The Theoretical Study of Diurnal Mountain-Valley Circulation.
Abstract
Theoretical models are developed, using both numerical and analytical approaches, to investigate the circulation including the upper air flow over a two-dimensional undulating mountain-valley terrain. The interaction between the prevailing flow and the thermally induced flow due to differential heating over a typical mountain-valley terrain is studied. The spatial distribution of various meteorological variables for various thermal surface conditions corresponding to different times in the day and different turbulent flow conditions, are sought. Since the ground temperature or eddy heat flux transport to and from the ground surface in a mountain-valley terrain is vital to the transient problem of the wind circulation, the determination of surface temperature from the complicated energy equation is also investigated.
