Abstract: Smoke from wildland burning in association with fog has been implicated as a visibility hazard over roadways in the United States. Visibilities at accident sites have been estimated in the range from 1 to 3 m (extinction ...

Abstract: Rainfall, wind and temperature data at the surface for a mesoscale area surrounding St. Louis, Missouri for seven summer days in 1975 were used to determine qualitative and quantitative relationships between divergence, ...

Abstract: Bendway weirs are hydraulic control structures found in watercourses that range in scale from small streams to large rivers. They are designed to be submerged, broad-crested weirs, typically placed in groups on the outer ...

Abstract: The ability to accurately simulate sediment transport processes in natural and engineered systems is crucial to both engineers and scientists. Many researchers have worked on the development of methods that yield reliable ...

Abstract: Primitive equation initialization, applicable to numerical prediction models, has been studied by using principles of variational calculus and the appropriate physical equations: two horizontal momentum, adiabatic energy, ...

Abstract: Tiny pressure gradient forces caused by hydrostatic truncation error can overwhelm minuscule pressure gradients that drive shallow nocturnal drainage winds in a mesobeta numerical model. In seeking a method to reduce these ...

Abstract: Single- and multiple-Doppler radar systems are increasingly being used to monitor circulations within the clear-air boundary layer where the scatterers may be gradients of the refractive index or biota or a combination of ...

Abstract: Starting with Arakawa and Lamb?s second-order C-grid scheme, this paper describes the modifications made to the dynamics to create a C-grid atmospheric model with a variable number of cells for each vertical column. Where ...
