台北都會區由於高樓林立使得低層風場型態更形複雜，造成都會區街道尺度微氣象研究的挑戰，影響近地面人為與自然污染物的傳輸及擴散現象，本研究計畫將應用數值模擬及流體力學理論，探討超高型建築物週遭的風場結構及建築物結構群繞流之剪切流與尾流干擾的物理機制。本文研究將以台北101金融大樓附近的主要建築物為例，探討建築物所承受之風壓及風場變化，並對風場所導致之環境影響提供有用的數據。不穩定流動現象是指由一種的流動類型過渡到另一種類型上，進而產生不穩定的風場。本研究計畫的研究重點將放在風場不穩定的物理機制、不穩定現象的結果以及它在工程的應用等。本研究除了對瞭解大氣風壓的物理現象有所幫助外，對於日後改善噪音之設計也可提供有價值的參考資料。

Due to the high buildings landscape in cities, the pattern of wind field becomes complex more than before, and is a big challenge to street-scale micrometeorology study in the transportation of anthropogenic and natural pollutants. This project will use computational fluid dynamics (CFD) model, which combines the feature of atmospheric circulation and computational fluid dynamics, to simulate the details of the wind field, shear flow, vortex dynamics and the corresponding physics behavior surrounding Taipei 101 skyscraper and high buildings canopy in Xinyi district of Taipei. This simulation could provide useful concept of wind flow on the pollutant dispersion track in street canopy and disturbance development in the atmospheric boundary layer. The results will be utilized to understand the impact of skyscraper buildings on physics of wind pressure, turbulence and noise. It could also provide a concept sample on the street canopy scale of atmospheric dispersion.
