摘要: Abstract Velocity data were obtained from sonic anemometer measurements within an east–west-running street canyon located in the urban core of Oklahoma City, Oklahoma, during Joint Urban 2003 field campaign. These used to explore directional dependence mean flow and turbulence a real-world canyon. The along-canyon vortex that is key characteristic idealized studies was not evident wind data, although sensor placement optimized for detection such structures. Instead, surface imply regions horizontal convergence divergence exist canopy, which are likely caused by taller buildings diverting winds aloft down into canopy. details these processes appear be dependent on relatively small perturbations prevailing direction. Turbulence intensities interior appeared have more direction than they did in...
