Ice volume and insolation forcing of abrupt strengthening of East Asian winter monsoon during glacial inceptions
It is generally accepted that the glacial-interglacial variations of the East Asian winter monsoon (EAWM) are controlled by the volume of the Northern Hemisphere ice sheets (NHIS), but the fact that they exhibit different evolution patterns during glacial inceptions is often overlooked.

It is generally accepted that the glacial-interglacial variations of the East Asian winter monsoon (EAWM) are controlled by the volume of the Northern Hemisphere ice sheets (NHIS), but the fact that they exhibit different evolution patterns during glacial inceptions is often overlooked.

This climate teleconnection between North Atlantic and East Asia is found to be particularly effective only when the NHIS reaches a critical large size.
