DeMenocal, P.B., and D. Rind, 1996: Sensitivity of subtropical African and Asian climate to prescribed boundary condition changes: model implications for the Plio-Pleistocene evolution of low-latitude climate. In Limnology, Climatology and Paleoclimatology of the East African Lakes. T.C. Johnson and E.O. Ouda, Eds., Taylor & Francis, pp. 57-77.

Climate model sensitivity experiments are used to assess the sensitivity of African and Asian climate to changes in solar insolarion, high-latitude glacial ice cover, North Atlantic sea surface temperatures, and South Asian orography boundary conditions. Model cli1uate responses to these boundary condition changes are discussed in tenns of their response magnitude, regional extent, and response season signatures. By region, West African climate was 1nost sensitive to cool North Atlantic SSTs which promoted annually cooler and drier surface conditions and stronger trade winds. East African/Arabian cli1nate experienced annually cooler and drier conditions due to downstream effects of high-latitude ice sheets; the region w,as very sensitive to South Asian orographic changes as well. South Asian climate was very sensitive to variations in 1nonsoon intensity resulting fro1n orbital insolation variations and changes in Tibetan/Himalayan orography. These 1nodel results stress the importance of high-latitude boundary condition changes in affecting low-latitude African and Asian climate. Plio-Pleistocene African paleoclunate can be understood in terms of the relative influences of high- and low-latitude forcing factors.
