EDUCATION:
Ph.D., Atmospheric Physics, University of Nevada, Reno
M.S., Atmospheric Physics, University of Nevada, Reno
B.S., Meteorology, National Taiwan University, Republic of China
PROFESSIONAL INTERESTS:
Dr. Chai's primary research interest is in the marine boundary layer
which includes the dynamics and microphysics of the marine boundary-layer
cloud systems, the formation and dissipation of marine fog, and the
modeling of marine boundary-layer convection. He is also involved
in research on a cloud dynamic model involving the convective turbules
and has conducted investigations of the microphysics of clouds, the
formation of droplets in clouds, and their evolution. A new thermodynamic
diagram, constructed by Drs. Telford and Chai, is the most powerful
tool available for cloud microphysics investigations. He is currently
working on several projects including: 1) integrate a dynamic aerosol
model with a mesoscale meteorology model in order to predict the evolution
of aerosol size spectra in the marine boundary layer; 2) retrieve
the microphysical properties of marine boundary layer clouds from
satellite remote sensing data; and 3) model the dispersion of gas
and particulate over complex terrain. Dr. Chai is also investigating
the role of AgI in atmospheric modification experiments by using tracers
and theoretical simulations. A new physical-chemical snow enhancement
assessment method, invented by Drs. Warburton and Chai, greatly advances
our ability to assess the effect of seeding by silver iodide on winter
orographic cloud systems.
