Abstract
Available meteorological data are usually unsuitable for application to structural problems for a variety of reasons. The most obvious deficiency involves instrument location in the three-dimensional sense. Most meteorological observations have been obtained at low elevation in open country, and they therefore do no reveal the wind structure at the typical heights of modern urban buildings. Furthermore, few of the data have been processed to reflect the turbulent structure of flow. More subtle problems are involved with the failure of any current programs to define the horizontal structure of turbulence, although a small number of appropriate studies have been made in the vertical. Very important, too, is the lack of data taken under extreme meteorological conditions, such as thunderstorms and hurricanes. These deficiencies derive in part from the difference in objectives that have led to existing meteorological programs and those that would suit the structural engineer, but they are also associated with the failures of the latter to define his requirements. An experimental program that may fill some of the gaps is outlined for discussion and criticism.
