Dr. Sen Chiao received his PhD degree from the North Carolina State University in 2003. His primary research interest is in numerical modeling with emphasis on problems in synoptic/mesoscale dynamics including: terrain-induced storms, tropical precipitation systems, land-sea-breeze convection, as well as boundary layer processes in coastal regions. He is currently involved in several projects including: 1) Investigating drainage flows, rotors and low-level jets under quiescent condition during the Terrain-Induced Rotor Experiment in spring 2006 (T-REX); 2) numerical modeling and data analysis of the African Multidisciplinary Monsoon Analyses (AMMA) field experiment in 2006; 3) Landfalling hurricane intensity changes.
