    Abstract: This research intends to investigate the cross spectrum characteristics of wind pressure fluctuations on the surface along the meridian of domed roofs under turbulent wind flows. Wind pressure experiments of domed roofs are conducted considering two roof curvatures and three heights of side walls. From the experimental results, various distribution types of co-coherences are examined and the traditional exponential decaying form is shown insufficient to approximate the general characteristics of co-coherences. By combining the proposed models by Uematsu et al and Kanda et al and also a phase shift parameter included, the approxi-mation model is then improved to represent the observed coherences generally.
