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...

Data 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...

Wind observations above an urban river using a new lidar technique, scintillometry and anemometry.

Airflow along rivers might provide a key mechanism for ventilation in cities: important for air quality and thermal comfort. Airflow varies in space and time in the vicinity of rivers. Consequently, there is limited utility in point measurements. Ground-based remote sensing offers the opportunity to study 3D airflow in locations which are difficult to observe with conventional approaches. For t...

Gust Loading Factor : New Model

Wind loads on structures under the buffeting action of wind gusts have traditionally been treated by the ‘‘gust loading factor’’ (GLF) method in most major codes and standards around the world. In this scheme, the equivalent static wind loading used for design is equal to the mean wind force multiplied by the GLF. Although the traditional GLF method ensures an accurate estimation of the displac...
