# Full-Scale Measurements of Wind Characteristics on a High- Rise Building during Typhoon Sarika
## 1 Introduction  
With the rapid development of data acquisition system and sensor technology, field measurement of wind characteristics on high-rise buildings under typhoon is an enduring and developing research topic. Lots of field measurements of wind characteristics of high-rise buildings during typhoons have been conducted. Since the 1990s, many scholars, represented by Professor [PERSON], have carried out massive field measurements on more than 10 super high-rise buildings in coastal areas of China [1; 2; 3; 4]. The measurements covered the wind field atop the high-rise buildings, the characteristics of internal and external pressure on the building surface, the vibration displacement and acceleration response of high-rise buildings, etc. These field measurements provide valuable references for enhancing the understanding of the wind characteristics and structural dynamic characteristics (vibration mode, natural frequency, and damping ratio) of high-rise buildings. [PERSON] et al. [5] installed the wind and structural monitoring system on Di Wang Tower under Typhoon York to monitor wind and structural response data. The field measurement data were analyzed clearly and demonstrated that the performance of Di Wang Tower is satisfactory during Typhoon York, which was a valuable finding for further wind-resistant design. [PERSON] et al. [6] conducted field measurements in typhoon Hagupit to model the spectral features of typhoon winds with critical implications on the mitigation of disproportionate damage experienced in typhoon-prone regions, and proposed a data-driven model for the wind power spectrum in tropical cyclone winds over the sea surface. [PERSON] et al. [7] studied the gust factor related to Typhoon Maemi and showed that typhoon gust factors have no significant difference from those associated with non-typhoon winds, and can be described using models developed for standard neutral boundary layer flow conditions. [PERSON] et al. [8]investigated the gust factors during Super Typhoon Hato in the South China sea, the results show that the gust factor initially increased with increasing wind speed and plateaued at wind speed between 30 and 50 m/s before exhibiting a decreasing trend until 70 m/s. [PERSON] et al. [9] investigated the gust characteristics of near-ground typhoon based on 14 sets of records observed by 4 meteorological stations during 10 typhoons, the results show that the off-sea gust factor at 10 m is 8% higher than the over-land value while other heights show little difference. [PERSON] et al. [10] conducted field measurements of two Typhoon cyclones to study the characteristics of the near-surface boundary layer, and found a region-specific wind speed power spectrum and its associated spectrum parameters that can be used for the design of wind-resistant structures in Typhoon-prone regions. [PERSON] et al. [11] analyzed the field measurement data of wind-excited vibration responses of two skyscrapers (393 and 432 m in height) during Super Typhoon Mangkhut. [PERSON] et al. [12] conducted many field measurements of dynamic responses and wind-filed characteristics on 5 high-rise buildings located in the coastal regions of Wenzhou, Xiamen and Haikou from 2008 to 2018, by which they investigated wind field characteristics of different geomorphic characteristics under typhoon and the time-domain and frequency-domain characteristics of the fluctuating wind speed acceleration response. The southeast coast of China is a typhoon-prone region, the measured high-rise building located in the coastal area of Haikou City was thus selected to monitor more typhoons considering that Hainan Island has the maximum probability of typhoon landing. The field measurement of wind characteristics atop high-rise buildings under typhoon is far from enough, especially the measured samples of wind characteristics atop super high-rise buildings under the action of strong typhoons.
