WP 2000

We have continued with the investigation of the possible climatic changes affecting the Indian summer monsoon due to the greenhouse warming on the basis of our time-slice experiment with the ECHAM4 AGCM. We have, a.o., extended our work to extreme precipitation events and the monsoon-ENSO relationship. Further, we have looked at a AMIP-type simulation with ECHAM4 and compared it to ERA data for the corresponding period. This is done in order to get a better understanding of the model’s ability to simulate the Indian summer monsoon properly as well as of the role of possible systematic errors of the SSTs, considering both the mean state and the sub-seasonal variability.
