This effect is particularly important for structures on the boundary of different topographical features, such as those in Chicago, which sits next to Lake Michigan and thus feels the brunt of wind sweeping in from across the surface of the water while at the same time feeling the effects of the polar jet stream, or Los Angeles, which is positioned between the ocean and a range of tall mountains and so experiences the turbulence of ocean winds hitting the land. Furthermore, because the acceleration or deceleration of the velocity profile diffuses itself through turbulence, the higher up a structure, the more turbulence it will experience (Azad 1993).

Computational Fluid Dynamics

Having provided an overview of the atmospheric boundary layer and the areas of the ABL that most influence wind effects on high-rise buildings, it will now be possible to discuss computational fluid dynamics in greater detail in order to demonstrate...
