WIND FLOW OVER COMPLEX TERRAIN: A HISTORICAL PERSPECTIVE AND THE PROSPECT FOR LARGE-EDDY

摘要: The development of our understanding turbulent flow over complex terrain is described. Despite considerable advances, there are still gaps in knowledge. Large-eddy simulation such flows now becoming possible. This may stimulate further advances but it computationally very demanding. application this technique to hills discussed. It fifty years since Queney published his review theoretical models inviscid and mountains (Queney, 1948). This, together with Scorer's analytical solutions for lee waves a year later (Scorer, 1949), sparked off surge research area that continues various guises day. seems fitting time, therefore, reflect on work look ahead the next few years. There have been several comprehensive, technical reviews all aspects field which interested reader referred (e.g., Taylor et al., 1987; Blumen, 1990; Kaimal Finnigan, 1994; Belcher Hunt, 1998). In contrast, aim here not detailed subject rather place current standing within historical context thereby consider limitations state-of-the-art. We start by considering what challenges motivations study atmospheric mountains. Then, starting from others, brief outline progress past 50 given, addressing met. brings us present time number areas outstanding. scope, also some hope indeed Finally, possible route forward, large-eddy simulation, ?
