“…A residential system consists of a tilt flat panel (120 cm Â 60 cm) with a horizontal cylinder Model of a residential system (Chung et al, 2008) respectively, faces the flow direction. In addition, turbulence intensity of the incoming flow at low elevation on rooftops might be up to 20-30% (Cao et al, 2009). A preliminary study by Chung et al (2010) indicated that the uplift force (positive downward) for a solar collector model increased slightly with increase in turbulence intensity (14%).…”

“…Turbulence intensity and gust factor are two important parameters in the determination of fluctuating wind velocity components. According to the research of typhoon wind field by Choi (1983), Ishizaki (1983), a normalized empirical expression was proposed to describe the relationship between gust factor and turbulence intensity in longitudinal direction (Cao et al, 2009) Gu et al (2011), it turns out that the results calculated by the two methods are almost the same. The linear fitting method is adopted in this paper, for both the relationships of gust factors and turbulence intensities in longitudinal and lateral directions are defined as:…”

This paper studies the wind characteristics measured from two adjacent high-rise buildings. The original results of the wind measurement, including the mean wind speeds and directions, turbulence intensities, gust factors and turbulence integral length scales, are presented. The mean wind speeds and directions measured from the two buildings are very close, thus providing an opportunity to compare the wind characteristics measured on top of them through a statistic method. Therefore, the effects of mean wind speeds and directions on wind characteristics are checked. Valid results of turbulence intensities and gust factors need to meet the requirement that mean wind speed should be larger than 10 m/s and mean wind direction should lie between 40° and 105°, but it is with some hash terms for turbulence integral length scale. The strong wind data of 36h is selected to analyze some turbulence characteristics in detail, and wind spectra and correlation of wind speeds between the two buildings are also studied.

“…Baker (2007) and Holmes et al (2006) investigated the trajectory of kinds of flying debris in strong winds. There have also been many studies on the wind characteristics of strong typhoons (e.g., Powell et al, 2003;Cao et al, 2009). In addition, IAWE has paid great efforts to reduce the impact of wind hazards during the program of International Decade for Natural Disaster Reduction (IDNDR) that was initialized by the UN (Solari, 2007).…”
