The new monsoon mission wants to offer short-term forecasts accurate out to 15 days, and long-term seasonal forecasts that are better than the ones it issues now, based on more granular data and better computer modeling. That's a difficult computing challenge, but one that's not outside the realm of possibility. IBM's Deep Thunder project already does something like this for regions in New York, Brazil, and elsewhere. Where there is data and computing power, there is potential. India hopes to leverage that into increased economic stability for one of the world's most populous nations.
