"Long-term variability of the Afro-Asian summer monsoon and its possible causes: combined natural and anthropogenic effects"
At the same time, the warm AMO phase resulted in significant warming in the upper troposphere in North Africa and northern part of East Asia, respectively. Consequently, such warming contributed to intensification of the tropical easterly jet (TEJ) through increasing the meridional pressure gradient both in the entrance region (East Asian branch) and the exit region (African branch). The above results indicate that the Afro-Asian summer monsoon has assumed a consistent and holistic inter-decadal change.
Future projection of the Afro-Asian summer monsoon is made based on CMIP5 models with the major monsoon rainbelt located in more northern latitudes, which reflects enhanced anthropogenic effects on the Afro-Asian summer monsoon system.
