The Union Ministry of Earth Sciences (MoES) in the last week of July 2016 announced that India Meteorological Department (IMD) will use supercomputer to forecast India’s annual summer monsoon.
•    The forecast made by a supercomputer will be based on a dynamical monsoon model. It will be operational from 2017.
•    The dynamical model is also known as the Coupled Forecast System.
•    It collates data on local as well as global weather patterns to simulate a forecast for a specific duration.
•    The Indian Institute of Tropical Meteorology (IITM), Pune, has been using this model on an experimental basis for around 10 years to assist IMD’s annual monsoon forecasts.
•    To operationalise the alternate model, IMD is investing in supercomputers that can function at a speed of 10 petaflops-per second system.
•    The dynamical model has achieved a 60% accuracy at present and IMD aims to take it up to 77%.
•    The dynamical model and faster computing will also improve short range forecasts as the IMD will be able to access sharper resolution images.
