An international team of researchers begins gathering in the Indian Ocean in October 2011 to study an atmospheric pattern that affects weather worldwide. The six-month field campaign, known as DYNAMO (Dynamics of the Madden-Julian Oscillation), will help improve long-range weather forecasts and seasonal outlooks, and enable scientists to further refine computer models of global climate. The MJO was first recognized as an important weather-maker pattern by NCAR scientists Roland Madden and Paul Julian in the 1970s.

video icon Tropical weather maker in motion. The Madden-Julian Oscillation is a cyclical disturbance of the tropical atmosphere with pulses that typically originate in the Indian Ocean every 30 to 60 days and travel eastward. During each pulse of the MJO, regional westerly winds replace easterly trade winds near the surface, and showers and thunderstorms increase, particularly over regions of high sea surface temperatures in the Indian and western Pacific oceans.
