碩士 / 國立臺灣大學 / 大氣科學系 / 81 / The dispersion of contaminants in the sea breeze is calculated
by a two-dimensional diffusion model.Three prognostic equations
are employed for the concentration,the concentration flux,and
covariance of temperature and concentration. The environmental
background,which includes the mean wind,the virtual potential
temperature,the turbulent kinetic energy and other second
moments,is generated from a mesoscale model. The mesoscale
model includes budget equations of surface energy and moisture
fields,as well as turbulence and radiation parameter- ization.
As in a convective boundary layer,for an elevated point source
in the sea breeze,the plume concentration centerline descends
until it intercepts the ground,then it rebounds and returns to
the mixed layer.
