An Urban Parameterization for a Global Climate Model. Part I: Formulation and Evaluation for Two Cities

摘要: Abstract Urbanization, the expansion of built-up areas, is an important yet less-studied aspect land use/land cover change in climate science. To date, most global models used to evaluate effects on do not include urban parameterization. Here, authors describe formulation and evaluation a parameterization areas that incorporated into Community Land Model, surface component Climate System Model. The model designed be simple enough compatible with structural computational constraints coupled complex explore physically based processes known determining climatology. city representation upon “urban canyon” concept, which consists roofs, sunlit shaded walls, canyon floor. floor divided pervious (e.g., residential lawns, parks) impervious roads, par...
