The Pune-based institute requires higher supercomputing power as it deals with seasonal weather forecasts while the NCMRWF deals with medium-range forecasts for a period extending three to seven days in advance.

The new high-power computing facility is expected to improve weather forecasts at the block level, help weather scientists give higher resolution ranges of the forecast, predict cyclones with more accuracy and lead time, and ocean state forecasts, including marine water quality forecasts.

"Presently, we give forecasts with a 12-kilometer resolution. The new supercomputer will improve it to six-kilometer resolution. We aim to achieve one-kilometer resolution forecasts," Ministry of Earth Sciences Secretary M Ravichandran said.
