Cosmogenic ¹⁰Be is a promising precipitation index, because its fallout flux in sediments is mainly controlled by wet precipitation after its production in the atmosphere.  

     Based on the high precision measurement of ¹⁰Be and the study of various climate proxies, the last 130 ka paleoprecipitation from  Chinese loess ¹⁰Be was reconstructed. The general variation of the new ¹⁰Be precipitation record compares well with δ¹⁸O records from Hulu-Sanbao caves, which is widely regarded as a reliable record of Asian Monsoon intensity. Like speleothem δ¹⁸O, the ¹⁰Be precipitation record from loess during MIS 5 clearly reveals sub-cycles (MIS 5a-MIS 5e) of precipitation changes. The variation trend of our ¹⁰Be-derived precipitation record is broadly consistent with summer (June, July, and August, (JJA)) solar insolation changes in the Northern Hemisphere, except during MIS 3, supporting the idea that paleo-Asian Monsoon intensity varies directly with changes in Northern Hemisphere summer insolation on orbital timescales.The precipitation record more strongly resembles the insolation differential between 30°N and 30°S during MIS 3, suggesting that the paleoprecipitation increase during MIS 3 in China appears to be controlled by interhemispheric insolation forcing, in response to the interaction between the Northern and Southern Hemispheres.
