摘要: AbstractA forest canopy model is developed and coupled into the Regional Boundary Layer Model (RBLM) to fully consider vertical structure of tree morphology. Instead a slab surface formerly used represent trees in RBLM, new version allows refinement radiation budgets as well sensible latent heat fluxes and, hence, more precise simulation thermal impacts plantings on urban meteorological behavior. By applying this sensitivity tests are conducted explore potential different greenery scenarios environment an eastern Chinese city, Suzhou, during hot summer days. Greenings, both planting grass surfacing, beneficial cooling ambient air temperature. In general, than surfacing with same coverage. terms energy balance, coverage increasing from 0% 20%, then 40%, average net at noon (1200...
