Rainfall and other forms of Precipitation

 A model of the coupled ocean–atmosphere system, the climate forecast system (CFS), from the National Centre for Environmental Prediction (NCEP), USA, has been ported onto the PARAM Padma parallel computing system at the Centre for Development of Advanced Computing (CDAC), Bangalore and retrospective predictions for the summer monsoon (June–September) season of 2009 have been generated, using five initial conditions for the atmosphere and one initial condition for the ocean for May 2009.
