Pan-Asian monsoon water isotope variability is found accompanied by a continental-scale hydroclimate footprint.
Abstract The Tibetan Plateau (TP) has an average elevation of over 4000 m and with its surrounding mountains is regarded as Earth’s “third pole.” As a result size height, climate change in the TP own unique characteristics that include proposed positive correlation between surface temperature pressure. This study examines trends relationships pressure through examination monthly mean data from 71 stations during 1961–2013. On annual, seasonal, time scales, exhibits statistically significant...
Abstract The persistent discrepancy between climate models and proxy records regarding temperature variations throughout the Holocene remains evident in our latest isotope‐enabled transient simulations (iTRACE). This study quantifies model sensitivity to insolation forcing investigates origins of uncertainties mid‐Holocene temperatures by combining iTRACE with multi‐model from Palaeoclimate Model Intercomparison Project (PMIP4) component phase Coupled (CMIP6). We show that inter‐model...
Very high tropical alpine ice cores provide a distinct paleoclimate record for climate changes in the middle and upper troposphere. However, climatic interpretation of key proxy, stable water oxygen isotopic ratio (δ 18 O ), remains an outstanding problem. Here, combining proxy records with models, modern satellite measurements, radiative-convective equilibrium theory, we show that δ is indicator temperature troposphere, glacial cooling −7.35° ± 1.1°C (66% CI). Moreover, it severs as...
Abstract Oxygen isotope speleothems have been widely used to infer past climate changes over tropical South America (TSA). However, the spatial patterns of millennial precipitation and δ 18 O ( p ) response remained controversial, their mechanisms are unclear. In particular, it is not clear whether regional represents intensity American summer monsoon (SASM). Here, we study TSA hydroclimate variability during last deglaciation (20–11 ka ago) by combining transient simulations an...
Abstract Understanding the hydroclimate representations of precipitation δ 18 O ( p ) in tropical South America (TSA) is crucial for climate reconstruction from available speleothem caves. Our preceding study (Part I) highlights a heterogeneous response millennial over TSA during last deglaciation (20–11 ka before present), characterized by northwest–southeast (NW–SE) dipole both rainfall and , with opposite signs between central-western Amazon eastern Brazil. Mechanisms such are further...
