A symposium in honor of Professor Akio Arakawa: Modeling Convection, Clouds and Climate Systems

October 17-18, 2022, Los Angeles, California
Roger Wakimoto, UCLA Vice Chancellor for Research & Creative Activities
Rong Fu, Professor, UCLA Atmospheric & Oceanic Sciences 
David Randall, University Distinguished Professor, Colorado State University

This two-day symposium will foster scientific exchange in the fields of convection and clouds and climate modeling, to honor the contributions of Professor Akio Arakawa. A set of invited talks will provide the broad context for discussion and poster sessions that reflect the advancements and explore new directions in the areas to which he contributed, and to engage and inspire students and early career scientists to pursue careers in climate modeling and related areas. A public lecture aimed at a broad audience will be given by Professor Kerry Emanuel of MIT.

Professor Arakawa was a pioneer in the development of atmospheric global circulation models, which now are essential tools for both weather forecasting and climate change studies. He was an inspiring and generous mentor for his students and co-researchers. His scientific papers are models of clarity. His graduate-level classes were challenging and rewarding. He trained and inspired multiple generations of researchers and leaders in the field of global atmospheric models. This symposium will provide a great opportunity for current students and early career scientists nationwide to interact with leading scientists in the field of atmospheric and climate modeling, and to learn from Prof. Arakawa’s career.

Attendance is open to the community. We encourage abstract submissions from anyone with relevant research, though a presentation is not required to attend the symposium.

If you would like to make a donation in honor of Prof. Akio Arakawa, please click here. Symposium registration fees will be directed to the Akio Arakawa Fund. It is our goal to convert this current expenditure fund to an endowment and grow the endowment over time with support from family and friends. If a minimum of $100,000 in gifts or pledges is raised by December 31, 2022, the fund may be converted to an endowment fund whose purpose will be determined by the Arakawa family.
