| 1 | Possible solar forcing of climate variability in the past 4000 years inferred from a proxy record at the southern margin of Tarim Basin显示文摘A ca. 4000a decadal-resolution climate proxy record of the mean grain-size from a lake (or mash) sediment at the southern margin of the Tarim Basin, correlates visu- ally with the atmospheric △14C, record from tree ring (residual △14C, solar proxy)and the GISP2 ice core 8O record (tem- peralure proxy). In general, △14 C maxima (solar minima) are coincident With cold (wet) periods in the study area and cold periods in the (;reenland ice core. Power spectrum analysis revealed statislically significant periodicities of 196a, 121a, 97a, 62a, 45a and 33—30a, which are similar to those prin- cipal solar-oscillation periods as inferred from the atmos- pheric radiocarbon and other proxy records. Possible solar forcing is addressed to be the main driving forcing of climate change in the southern margin of Tarim Basin. | ZHONGWei WANGLiguo Tyip·Tashpolat XIONGHeigang SHUQiang | 2004 | Chinese Science Bulletin2004，49，11： | 9 |
