近地面微氣象學是在探討發生在大氣邊界層(或可稱為行星邊界層)的各種大氣現象,在大氣邊界層中,大氣與地球表面具有顯著的動量,質量及熱量交換, 而其觀測特徵如溫度,速度及密度具有高度的變異性,且這些現象主要牽涉到小尺度的過程。雖然大氣邊界層只佔大氣層的極小部分。然而其伴隨的小尺度物理過程對於人類活動及生物生存有重要影響。本課程內容將針對下列主題作有系統的闡釋:1.微氣象學簡介 2.近地面層的能量收支 3.土壤溫度與熱量傳送 4.大氣邊界層的溫度與濕度 5.大氣邊界層的氣流特性。
The scope of micrometeorology is limited to only those phenomena occurring in the atmospheric boundary layer (or called planetary boundary layer). Significant exchange of momentum, heat, or mass takes place between the surface and the atmospheric air. Sharp variations in the properties of the flow, such as temperature, velocity, and mass, also occur in the boundary layer. These characteristics are primarily related to the small-scale processes. Although the atmospheric boundary layer comprises only a tiny fraction of the atmosphere, its associated small-scale physical processes are important for the human activities and even survival of life on earth. The course outline will primarily include: (1) Introduction, (2) Energy Budget near the Surface, (3) Soil Temperature and Heat Transfer, (4) Air temperature and Humidity in the Atmospheric Boundary Layer, (5) Wind Distribution in the Atmospheric Boundary Layer.
