Atmospheric circulation and drought in tropical East Asia

Based on phytolith and pollen records in a sediment core from Huguangyan Maar Lake in southern China, researchers reconstructed the history of precipitation in the lake catchment over the past 60,000 years and identified seven seasonal droughts occurring during warm interstadial periods; the authors suggest that these droughts were driven by changes in both zonal and meridional atmospheric circulations, which are therefore major determinants of hydrological changes in East Asia.
