Professor Carlos Roberto Mechoso is a professor of Atmospheric Dynamics in the Department of Atmospheric and Oceanic Sciences at the University of California, Los Angeles. His current research interests are ocean-atmosphere interactions, numerical weather prediction, meteorology and climatalogy of the Southern Hemisphere, and high performance computing. He is the author of more than 150 scientific publications in his fields of interest. The goal of Professor Mechoso's research is to increase the understanding of climate variability using analyses of highly realistic simulations with numerical models, complemented by studies with observational data. Targeted topics have been El Nino/Southern Oscillation and its impacts, American monsoon systems, stratospheric warnings, instabilities on atmospheric fronts, and distributing computing for climate modeling.

Professor Mechoso is the founding Chair on the panel on Variability of the American Monsoon Systems (VAMOS) of the World Climate Research Programme (WCRP). Currently, he chairs the Science Working Group of the WCRP/VAMOS Ocean-Clouds-Atmosphere-Land Studies (VOCALS) program. He is also a member of the WCRP/VAMOS panel, and the Science Advisory Committee of the International Pacific Research Center, U. Hawaii. Professor Mechoso has been appointed to the WCRP/ClIVAR Science Steering Group for the period of 2007-2009.
