NOAA/WDS Paleoclimatology - Lake Chenghai, China 14,100 Year Lake Level Reconstruction
This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Lake Level Reconstruction. The data include parameters of lake levels|paleolimnology with a geographic location of China, Eastern Asia. The time period coverage is from 14101 to 168 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.

STUDY NOTES: Lake level reconstruction for Lake Chenghai, China for the past 14,100 years. The lake level dataset is digitalized from the original lake level curve. Please keep in mind that there are some intervals of lower uncertainty which are marked in the original curve in Fig.2
ABSTRACT SUPPLIED BY ORIGINATOR: Increasing lines of evidence question the homogenous response of Asian Summer Monsoon (ASM) precipitation patterns, requiring rethinking of the forcing mechanisms. Here we show a ~15,000-yr quantitative precipitation history based on well-dated lake levels at Lake Chenghai (LC), subtropical China. Lake levels and the inferred precipitation were high during the Bolling-Allerod, early and late Holocene, but low during the middle Holocene. The orbital scale precipitation trend is out of phase with boreal summer insolation, the later has been widely suggested as the driver of ASM precipitation. LC long term lake levels are synchronous with trends in tropical Pacific sea surface temperatures (SST), the related zonal SST gradients, and interhemispheric temperature gradients. We propose that changes in either the interhemispheric or zonal Pacific temperature gradients modulate the intensity and location of the western Pacific subtropical high, which is juxtaposed on the ASM, leading to heterogeneous hydroclimatic conditions over subtropical East Asia. |
Purpose | Records of past lake levels, mostly related to changes in moisture balance (evaporation-precipitation). Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations. |
