Synchronous spring precipitation in Southeastern China and Bengal
Spring precipitation in southeastern China and Bengal, occurring during the transitional phase from winter to summer monsoons, serves as a critical window into the dynamics of large-scale circulations and the subsequent summer monsoon. While many studies have analyzed spring precipitation in southeastern China and Bengal, their interconnections and implications for the summer monsoon have remained relatively under explored. We utilized the Empiri…
Tree-ring recorded variations of 10 heavy metal elements over the past 168 years in southeastern China
Heavy metal pollution is a serious concern in the urban area of China. Understanding metal pollution history is crucial for setting up appropriate measures for pollution control. Herein, we report a record of concentrations of 10 heavy metals (Fe, Mn, Cu, Zn, Ni, Cr, Cd, Pb, Co, and Sr) in Pinus massoniana tree rings from Fuzhou City over the past 168 years, which represents the longest tree-ring chronology of heavy metals in China. The studied m…
Influences of West Pacific Sea Surface Temperature on Covarying Eurasian Droughts Since the Little Ice Age
The Western Pacific Warm Pool (WP), with the highest sea surface temperature (SST) in the world, has strong impacts on the drought variations in Eurasia. However, since the little ice age (1250–1850, LIA), the co-climatic drought pattern due to WP warming in Eurasia remains unclear. This is a long-term warming background for the current warming period (CWP). In this paper, we use both instrumental data and 1625 tree-ring width records from Eurasi…
Time-varying relationships among oceanic and atmospheric modes
Synchronous multi-decadal climate variability of the whole Pacific areas revealed in tree rings since 1567
Oceanic and atmospheric patterns play a crucial role in modulating climate variability from interannual to multi-decadal timescales by causing large-scale co-varying climate changes. The brevity of the existing instrumental records hinders the ability to recognize climate patterns before the industrial era, which can be alleviated using proxies. Unfortunately, proxy based reconstructions of oceanic and atmospheric modes of the past millennia ofte…
Climate of the late Pleistocene and early Holocene in coastal South China inferred from submerged wood samples
Reconstruction of soil erosion rates from exposed roots in southeast China
Southeast China, characterized by a humid subtropical climate, is dominated by dense evergreen broad-leaved forests with the exception for the Changting area, which is one of the most eroded areas in southern China. Various methods have been employed to investigate regional soil erosion dynamics, yet these studies are limited to short periods and few sites. Dendrogeomorphological methods can alleviate this problem due to the long duration of tree…
Moisture stress of a hydrological year on tree growth in the Tibetan Plateau and surroundings
Investigations of climate-growth interactions can shed light on the response of forest growth to climate change and the dendroclimatic reconstructions. However, most existing studies in the climatically important Tibetan Plateau (TP) and surrouding regions focus on linear growth responses to environmental variation. Herein we investigated both the linear and the nonlinear climate-growth interactions for 152 tree-ring chronologies in the TP and vi…
Precipitation variations and possible forcing factors on the Northeastern Tibetan Plateau during the last millennium
Understanding precipitation variation, drought and flood history, and their associated forcing mechanisms are important to human society. In this study, five moisture-sensitive tree-ring width chronologies are used to represent variations in precipitation over the past millennium on the Northeastern Tibetan Plateau (NETP). We find a strong coherency between chronologies in the NETP, indicating a common response to regional climate during the last…
Role of forest fires in Holocene stand-scale dynamics in the unmanaged taiga forest of northwestern Russia
Fossil pollen, conifer stomata, and charcoal records for the last 10,000 years were studied from three small hollow sites (Larix Hollow, Mosquito Hollow, and Olga Hollow) located at the modern western range limit of Siberian larch ( Larix sibirica) in northwestern Russia to investigate the role of forest fires in stand-scale dynamics of taiga vegetation. Wavelet coherence analysis was utilized to reveal the significance of fire on the vegetation …
Spatiotemporal drought variability for central and eastern Asia over the past seven centuries derived from tree-ring based reconstructions
Removing Biological Trends from Tree-Ring Series
The performance of the Hugershoff curve on fitting the growth trends of tree-ring series was tested using ring-width series with different starting years. The fitted values tend to be biased by tree-ring series close to pith, a phenomenon that was referred to as the “start-fitting problem”. We determined three parameters with specific biological age-related meanings for the Hugershoff growth curve, i.e. the maximum growth, the maximum slope and t…
