在本研究中，天气研究和预报（WRF）模型用于量化土地利用和覆盖变化（LUCC）对近地表风速（SWS）的影响。模拟结果表明，基于2010年代土地利用覆盖数据（LUC10）的SWS低于基于1980年代土地利用覆盖数据（LUC80）的SWS，相差0.17 m s−1； LUCC 效应还导致强风概率降低 9.0%。 LUCC 效应会引起粗糙度长度的显着变化，导致阻力系数和摩擦速度发生变化，从而降低 SWS。粗糙度长度增加 0.1 m 可能会导致阻力系数增加 0.003，摩擦速度增加 0.015 m s−1。不同地区LUCC对SWS变化的贡献不同。东北地区SWS的增加是由落叶阔叶林向落叶针叶林、混交林和农田的变化引起的，这些变化导致地表粗糙度长度、阻力系数和摩擦速度降低。长江中游地区SWS的显着减少是由封闭灌木丛和农田/自然植被镶嵌区向常绿阔叶林和落叶阔叶林的转变引起的。山东半岛、京津冀地区、长三角和珠三角地区的SWS减缓可归因于城市和建成区的扩张以及耕地和耕地/自然植被镶嵌体的减少。摩擦风模型 (FWM) 也揭示了 LUCC 引起的 SWS 减慢；然而，FWM 显示了 LUCC 对 SWS 减少的更显着影响。
In this study, the Weather Research and Forecasting (WRF) model is used to quantify the effects of land use and cover change (LUCC) on the near-surface wind speed (SWS). The simulated results show that the SWS based on land use cover data for the 2010s (LUC10) is lower than that based on land use cover data for the 1980s (LUC80) by a difference of 0.17 m s−1; the LUCC effects also result in a decrease of 9.0% of the probability of strong wind. The LUCC effects induce significant alteration of the roughness length, causing changes in the drag coefficient and friction velocity, and thereby decrease SWS. A 0.1 m increase in roughness length could cause a 0.003 increase in drag coefficient and a 0.015 m s−1increase in friction velocity. The contributions of LUCC to the SWS changes vary among different regions. The increase of SWS in Northeastern China is caused by the changes from deciduous broadleaf to deciduous needleleaf forests, mixed forests and croplands, and these changes decrease the surface roughness length, drag coefficient and friction velocity. The significant decrease of SWS over the middle reaches of the Yangtze River is induced by the changes from closed shrubland and cropland/natural vegetation mosaic to evergreen broadleaf and deciduous broadleaf forest. The slowdown of SWS over the Shandong Peninsula, the Beijing–Tianjin–Hebei region, the Yangtze River Delta, and the Pearl River Delta can be attributed to the extension of urban and built-up areas and the decrease of croplands and the cropland/natural vegetation mosaic. The slowdown in SWS caused by LUCC is also revealed by the friction wind model (FWM); however, the FWM presented more significant effects of LUCC on decrease in SWS.
