本文详细描述了南极罗斯岛地区的三维风流特征。南极洲这一地区地形复杂，风向取决于地形和当地的气象条件。对罗斯岛地区的高分辨率区域进行了高分辨率的非静力数值模拟。根据罗斯岛地区的两种主要风流模式进行了两次模拟。第一次模拟为稳定低层大气的小风个例，第二次模拟为高风速事件。为了更全面地了解风流的动力学，包括了弗劳德数计算以及对运动方程的研究。模拟结果与以往的研究结果和观测结果具有良好的相关性，并对该地区的三维风流有了更全面的了解。除了更多的..。
Abstract A detailed description of the characteristics of the three-dimensional wind flow for the Ross Island region of Antarctica is presented. This region of Antarctica has complex topographic features, and the wind flow is dependent on the topography and the local meteorological conditions. High-resolution nonhydrostatic numerical simulations are conducted over a high-resolution domain in the Ross Island region. Two simulations are performed corresponding to the two dominant wind flow patterns in the Ross Island region. The first simulation is a light wind case with a stable lower atmosphere and the second is a high wind speed event. Froude number calculations, along with a study of the equation of motion, are included for a more complete understanding of the dynamics of the wind flow. The results of the simulations show a favorable correlation to past research results and observations, and provide a more complete understanding of the three-dimensional wind flow in the region. In addition to a more tho...
