Professor Lindzen is a dynamical meteorologist with interests in the broad topics of climate, planetary waves, monsoon meteorology, planetary atmospheres, and hydrodynamic instability. His research involves studies of the role of the tropics in mid-latitude weather and global heat transport, the moisture budget and its role in global change, the origins of ice ages, seasonal effects in atmospheric transport, stratospheric waves, and the observational determination of climate sensitivity. He has made major contributions to the development of the current theory for the Hadley Circulation, which dominates the atmospheric transport of heat and momentum from the tropics to higher latitudes, and has advanced the understanding of the role of small scale gravity waves in producing the reversal of global temperature gradients at the mesopause.
He pioneered the study of how ozone photochemistry, radiative transfer and dynamics interact with each other. He is currently studying the ways in which unstable eddies determine the pole to equator temperature difference, and the nonlinear equilibration of baroclinic instability and the contribution of such instabilities to global heat transport. In the past few years, he has been studying the influence of temperature on cumulus convection and its role in generating cirrus decks. The results so far strongly suggest a powerful negative feedback in climate.
He has developed models for the Earth's climate with specific concern for the stability of the ice caps, the sensitivity to increases in CO2, the origin of the 100,000 year cycle in glaciation, and the maintenance of regional variations in climate.
Prof. Lindzen is a recipient of the AMS's Meisinger, and Charney Awards, and the AGU's Macelwane Medal. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and a Fellow of the AAAS. (Ph.D., '64, S.M., '61, A.B., '60, Harvard University)
