Spatial heterogeneity in the formation of large deserts in midlatitude Asia revealed by drill core evidence

钻探揭示亚洲中部干旱区沙漠形成演化的空间异质性

Deserts are the most distinctive landscapes in the arid zones of midlatitude Asia,producing over 600 Tg of dust annually and serving as primary sources of mineral dust for the Northern Hemisphere.This dust is carried by the westerlies and the East Asian winter monsoon to downwind regions including East Asia,the northern Pacific Ocean,and even Greenland,influencing the global climate,global biogeochemical cycles,ocean productivity,Northern Hemisphere glaciations,and human health.
