(THE GIST OF PIB) National Monsoon Mission

[February-2021]

National Monsoon Mission

  • National Monsoon Mission (NMM) under the Ministry of Earth Science was launched in 2012 to develop a state-of-the-art dynamical prediction system for monsoon rainfall.
  • Prediction models include models for short to medium range (1-10 days), extended-range (10 days to 30 days) and seasonal.

Other targets of NMM are:

  • Developing partnership between Indian and foreign institutes to develop a system for prediction of extremes.
  • Develop a system for climate applications having social impacts (such as agriculture, flood forecast etc.)
  • NMM augmentation with High-performance Computing facilities has helped in achieving a paradigm shift in weather and climate modeling for operational weather forecasts.
  • Indian Institute of Tropical Meteorology, Pune is responsible for execution and coordination of mission.
  • Major achievements of NMM during the last three years (phase 2) are:
  • Monsoon Mission dynamical model to prepare operational seasonal forecast of monsoon rainfall.
  • Improvement in cyclone tracking and intensity prediction.
  • Commissioning of a Global Ensemble Forecast System for short and medium range prediction.

  • Minister of Earth Science informed Rajya Sabha about National Monsoon Mission.

About:

  • Under the Monsoon Mission, Ministry has developed the state-of-the-art weather and climate prediction models, which are now in operational use.
  • These models include models for short-range to medium range (1-10 days), extended range (10days to 30 days) and seasonal (up to one season).

Following are the targets of Monsoon Mission:

  • Development of a seamless prediction system using monsoon mission model, on different time scales, like Seasonal (for whole Monsoon season), Extended range (up-to 4 weeks), Short range prediction (up-to 5days).
  • Initiate and coordinate working partnerships between Indian and foreign institutes to develop a system for prediction of extremes and climate applications.
  • Develop and implement system for climate applications having social impacts (such as agriculture, flood forecast, extreme events forecast, wind energy, etc.).
  • Advanced data assimilation system for preparing high quality data for model predictions.

Major achievements of NMM during the last three years are:

  • Setting up of an advanced prediction system for Seasonal prediction; Extended range prediction and Very high-resolution Short-range prediction.
  • Commissioning of a Global Ensemble Forecast System (GEFS) for short and medium-range prediction at 12km.
