Biography:
Dr. Jiun-Dar Chern received a BS from National Taiwan University in 1984 and a Ph. D. in Atmospheric Sciences in 1994 from Purdue University where he has developed the Purdue Mesoscale Model (PMM) and applied the model to study lee vortices, and winter cyclogenesis over the western United Stated. Form1995-2000, he worked as a Research Associate at Purdue University to develop the Purdue Regional Climate Model (PRCM) and snowpack and sea-ice models. The model has been applied to study the 1988 US drought, 1993 Midwestern flood, and 1998 flood in Eastern Asia. In 2000 he joined UMBC/GEST and worked at the DAO, NASA/GSFC to improve the physical parameterizations of the fvGCM and the interface between the fvGCM and GEOS4 data assimilation system. In 2004 he joined the modeling group at Mesoscale Atmospheric Processes Branch to develop the Multi-scale Modeling Framework or superparameterization based on the fvGCM and 2D GCE models. His main research goal is to use NASA high-resolution satellite products for evaluating and improving the cloud microphysics schemes in CRM and the representation of moist processes in climate models. |
