Hirofumi Tomita

Hirofumi Tomita is the team leader of the Computational Climate Science Research Team at RIKEN Center for Computational Science (R-CCS). He studied aerospace engineering at the University of Tokyo and acquired his Dr. Eng. in 1999. He has researched atmospheric modeling as a researcher at the Japan Agency for Marine-Earth Science and Technology from 1999 to 2010. He has been in his current position since 2011. Until March of this year, he had also been a deputy project leader in charge of application development in the co-design of Fugaku. 

His research and development interests include modeling atmospheric dynamics, cloud microphysics, and boundary layer turbulence. He is particularly interested in modeling geophysical fluid dynamics. He is one of the pioneers of high-resolution climate models. He conducted the world's first global cloud-resolving experiment, in which the behavior of the cloud cluster with the hierarchical structure was successfully reproduced. The model construction and the above discovery lead to his high reputation. His current research interests are to study why clouds self-organize with a hierarchical structure from the perspective of energy balance in the atmosphere. Modeling using data science is a recent target.
