Long-lead predictability of Indian summer monsoon rainfall from the new upgraded version of the monsoon mission coupled forecast system (MMCFSv2)
The study demonstrates that the upgraded Monsoon Mission Climate Forecast System version 2 (MMCFSv2) achieves its highest long-lead predictability for Indian Summer Monsoon rainfall when initialized in April, significantly improving the simulation of rainfall phase, amplitude, and extreme years compared to other initialization times.
