Xiaomin Chen, Ph.D. Assistant Professor, Atmospheric and Earth Science Contact 320 Sparkman DriveCramer Research HallRoom 3050Huntsville, AL 35899 Campus Map firstname.lastname@example.org Biography Dr. Xiaomin Chen’s research focuses on different aspects of tropical cyclones, including rapid intensification, boundary layer processes, and numerical modeling and forecasts. His research is aimed at understanding the boundary layer processes that contribute to the intensity and structural changes of tropical cyclones. To achieve this goal, his current research utilizes a combination of manned and unmanned aircraft observations and turbulence-resolving large-eddy simulations to improve the modeling of boundary-layer processes in hurricane conditions. A recently developed boundary layer scheme has been implemented into NOAA’s next-generation hurricane forecast model, Hurricane Analysis and Forecast System. Graduate Students Opportunities Dr. Chen’s research group is admitting master or Ph.D. students in AES for Fall 2023 to study boundary-layer processes that impact hurricane intensity and structural changes. Students will have the opportunity to collaborate with NOAA scientists in processing in-situ observational data and analyzing the output from NOAA's next-generation hurricane forecast model. Please reach out to Dr. Chen for more information.
