Research Interests: 

  • the microphysical structure of snow bands in winter cyclones
  • the role of cloud microphysical processes in mesoscale convective systems (MCSs) and storms
  • the properties of tropical clouds generated by deep convection
  • the role of cloud microphysical processes in the rapid intensification of tropical cyclones
  • processes controlling the amount of supercooled water and freezing drizzle in clouds
  • how aerosols and other synoptic conditions affect the evolution of clouds in the Arctic and over the Southern Oceans
  • the transmission of radiation through the cloudy atmosphere
  • the representation of clouds in climate and weather models, and especially the development of a stochastic framework for representing cloud processes
  • the impact of aerosol particles on the water and energy budgets of clouds
  • the impact of biomass burning on cloud properties
  • the retrieval of cloud properties from space-, air- and ground-based remote sensors
  • the use of air- and ship-based instrumentation for measuring the properties of clouds

Online Research Profiles: 

Greg McFarquhar received his B.Sc. in mathematics and physics from the University of Toronto, Canada in 1987. Thereafter, he changed his field of study to atmospheric sciences and received his M.Sc. (1989) and Ph.D. (1993) also from the University of Toronto, but specializing in cloud physics. Greg spent two years as a postdoctoral fellow at the Scripps Institute of Oceanography in La Jolla, California (1993-94) and worked at the National Center for Atmospheric Research in Boulder, Colorado (1995-2001; 2015-16), the University of Illinois (2001-17) and the University Blaise Pascal in Clermont, France (2012) before joining the faculty at the University of Oklahoma in Aug. 2017 where he also serves as Director of the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS). He is the outgoing chair of the American Meteorological Society Committee on Cloud Physics and currently Vice-President of the International Commission on Clouds and Precipitation. He is the chief editor for the American Meteorological Society’s Monographs Collection, an associate editor for the Quarterly Journal of the Royal Meteorological Society, and has active research grants from the National Science Foundation (NSF), the Department of Energy (DOE), the National Aeronautics and Space Administration (NASA), and the National Oceanic and Atmospheric Administration (NOAA). He has formerly served as the Chief Scientist for the Atmospheric Radiation Measurement (ARM) Program’s Aerial Facilities (AAF). He has 149 publications in the refereed literature, an h-index of 45, and has made over 480 presentations at conferences and working group meetings. He has participated in or led 25 different air- or ship-based cloud measurement field campaigns, and is a Fellow of the American Meteorological Society. Interested candidates for graduate studies or postdoctoral positions are encouraged to contact him for more information (mcfarq at
