Brief Research Experience

        My academic activities are devoted to the numerical model development
and simulation of cloud and mesoscale weather systems. With about 10 years
numerical modelling experience in cloud dynamics and microphysics, mesoscale,
and transportation of air pollutants, about fifteen papers have been published
in these fields.

        From 1989 to 1991 during my doctoral degree work, I designed and deve-
loped a 3D numerical cloud model with fully elastic, nonhydrostatic dynamics,
parameterized PBL, and detail microphysics processes. A large number of simula-
tions based on the model had been made to investigate the influences of ice-
phase processes, different underlying surfaces, and ambient wind shear on the
evolution, propagation, and precipitation of various types of convective storms.
The most important achievement from these research works is to reveal numeri-
cally that the ice phase microphysics in clouds tends to produce more intensive
modeling storms and, under some favorate condition, even alters their dynamic
structures and life cycle, with the implication of the significant importance of
the inclusion of ice phase processes in cloud and mesoscale models.

        In 1992 and 1993, the cloud model has been modified to contain prognos-
tic equations of different solubility air pollutants, and used to simulate the
vertical transport of gases pollutants by convective clouds. The simulations
show that deep convective storms play a key role in quick transport of high
concentrated pollutant gas from PBL upward to the mid and upper troposphere in
half hour time scale, and in dilution of the low level concentration, suggesting
the necessity of parameterizing the convective transport process in long-range
transport models.

        From 1994 to 1996, being a research fellow (post-doc fellowship) at the
Dept. of Atmospheric and Oceanic Sciences, McGill University, my research,
extending into mesoscale area, focus on the effects of deep convections on the
explosive deepening of the Atlantic marine cyclones, by using the Canadian
Mesoscale Compressible Community (MC2) Model. During this work, a highly
efficient explicit microphysics scheme has been developed and joined in the
mesoscale model's mainframe, with very encouraging performance on simulations of
both the mesoscale structures of extratropical cyclones and the evolution and
precipitation of continental mesoscale convection systems (MCS).

        From 1997 to 2001, joined the CMRP (Coastal Meteorology Research
Program) group at the University of Oklahoma as a Research Scientist. The major
task is to  improve the coastal weather prediction with Navy COAMPS model. Since
2002,  join CAPS (Center for Analysis and Prediction of Storms) working on storm
scale ensemble forecasting and calibration study and QPF verification.

        Strong computer background include experience on various workstations
(such as IBM, SGI, and DEC Alpha), and high performace computing platforms such
as Linux clusters, and PCs as well, and skillful use of FORTRAN language and
UNIX/Linux system, MSDOS and Windows 2000/XP, and working knowledge of C/C++
language.
