In a remote region of the Indian Ocean lies the source of a mysterious weather pattern with tentacles that stretch across the tropics, influencing everything from monsoons in India to heat waves and flooding in the United States.

Not as well known as El Nino, this phenomenon is called the Madden-Julian Oscillation, named for Rolland Madden and Paul Julian, two scientists who discovered it in the 1970s. It starts when water vapor rises out of the Indian Ocean every 30 to 60 days to create a major ocean storm that travels west to east from near the Seychelles off Africa toward India, crosses into the tropical Pacific Ocean and eventually affects weather patterns from our West Coast to our East Coast.

This week, a team of 20 NOAA scientists are in Goa, India, to meet with 200 of India’s leading ocean, atmosphere and fisheries scientists to mark a decade of productive collaboration on ocean and atmospheric observations, with life-saving economic benefits for both nations. The most important result is the vitally important Indian Ocean observing system of buoys, the world’s key tool for early detection of monsoons, which affect the safety, food supply and economies of one third of the world’s population.

These buoys are also at the heart of detecting the Madden-Julian oscillation, providing data that NOAA depends on for U.S. weather prediction two to four weeks out.

Improving our understanding of this weather pattern is among the topics that NOAA scientists are discussing with Indian scientists on at the Second India-United States Colloquium on Earth Observations and Sciences for Society and Economy, June 11-13. Other topics include advancing tropical cyclone forecasting and understanding harmful algal blooms, which have become a serious threat to valuable Indian Ocean fisheries. NOAA is working with India on this research because there are parallels with how ocean changes in the Pacific may affect important fisheries off the U.S. West Coast.

Doordarshan, a public television station broadcast throughout India, documented the visit by Goa schoolchildren to NOAA Ship Ronald H. Brown on World Oceans Day, June 8, 2018, in Goa.

To underline the importance of the U.S. - Indian science collaboration, NOAA arranged for NOAA Ship Ronald H. Brown to arrive in Goa’s nearby port of Mormugao last week to participate in the colloquium and welcome local schoolchildren on board for a World Oceans Day tour. The ship is steaming around-the-world on a mission to improve ocean observations that underpin U.S weather and climate prediction.

At the end of the colloquium, NOAA and Indian scientists will set off on the Brown to launch three new buoys in the Indian Ocean observing system. The buoys will be moored in the Arabian Sea, an area where little data has ever been collected. Closing this data gap is expected to make the Indian Ocean observing system even more valuable to both nations and the world.

Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
