A Review of the Influential Factors of High Wind Characteristic Parameters in Western China

There have long been numerous studies on wind, an erratic turbulent movement, with the expectation to describe it precisely by theoretical model. However, until now, only the characteristics of wind within 100 m above ground level have been clearly understood. The frequently-used wind characteristic parameters are wind speed, wind direction, angle of attack, turbulence strength, turbulence integral scale, and turbulence power spectrum. The main accesses to values of wind characteristic parameters are: field measurement, wind tunnel test, and numerical simulation. Supplementary to one another though, the three accesses may lead to inconsistent computation results, attributing mainly to non-uniform analytical methods of field measurement data and poor simulation precision. Therefore, it is necessary to start respectively from the three accesses to research the influential factors of wind characteristic parameters.
