Roland Aloysius Madden, an American meteorologist, was a staff scientist at the National Center for Atmospheric Research (NCAR) from 1967 to 2002. [5] [6] His research centers on diagnostic studies of the atmosphere. Madden is a fellow of the American Meteorological Society (AMS) [7] and a recipient of the 2002 Jule G. Charney Award of the AMS.
Madden was born on May 8, 1938, in Chicago, Illinois. [8] [9] He grew up in Edison Park in northwest Chicago and attended St. Juliana’s Grammar School and Fenwick High School [10] He received his Bachelor of Science degree in physics from Loyola University Chicago in 1961. [8] [2] 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. [8] [5] [2] He received his master’s and doctoral degrees in meteorology from the University of Chicago in 1967 [2] and Colorado State University in 1978 respectively. [4] In 1967, he was appointed staff scientist at the National Center for Atmospheric Research in Boulder Colorado where he worked for 35 years, [5] 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, University of Stockholm, 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. [5] He was married to Mary Agnes (née Ruh) Madden (1939–2019) for fifty-seven years, and the couple has four children. [11]
Over the course of his career, Madden authored over 100 research publications, technical reports, and proceedings. [3] He is perhaps best known for his discovery in 1971 with Paul Julian [pub 1] of the Madden–Julian oscillation (MJO) and the comprehensive description of the phenomenon in 1972. [8] [pub 2] 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. [12] [13]
Selected areas of important contributions (and related publications) in addition to the MJO [3] include:
Madden continues to work and publish as an NCAR Senior Scientist Emeritus. [14] His most recent publication [pub 12] presents new evidence of the Rossby-Haurwitz waves and appeared in 2019.
Richard Siegmund Lindzen is an American atmospheric physicist known for his work in the dynamics of the middle atmosphere, atmospheric tides, and ozone photochemistry. He is the author of more than 200 scientific papers. From 1972 to 1982, he served as the Gordon McKay Professor of Dynamic Meteorology at Harvard University. In 1983, he was appointed as the Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology, where he would remain until his retirement in 2013. Lindzen has disputed the scientific consensus on climate change and criticizes what he has called "climate alarmism".
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El Niño and the cooling phase as La Niña. The Southern Oscillation is the accompanying atmospheric component, coupled with the sea temperature change: El Niño is accompanied by high air surface pressure in the tropical western Pacific and La Niña with low air surface pressure there. The two periods last several months each and typically occur every few years with varying intensity per period.
The University Corporation for Atmospheric Research (UCAR) is a US nonprofit consortium of more than 100 colleges and universities providing research and training in the atmospheric and related sciences. UCAR manages the National Center for Atmospheric Research (NCAR) and provides additional services to strengthen and support research and education through its community programs. Its headquarters, in Boulder, Colorado, include NCAR's Mesa Laboratory, designed by I.M. Pei.
The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal variability in the tropical atmosphere. It was discovered in 1971 by Roland Madden and Paul Julian of the American National Center for Atmospheric Research (NCAR). It is a large-scale coupling between atmospheric circulation and tropical deep atmospheric convection. Unlike a standing pattern like the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation is a traveling pattern that propagates eastward, at approximately 4 to 8 m/s, through the atmosphere above the warm parts of the Indian and Pacific oceans. This overall circulation pattern manifests itself most clearly as anomalous rainfall.
The US National Center for Atmospheric Research is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF). NCAR has multiple facilities, including the I. M. Pei-designed Mesa Laboratory headquarters in Boulder, Colorado. Studies include meteorology, climate science, atmospheric chemistry, solar-terrestrial interactions, environmental and societal impacts.
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment.

The moist static energy is a thermodynamic variable that describes the state of an air parcel, and is similar to the equivalent potential temperature. The moist static energy is a combination of a parcel's enthalpy due to an air parcel's internal energy and energy required to make room for it, its potential energy due to its height above the surface, and the latent energy due to water vapor present in the air parcel. It is a useful variable for researching the atmosphere because, like several other similar variables, it is approximately conserved during adiabatic ascent and descent.

Paul Rowland Julian, a Fellow of the American Meteorological Society, is an American meteorologist who served as a longtime staff scientist at the National Center for Atmospheric Research (NCAR), was co-author with Roland Madden of the study establishing the Madden–Julian oscillation (MJO), and contributed to the international, multi-institutional Global Atmospheric Research Program (GARP), Tropical Wind, Energy Conversion, and Reference Level Experiment (TWERLE), and Tropical Ocean-Global Atmosphere (TOGA) meteorology research programs. The MJO meteorologic phenomenon he co-discovered is the largest element of the intraseasonal variability in the tropical atmosphere, a traveling pattern arising from large-scale coupling between atmospheric circulation and tropical deep convection. Description of the MJO remains an important contribution to climate research with relevance to modern short- and long-term weather and climate modeling.
