Roland Aloysius Madden, an American meteorologist, was a staff scientist at the National Center for Atmospheric Research (NCAR) from 1967 to 2002. His research centers on diagnostic studies of the atmosphere. Madden is a fellow of the American Meteorological Society (AMS) and a recipient of the 2002 Jule G. Charney Award of the AMS.

Biography Madden was born on May 8, 1938, in Chicago, Illinois.Ancestry.com. U.S. Public Records Index, 1950–1993, Volume 1 [database on-line].

That same year, he joined the United States Air Force where he served for four years as Duty Forecaster at Patrick Air Force Base and Assistant Staff Meteorologist at Cape Canaveral. He received his master’s and doctoral degrees in meteorology from the University of Chicago in 1967 and Colorado State University in 1978 respectively. In 1967, he was appointed staff scientist at the National Center for Atmospheric Research in Boulder Colorado where he worked for 35 years, most recently as a member of the Climate Analysis Section in the Climate and Global Dynamics Division. Madden spent periods of time as an invited scientist at a variety of institutions, including the Scripps Institute of Oceanography, Free University of Berlin, Naval Postgraduate School, Stockholm University, Max Planck Institute for Meteorology, the New Zealand National Institute of Water and Atmospheric Research, and Monash University in Melbourne, Australia. Madden retired from NCAR in 2002. He was married to Mary Agnes (née Ruh) Madden (1939–2019) for fifty-seven years, and the couple has four children.

Career highlights Over the course of his career, Madden authored over 100 research publications, technical reports, and proceedings. He is perhaps best known for his discovery in 1971 with Paul JulianMadden, R. A., and P. R. Julian, 1971: Detection of a 40–50 day oscillation in the zonal wind in the tropical Pacific. J. Atmos. Sci., 28, 702–708. of the Madden–Julian oscillation (MJO) and the comprehensive description of the phenomenon in 1972.Madden, R. A., and P. R. Julian, 1972: Description of global-scale circulation cells in the tropics with a 40–50 day period. J. Atmos. Sci., 29, 1109–1123. The MJO is an eastward moving atmospheric disturbance that traverses the planet in the tropics with a period of 30–60 days, on average. The MJO is the main intra-seasonal fluctuation explaining weather in the tropics, and it continues to be studied broadly.John E. Oliver, 2005, The Encyclopedia of World Climatology (Encyclopedia of Earth Sciences Series), Berlin:Springer, p. 476, .Chidong Zhang, 2005, "Madden-Julian Oscillation", Rev. Geophysics, 43:RG2003, 1-36.

A., 1988: Large intraseasonal variations in wind stress in the tropics. J. Geophys. Res., 93, 5330–5340. The first quantitative measures of the effects of imperfect spatial and temporal sampling on estimates of the global mean temperature;Madden, R. A., D. J. Shea, G. W. Branstator, J. J. Tribbia, and R. Weber, 1993: The effects of imperfect spatial and temporal sampling on estimates of the global mean temperature: experiments with model and satellite data. J.

Madden continues to work and publish as an NCAR Senior Scientist Emeritus. His most recent publicationMadden, R. A., 2019: How I learned to love normal-mode Rossby-Haurwitz waves. Bull. Amer. Meteor. Soc., 100, 503-511. presents new evidence of the Rossby-Haurwitz waves and appeared in 2019.
