Modeling and measurements of nocturnal drainage flows along the Front Range of the Rocky Mountains
Abstract
In support of the DOE ASCOT program Lawrence Livermore National Laboratory has analyzed the wind, temperature, and net radiation measurements acquired by the network of sensors situated within and outside the Coal Creek Canyon drainage area during 1991. It is shown that strong cooling rates, between 50--80 W/m{sup 2}, generate will defined drainage flows with a maximum speed of approximately 6 m/s. A cooling rate of 15--30 W/m{sup 2}, produces a significantly weaker drainage flow and further reduction of the cooling rate results in the failure of any significant drainage flows to form. In an attempt to further understand these flows researchers conducted numerical simulations of two representative flows.
