Holocene Climate Cycles in Northwest Margin of Asian Monsoon

  • Publish Date: 2012-07-05
  •  In the mid-latitude regions of the Asian continent, Zhuye Lake is located in the northwest margin of the Asian monsoon, where
    the modern climate is affected by the Asian monsoon and Westerlies. In this study, we investigated the absolutely dated Holocene
    records in Zhuye Lake for detecting the Holocene climate cycles. Totally, 14 14C dates and 6 optically simulated luminescence (OSL)
    dates are obtained from the QTH01 and QTH02 sections. The proxies of grain-size, total organic carbon content (TOC), C/N and δ13C are
    used for wavelet analysis, and the results show obvious ~256, ~512 and ~1024-year climate cycles, which are consistent with the
    Holocene millennial and centennial scale climate cycles in the typical Asian summer monsoon domain. In different parts of the Zhuye Lake,
    the Holocene sediments show variable climate cycles that are affected by the lake basin topography. In the Zhuye Lake, the Holocene
    climate cycles are mainly correlated with the solar-related Asian summer monsoon variability and the North Atlantic ice-rafting events.

Holocene Climate Cycles in Northwest Margin of Asian Monsoon

Abstract:  In the mid-latitude regions of the Asian continent, Zhuye Lake is located in the northwest margin of the Asian monsoon, where
the modern climate is affected by the Asian monsoon and Westerlies. In this study, we investigated the absolutely dated Holocene
records in Zhuye Lake for detecting the Holocene climate cycles. Totally, 14 14C dates and 6 optically simulated luminescence (OSL)
dates are obtained from the QTH01 and QTH02 sections. The proxies of grain-size, total organic carbon content (TOC), C/N and δ13C are
used for wavelet analysis, and the results show obvious ~256, ~512 and ~1024-year climate cycles, which are consistent with the
Holocene millennial and centennial scale climate cycles in the typical Asian summer monsoon domain. In different parts of the Zhuye Lake,
the Holocene sediments show variable climate cycles that are affected by the lake basin topography. In the Zhuye Lake, the Holocene
climate cycles are mainly correlated with the solar-related Asian summer monsoon variability and the North Atlantic ice-rafting events.
