(1) IBM GRAF, as the forecast system is called, can generate forecasts at a resolution of 3 kilometres.
(2) This is a significantly higher resolution than the 12-kilometre models used by the India Meteorological Department to generate forecasts.
(3) These weather forecast techniques rely on dynamic modelling and collect a trove of atmospheric and ocean data, crunch it in supercomputers and generate forecasts over desired time-frames — three days, weekly or fortnightly.
- IBM data collection and forecasting: For its forecasts, IBM relies on a global network of sensors — automatic weather station, data bouys and barometric pressure data from cellphones of users who’ve downloaded the application.
- Effect of climate change on economy: A study by IBM found that 72% Indians believed that the local economy had been disrupted by a severe weather event in the past year and 89% were concerned that climate change could negatively impact the economy
