| 摘 要： | 利用宾州／美国国家大气研究中心的ＭＭ５模式来模拟澳门的海陆风和珠江口的三维风场。模式设计为四重套网格,分辨率分别为 １ｋｍ,３ ｋｍ,９ ｋｍ,２７ ｋｍ。使用常规观测资料作为初始场,模拟时间为３０小时。结果表明采用高分辨率（１ｋｍ）模拟能很好地捕捉到澳门的海风和陆风。海风锋和热力内边界层也清楚可见。如果最小分辨率为３ ｋｍ,则只捕捉到海风,陆风却模拟不出来。

| Abstract: | PSU/NCAR MM5 was utilized to simulate the sea-land breeze circulation in Macao and the three-dimensional flow around the Pearl River estuary. Four two-way nested grids having resolution of 1, 3.9. and 27 km were included in the simulation. It was initialized with conventional observational data, and a 30 h simulation and analysis of one sea-land breeze case were performed. It was shown that the model with a finer resolution (1 km) captures the sea breeze and land breeze in Macao with reasonable skill. The sea breeze front and the thermal internal boundary layer (TIBL) were also obviously revealed. However, the coarser horizontal resolution (3 km) could capture the sea breeze but not the land breeze. |
