چکیده

A numerical model has been used to characterize the development of a region of 6 enhanced cooling, in an alpine valley with a width of order 10 km, under decoupled stable 7 conditions. The region of enhanced cooling develops largely as a region of relatively dry 8 air that partitions the valley atmosphere dynamics into two volumes, with air flows partially 9 trapped within the valley by a developing elevated inversion. Complex interactions between 10 the region of enhanced cooling and the downslope flows are quantified. The cooling within 11 the region of enhanced cooling and the elevated inversion is almost equally partitioned be12 tween radiative and dynamics effects. By the end of the simulation, the different valley at13 mosphere regions approach a state of thermal equilibrium with one another, though this can 14 not be said of the valley atmosphere and its external environment. 15

Pollutant Dispersion in a Developing Valley Cold - Air Pool

Pollutants are trapped and accumulate within cold-air pools, thereby affecting air 5 quality. A numerical model is used to quantify the role of cold-air-pooling processes in 6 the dispersion of air pollution in a developing cold-air pool within an alpine valley under 7 decoupled stable conditions. Results indicate that the negatively buoyant downslope flows 8 transport and mix pollutants into t...

Interactions between downslope flows and a developing cold-air pool

Downslope flows and regions of enhanced cooling have important impacts on society and the environment. Parameterisation of these often subgrid-scale phenomena in numerical models requires a sound understanding of the underlying physical processes, which has been the overarching aim of this work. A numerical model has been used to characterise the development of a region of enhanced cooling in a...

Meteorological Processes Affecting the Evolution of a Wintertime Cold Air Pool in the Columbia Basin

Meteorological mechanisms affecting the evolution of a persistent wintertime cold air pool that began on 2 January and ended on 7 January 1999 in the Columbia basin of eastern Washington were investigated using a mesoscale numerical model together with limited observations. The mechanisms include surface radiative cooling and heating, large-scale subsidence, temperature advection, downslope war...

Evolution of Cold-Air-Pooling Processes in Complex Terrain

Elucidating cold-air-pooling processes forms part of the longstanding problem of 5 parametrizing the effects of complex terrain in larger-scale numerical models. The Weather 6 Research and Forecasting model has been set-up and run at high resolution over an ideal7 ized alpine-valley domain with a width of order 10 km, to investigate the four-dimensional 8 variation of key cold-air-pooling forci...

The Impact of Lee-side Static Stability on the Distribution of Orographic Precipitation

Numerical simulations are presented to examine the effect of the lee-side static stability on the spillover of orographic precipitation. The results show that the presence a cold-air pool in the lee of a mountain ridge greatly increases the precipitation spillover because the cold pool suppresses the lee-side downslope air motion that otherwise leads to a rapid evaporation of the precipitation....
