Abstract
A turbulent, two-dimensional sea breeze model is solved by the finite analytic method on a regular grid using the momentum weighted interpol ation method. A k-epsilon turbulence model is used to simulate the tur bulent aspects of the planetary boundary layer. The spatial structure of the model circulation, including inflow depth and penetration, were in close agreement with observational studies. The magnitude of the m ean horizontal speed reached a maximum of 3.4 ms-1, somewhat less than those reported in many observational studies. However, the magnitude of the vertical velocity reached a maximum of 0.7 ms-1, similar to spe eds observed in experimental studies. Model results for quantities of turbulent kinetic energy, dissipation of turbulent kinetic energy, and turbulent viscosity showed very close agreement with those measured i n experimental studies. The maximum value of turbulent kinetic energy was nearly 2 m2s-2, while the rate of dissipation of turbulent kinetic energy reached a maximum value of 11.8 cm2s-3. The turbulent viscosit y attained values of nearly 100 m2s-1.
