In this study, we conducted an intensive meteorological observation at Taipei 101 building to take the vertical in-situ observation. Starting from January of 2011, the minute-resolution observations through WXT520 integrated weather sensors were installed on the 34F (151m) and 82F (352m) balcony, started from January of 2011 until now. In addition, there were 34 radiosonde observations at NTU campus (3-km away of Taipei 101) for validation of skyscraper observations. The analysis shows that the deviation of air temperature between 34F and 82F captures the characteristics of boundary temperature inversion very well. The diurnal and seasonal variation of temperature and humidity field can also be seen from the hourly data. The wind speed at 34F layer is significantly larger than 82F from WXT520, compared with the wind speed from radiosonde observations, the wind speed is also smaller at Taipei 101 at the same altitude. Meanwhile, cases with strong temperature inversion are analyzed in this study. AutoCad software and a high resolution CFD model (Cradle Stream Model) are used to simulate the micro-scale wind field surrounding Taipei 101. The simulations showed that the wind speed decreases in front of and behind the building and behind the building, and increases on the sides. The decreasing ratio of wind speed from observation and simulation is not consistent with each other.More simulations from different wind directions were established to provide an corrected reference on wind field observations on Taipei 101 balconies. 林博雄 2012 學位論文 ; thesis 95 zh-TW |

碩士 === 國立臺灣大學 === 大氣科學研究所 === 100 === High buildings (skyscraper) are the significant landmarks of urban cities. In this study, we conducted an intensive meteorological observation at Taipei 101 building to take the vertical in-situ observation.
Starting from January of 2011, the minute-resolution observations through WXT520 integrated weather sensors were installed on the 34F (151m) and 82F (352m) balcony, started from January of 2011 until now. In addition, there were 34 radiosonde observations at NTU campus (3-km away of Taipei 101) for validation of skyscraper observations.
The analysis shows that the deviation of air temperature between 34F and 82F captures the characteristics of boundary temperature inversion very well. The diurnal and seasonal variation of temperature and humidity field can also be seen from the hourly data. The wind speed at 34F layer is significantly larger than 82F from WXT520, compared with the wind speed from radiosonde observations, the wind speed is also smaller at Taipei 101 at the same altitude.
