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.
