Are there different modes of the Asian Monsoon?
Abstract
It is well known that the global climate system can exist in different modes, such as the Greenhouse/Icehouse and Glacial/Interglacial mode. The glacial and interglacial mode are best understood and characterized, among others, by distinct oceanic circulation patterns. The transition between different modes can be very rapid (<100a) reflecting non-linear phase-transitions. Here we analyze monsoonal patterns of the Third Pole region over the last 9 ma to identify if there exist distinct modes of Asian monsoon and if the monsoonal patterns of the Neogene Greenhouse differs from the Pleistocene/Holocene Icehouse. Thereby we consider previously published data as well as own palynological data from the Zhada Basin and NamCo area on the Tibetan Plateau as well as various modeling studies.
