Abstract
A Fourier series is fitted to a set of 10 min mean pressure coefficient data for the Silsoe Structures Building. Corrections made to this function illustrate the effect of directional variations in rounding the C p( θ) relationship. It is shown that in a region of local extreme the difference between C p( θ) and C p( θ) may be more than 0.25. These series are also used to give an estimate of the contribution to the fluctuating pressures which results from directional variations. It is shown that this estimate closely matches observed data.
