■ Abstract:
This paper will review our current understanding of the processes that determine the limits of predictability of monsoon circulation and rainfall; describe the theoretical, computational, and institutional challenges in improving models and predictions; and summarize projected changes in monsoons in the future climate. The chaotic nature of the atmosphere limits the usefulness of deterministic weather prediction of to about two weeks. However, slowly varying boundary forcings at the Earth’s surface (SST, soil wetness, snow, etc.) and their interactions with the atmosphere make it possible to predict seasonal mean circulation and rainfall.
It is well known that operational forecasts of Indian monsoon rainfall for the past 100 years have had no skill because the statistical models for IMD use too many predictors, the method of choosing the predictors gives artificial predictability, and the models produce over-confident forecasts. The lack of skill in monsoon forecasts is not due to intrinsic limits of predictability, but due to inaccurate models and insufficient observations.
This paper will show that after 50 years of climate modeling, current climate models can now produce skillful forecasts of Indian monsoon rainfall. Prediction of the space-time structure of rainfall over India remains a challenge. A strong scientific basis for the dynamical prediction of monsoon rainfall has already been established, and we now have evidence that high-fidelity climate models can produce skillful monsoon forecasts. These scientific advances should be used for the benefit of society along with improving the observing system, developing scientific capacity, and building better dynamical models to produce accurate and reliable forecasts of monsoons.
