来自阿曼南部的一颗钍铀定年石笋的高分辨率氧同位素记录反映了距今（ky B.P.）之前10.3至2.7万年和1.4至0.4万年的季风降水量的变化。在10.3 ~ 8 ky b.p.之间，季风降水的年代际至百年变化与格陵兰冰芯记录的温度波动相一致，表明全新世早期季风强度主要受冰川边界条件控制。在类似于8天b.p.之后，季风降水随着北半球夏季太阳日照的变化而逐渐减少，季风降水的年代际到多年代际变化与太阳活动有关。
A high-resolution oxygen-isotope record from a thorium-uranium-dated stalagmite from southern Oman re. ects variations in the amount of monsoon precipitation for the periods from 10.3 to 2.7 and 1.4 to 0.4 thousand years before the present (ky B.P.). Between 10.3 and 8 ky B. P., decadal to centennial variations in monsoon precipitation are in phase with temperature fluctuations recorded in Greenland ice cores, indicating that early Holocene monsoon intensity is largely controlled by glacial boundary conditions. After similar to8 ky B. P., monsoon precipitation decreases gradually in response to changing Northern Hemisphere summer solar insolation, with decadal to multidecadal variations in monsoon precipitation being linked to solar activity.
