The Cabinet Committee on Economic Affairs
approved the implementation of the programme of the National Monsoon
Mission at the Earth System Science Organisation (ESSO) for a period of
five years.
The main objectives of the National Monsoon Mission are:
(i) To build a working partnership between the academic and R&D
organisations both national and international and the operational
agencies to improve the operational monsoon forecast skill over the
country.
(ii) To set up a state of the art dynamic modelling framework for improving the prediction skill of:
a. Seasonal and extended range prediction system (16 days to one season)
b. Short to medium range prediction system (up to 15 days).
The Mission has a budget of Rs.400 crore for five years to support the research work related to the mission.
The National Monsoon Mission after its implementation will help to
implement a dynamic prediction system for the prediction of monsoon in
all time scales, short range to seasonal time scale at appropriate
spatial scales with improved prediction skill. The forecasts based on
this prediction system will cater to the needs of various sectors like
agriculture, water resources management, power generation, disaster
management, tourism and transport.
The programme will be undertaken through two sub-missions on two
different time scales, (i) extended range to seasonal time scale to be
coordinated by the Indian Institute of Tropical Meteorology (IITM)
Pune/ESSO and (ii) short to medium range scale, to be coordinated by the
National Centre for Medium Range Weather Forecasting (NCMRWF)/ESSO.
The Indian National Center for Ocean Information Services (INCOIS)/ESSO
will provide the ocean observations for assimilation and the India
Meteorological Department/ESSO will implement the research outcome of
the efforts in operational mode. The Mission will support focused
research by national and international research groups with definitive
objectives and deliverables to improve the models in the short, medium,
extended and seasonal range scales at appropriate spatial scales. The
Mission will also support observational programmes that will result in
better understanding of the processes. The progress of the National
Monsoon Mission will be reviewed and monitored by two committees. The
Scientific Review and Monitoring Committee (SRMC) will review the
research proposals from different research groups and monitor the
progress of the research work. The Scientific Steering Committee (SSC),
which is the apex body will steer the programme, advise and direct
midcourse corrections, if any.
Background:
Prediction of monsoon rainfall variability in all spatial and time
scales is very important for many sectors like agriculture, water
resources management, power generation and natural ecosystems and thus
economy of the country. The present statistical methods being used by
the India Meteorological Department have some constraints to meet
specific user requirements for forecasts on finer spatial and temporal
scale. Therefore, it is necessary to make use of the state of the art
dynamic models to improve monsoon prediction skills.
