2nd MONEX? UK, Indian Students to Board Ship to Track Monsoon

A project involving scientists from the UK and India to predict monsoon rainfall by studying ocean processes in the Bay of Bengal was launched today, Tuesday. The research team members reached Chennai and the research ship is due to set sail on June 24.

Scientists from the University of East Anglia (UEA) will release underwater robots to monitor how ocean conditions influence monsoon rainfall. Meanwhile, collaborators from a partner project led by the University of Reading with collaborators across the UK and India will use a state-of-the-art aircraft to take atmospheric measurements at the same time.

It is hoped that the combined results of this large-scale scientific campaign will help forecast the arrival of the Indian monsoon more accurately than ever before. “Similar project was undertaken in 1972 and experiments were carried out “MONEX” (monsoon experiments) by SAC-ISRO using Dakota aircraft and collected sea temperature data,” said Naresh Shukla, a member of the MONEX team.

The aim of any mission is to predict rainfall accurately so that it leads to subsistence farming, improve the livelihoods of millions of people, and help mitigate the damage caused by monsoons when they hit land.

Summer monsoons provide 80 per cent of annual rainfall to around a billion people in India.Forecasting the precise timing and location of the rains is vital to the region’s economy, which is dominated by farming, and for managing its increasingly pressured water resources.

Accurate predictions of intense downpours and breaks in the monsoon are essential to help farmers plan their crop planting and communities prepare for floods and droughts.

Last year, the monsoon spread rapidly over northern India, causing devastating damage, whereas prolonged breaks in 2009 led to a severe shortage of rainfall and poor harvests.

The Indian Met Department has been using supercomputers to provide a forecast as a whole, dividing the country into five regions. The forecast has not been entirely useful though it employs historical records and also uses six to eight predicting factors in its analysis.

Lead researcher Prof Adrian Matthews, from UEA’s School of Environmental Sciences, said: “The Indian monsoon is notoriously hard to predict. It is a very complicated weather system and the processes are not understood or recorded in science. We will be combining oceanic and atmospheric measurements to monitor weather systems as they are generated. Nobody has ever made observations on this scale during the monsoon season itself so this is a truly ground-breaking project.”

The Bay of Bengal Boundary Layer Experiment (BoBBLE) is led by UEA scientists in collaboration with the University of Reading and the National Oceanography Centre (NOC) in Southampton.

Collaborators in India include the Centre for Atmospheric and Oceanic Sciences (CAOS), the Indian National Centre for Climate Information Services (INCOIS), the National Centre for Medium Range Weather Forecasting (NCMRWF) and the National Institute of Ocean Technology (NIOT).

The UEA team will arrive in India today and are due to set sail on June 24 from Chennai into the Bay of Bengal on the Indian research ship the Sindhu Sadhana. Dr M Rajeevan, secretary for the Indian Ministry of Earth Sciences, will visit the ship and meet the research team on the afternoon of its departure.

Once out in the ocean, they will then release seven underwater gliders to measure ocean properties such as temperature, salinity and current.

The team will spend a month at sea – with data from the 250-mile stretch of international water beamed back to the UK using mobile phone signals daily.

Back in the UK, researchers at UEA, the University of Reading and NOC, will use this data to create computer models of the ocean to determine how it affects weather systems and rainfall over India.

“Our collaborators will be flying out from Bangalore to make simultaneous observations in the atmosphere above us. It will be really rather spectacular,” added Prof Matthews.

Previous missions undertaken by UEA’s fleet of gliders have helped researchers make a variety of discoveries including why the Antarctic ice caps are melting.

The project is funded by the Natural Environment Research Council, the Newton Fund, the Indian Ministry of Earth Sciences (MoES) and the UK’s Met Office.

  1. In 1972 similar type of experiments was carried out “MONEX” (monsoon experiments) by SAC-ISRO using Dakota aircraft and collected sea temperature data I was member of this team
