摘要

Abundant geological climatic records indicate that northern Tibetan Plateau and southern-eastern Africa have uplifted significantly since Pliocene, at the same time, the Asian summer monsoon climate has undergone great changes. The connection between them is a hot scientific topic in the earth science field. In this paper we conduct a modeling study to explore the climatic effects of tectonic uplifts in northern Tibetan Plateau and southern-eastern Africa since Pliocene by using the Community Atmosphere Model (CAM3.1) of National Center for Atmospheric Research (NCAR). The results show that the intensification of Asian summer monsoon since Pliocene has close but differential relationships with the tectonic uplifts in the two regions during this period. The uplift of northern Tibetan Plateau mainly intensifies the summer monsoon and increases the precipitation over northern East Asia,and has less effect on South Asian summer monsoon. Whereas, the uplift of southern-eastern Africa principally strengthens South Asian summer monsoon but has less influence on northern East Asian summer monsoon.
