The Asian summer monsoon
response to global warming was investigated by a transient greenhouse
warming integration with the ECHAM4/OPYC3 CGCM (Hu et al. 2000).
It has been demonstrated that increases of greenhouse
gas concentrations intensify
the Asian summer monsoon and its variability. The intensified monsoon
results mainly from an enhanced land-sea contrast and a northward
shift of the covergence zone. A gradual increase of the monsoon
variability was simulated from year 2030 onwards. It seems
to be connected with the corresponding increase of the sea surface temperature
variability over the tropical Pacific.
The results will be published
in the Geophysical Research Letters.
