中文摘要 | 该文应用美国NCAR三维非静力平衡中尺度模式MM5研究了近岸斜坡地形对海岸带微气候特征的影响,得到了不同位置、不同坡度的斜坡地形条件下海岸带微气候要素的日变化过程,并与无地形条件下的情况进行了对比。计算结果表明,在陆地下垫面升温的初始阶段,斜坡地形的热力效应起主导作用;在海陆风发展过程的大部分时间里,斜坡地形的动力效应起主导作用。此外,近岸斜坡地形与岸线的距离以及地形坡度等也会对海岸带微气候要素产生影响。; The fifth-generation NCAR/Penn State nonhydrostatic dynamics mesoscale model (MM5) was used for the numerical study of the microclimate of the coastal area where an inclined surface is in presence. The main factors representing the coastal microlimate are computed under the conditions of different slope locations and different grades. It is shown that the sea/land breeze has been hastened at the beginning due to the existance of the slope. When the sea/land breeze develops, the slope wakes as a barrier which depresses the surface pressure and reduces the wind velocity. The main factors representing the coastal microlimate are also influenced by the slope location and grades.; 国家自然科学基金(10772099) |
