Wintertime Atmospheric Modeling

Wintertime meteorological conditions in Utah are difficult to portray using conventional atmospheric-modeling approaches. To improve the accuracy of simulations of pollution along the Wasatch Front and Cache Valley, models need to better simulate the complex meteorological features associated with the cold-air pools that form during winter in the valleys of northern Utah. Specifically, models need to replicate the boundary layer stability that controls pollution buildup and the mountain-valley wind flows that transport pollution.
