Gust-front factor: A new framework for the analysis of wind load effects in gust-fronts
In comparison with atmospheric boundary-layer winds, which are customarily treated as stationary, gust-front winds such as a thunderstorm/downburst exhibit strong nonstationarity. In storms characterized by a gust-front, wind speed changes rapidly during a short time period. In order to realistically describe attendant loads effects, a new analysis framework is presented which is named the gust...
متن کاملDescription and Simulation of Gust Front Wind Field
An efficient model for simulating gust front wind field is proposed based on the time-frequency description of the wind field. Traditionally, transient or non-stationary random processes are simulated to account for amplitude modulations invoking envelop processes to shape these modulations. In this study, a time-frequency based scheme is introduced to account for both modulations in amplitude ...
متن کاملGlobal Gust Climate Evaluation and Its Influence on Wind Turbines
Strong gusts negatively affect wind turbines in many ways. They (1) harm their structural safety; (2) reduce their wind energy output; and (3) lead to a shorter wind turbine rotor blade fatigue life. Therefore, the goal of this study was to provide a global assessment of the gust climate, considering its influence on wind turbines. The gust characteristics analyzed were: (1) the gust speed retu...
متن کاملA machine-learning algorithm for wind gust prediction
Physical damage to property and crops caused by unanticipated wind gusts is a well understood phenomenon. Predicting its occurrence continues to be a challenge for meteorologists and climatologists. Various approaches to gust occurrence model building have been proposed. The very nature of the event is problematic because of its brief duration following a rapid change of state in wind velocity ...
متن کاملData Mining Methods to Generate Severe Wind Gust Models
Gaining knowledge on weather patterns, trends and the influence of their extremes on various crop production yields and quality continues to be a quest by scientists, agriculturists, and managers. Precise and timely information aids decision-making, which is widely accepted as intrinsically necessary for increased production and improved quality. Studies in this research domain, especially thos...
