The effect of microscale urban canyon flow on mesoscale puff dispersion

摘要: When modeling mesoscale plume or puff transport over distances of one to ten kilometers, the initial small-scale near-source effects are often ignored parameterized in a crude way. If release is an urban environment, buildings and other structures can significantly impact local dispersion (e.g., Davidson et al., 1995). In this paper, authors investigate whether building-scale important on longer time-scale process.
