利用冰芯、年轮和历史文献等不同的古气候资料，分析了中国北方近1000年沙尘暴事件及其与气候变化的关系。结果表明：在半干旱区，气温和降水序列与沙尘暴频率在年代际尺度上呈显著负相关；然而，与温度变化相比，在百年时间尺度上，降水变化与沙尘暴事件之间存在更密切的相关性。在这个时间尺度上，降水占过去1700年降尘变化变化的40%，推断降水对沙尘暴形成的控制。在西部干旱区，气温和降水变化都是该地区百年尺度沙尘暴发生的重要强迫因子。东部干旱区沙尘暴事件与气候变化的关系与半干旱区相似。因此，气候变化对沙尘暴事件的影响在过去一千年的十年和百年时间尺度上表现出来。然而，气候变化与沙尘暴频率之间的关系存在相移。对1400年西伯利亚高压强度的重建表明，春季西伯利亚高压强度的长期变化可能为中国北方历史沙尘暴事件发生频率的动力条件提供了背景。
Dust storm events and their relation to climate changes in Northern China during the past 1000 years were analyzed by using different paleoclimate archives such as ice cores, tree rings, and historical documents. The results show that in the semiarid region, the temperature and precipitation series were significantly negatively correlated to the dust storm frequency on a decadal timescale. Compared with temperature changes, however, there was a closer correlation between precipitation changes and dust storm events on a centennial timescale. At this timescale, precipitation accounts for 40% of the variance of dust fall variations during the last 1700 years, inferring precipitation control on the formation of dust storms. In the western arid region, both temperature and precipitation changes are important forcing factors for the occurrence of dust storms in the region on a centennial timescale. In the eastern arid region, the relationship between dust storm events and climate changes are similar like in the semiarid region. As a result, the effects of climate change on dust storm events were manifested on decadal and centennial timescales during the last millennium. However, there is a phase shift in the relation between climate change and the dust storm frequency. A 1400 years reconstruction of the strength of the Siberian High reveals that long-term variations of spring Siberian High intensity might provide a background for the dynamic conditions for the frequency of historical dust storm events in Northern China.
