We thank Prof. B. N. Goswami, Director, IITM, for the valuable discussions and the support. We are grateful to the two anonymous reviewers and to editor Prof. Bin Wang for the thought-provoking comments that helped in improving the manuscript. We acknowledge Dr. Sahai and Mrs. Sujata Mandke for making available to us rainfall output from the PUM simulation. This work was funded by the INDOMOD (ISP-1.5) project. The 20-year AGCM run was conducted using a Cray-T932 supercomputer at NIED, Tsukuba, when RK was a visiting researcher at FRSGC, Japan.
