| Evidence and modeling study of droughts in China during 4―2 ka BP |
| |
| 摘 要： | Four periods with predominated droughts are identified in 4-2 ka BP according to documentary data, namely 3.6-3.5, 3.1-3.0, 2.8-2.7, and 2.45-2.35 ka BP. Palaeo-environmental data indicated that droughts were predominated in 4-2 ka BP in the south of Northeast China, Inner-Mongolia, east of Qinghai-Tibetan Plateau, and South China. Modeling study shows that precession may be responsible for the occurrence of droughts in 4-2 ka BP, integrating the GCM with forcing of insolation.

| Abstract: | Four periods with predominated droughts are identified in 4-2 ka BP according to documentary data, namely 3.6–3.5, 3.1–3.0,
2.8–2.7, and 2.45–2.35 ka BP. Palaeo-environmental data indicated that droughts were predominated in 4-2 ka BP in the south
of Northeast China, Inner-Mongolia, east of Qinghai-Tibetan Plateau, and South China. Modeling study shows that precession
may be responsible for the occurrence of droughts in 4-2 ka BP, integrating the GCM with forcing of insolation.
