From: Onset of frequent dust storms in northern China at ~AD 1100
Variations in dust storm events in northern China compared with global and regional conditions.
(a) Reconstructed TSI (purple line is from ref. 25 whereas pink line from ref. 26). (b) Northern Hemisphere mean temperature anomaly28. (c) Reconstructed Siberian High strength29. (d) Total population of five provinces in northwestern China (Shanxi, Gansu, Ningxia, Qinghai, Xinjiang)31. (e) Historical dust storm frequency records from northern12 and eastern13 China. (f) The 50-year averaged synthesis dust storm record across the mid-latitude Asia from Supplementary Fig. S2. (g) Percentage of >63 μm particles from Lake Gahai. Grey shading indicates the cool LIA period while orange indicates the early onset of frequent dust storms at ~AD 1100 within the warm MWP.
