A numerical model study of nocturnal drainage flows with strong wind and temperature gradients

A numerical model study of nocturnal drainage flows with strong wind and temperature gradients

Journal of Applied Meteorology 28(7): 545-554

A second-moment turbulence-closure model was used to simulate nocturnal drainage flows observed in Brush Creek, Colorado. In order to simulate the observed strong wind direction shear and temperature gradients two modifications were added to the model. The strong wind direction shear was introducing a 'nudging' term in the equation of motion to guide the modelled wind in the layers above the ridge top toward the observed wind direction.
