperature records need to be extended, and the relationship between long-term variation in temperature and solar activity needs to be examined. In this study, we reconstruct April-September temperature variation back to 1563 using tree ring maximum late wood density (MXD) data from Balfour spruce in the southeastern Tibetan Plateau (TP). Spatial correlation analysis indicates that our reconstruction is representative of temperature variability over the large-scale TP. On the 22 year time scale, the reconstructed April-September temperature corresponds generally to solar activity over the past three centuries. Spectral analyses also indicate that the significant periodicities of~11 years, 54 years, and 204 years observed in the MXD chronology correspond to the Schwabe cycle, the fourth harmonic of the Suess cycle, and the Suess solar cycle, respectively. However, disparities between temperature change and solar activity are identified in two periods, the 1880s-1900s and the 1980s-present. These results suggest that solar forcing is the critical driver for long-term temperature variability in the TP, but other factors may uncouple surface temperature and solar activity in some periods. One possible cause of the weak effect of solar activity on temperature during the 1880s-1900s is internal climate variability, while human-activity-induced greenhouse gas emissions have likely superseded solar forcing as the major driver of the rapid warming observed since the 1980s.

Northeast China is one of the most vulnerable areas to climate change in high latitude regions of the Northern Hemisphere. The past temperature variations are critical to reveal the driving mechanism of climate change and to reduce the uncertainty in predicting future climates. Pre‐instrument climatic variability is poorly understood, because of the scarcity of centuries‐long climatic data. Here, we present a 211‐year (1803–2013) growing season (May–July) temperature reconstruction based on tree‐ring width chronology of Korean pine (Pinus koraiensis) from Zhangguangcai Mountains in Northeast China. The reconstruction accounted for 41.3% of the temperature variance during the calibration period from 1959 to 2013. The temperature reconstruction was similar to other nearby temperature reconstructions and correlated well spatially to gridded land and ocean surface temperature data. We identified four major cold periods (1839–1846, 1884–1901, 1906–1908 and 1941–1958) and three major warm periods (1855–1880, 1918–1932 and 1998–2013) in the past 211 years. The multi‐taper method spectral analysis revealed significant cycles at 48.8, 11.5, 8.9, 3.9, 3.5 and 2–3 years, which might be associated with global climate oscillations and land‐sea thermal contrasts, such as the sea surface temperatures, El Niño‐Southern Oscillation, Atlantic Multidecadal Oscillation and solar activity.
