Special Issue Information

Dear Colleagues,

A wind gust is commonly defined as a sudden but short-lived increase in wind speed. Wind gusts can threaten the safety or serviceability of various man-made objects, such as aircraft, trains, fan blades, buildings, bridges, and other wind-sensitive civil structures. Mechanisms for the generation of wind gusts are complicated. Wind gusts may be attributed to the internal structures of violent storms (e.g., tropical cyclones, downbursts, tornadoes), the influence of orographic/topographic features, deep convection, or combinations of the above factors. Such complexities lead to a distinct spatial and temporal variability of a wind gust. During the past several decades, continuous efforts have been made to understand this phenomenon. Despite the outstanding achievements that have been made, much still remains to be further explored. First, most existing studies have focused on the temporal features observed at a single point or at a limited number of points, while spatial features have been relatively less investigated.

Meanwhile, advanced devices or techniques for high-quality and flexible observations of wind gusts, especially in the core regions of typical storms, are badly needed. Moreover, reliable forecasts are of critical importance for policymaking and the application of measures for the mitigation of wind-induced disasters, but most operationally used numerical weather prediction models continue to exhibit systematic errors, even at the price of huge computational resources. Therefore, more efforts are required to facilitate effective and efficient forecasts.

We look forward to your submissions, and to achieving a Special Issue representing the growing community of scientists involved in the observation, process, and prediction of gust wind.

Developing the engineering design standard of wind speed is a key aspect of the climate research in the Yangtze River Inland Waterway (YRIW), which is highly sensitive to extreme weather and climate processes. An engineering design wind speed projection model was established to evaluate the distribution of extreme wind speeds in the YRIW region at spatiotemporal scales from 1979 to 2100, integrating the Weibull distribution and generalized extreme value (GEV) distribution characteristics. We also used high-precision climate model products and integrated analysis methods to predict the evolution of engineering design wind speeds in the study area in the future. The results show that: (1) The maximum wind speed in the study area shows a decline—recovery trend in the historical period in general and a weak increase in Wuhan and Shanghai. (2) The maximum wind speed does not follow the Weibull distribution, and the extracted extreme wind speed types include type I, II, and III GEV distributions. (3) The updated inland port project design wind speed can meet the climatic and topographic characteristics of the YRIW. (4) The model of CNRM-CM6-1-HR product accurately captures the spatial and temporal characteristics of the maximum wind speed. (5) In the future, the design wind speed shows a slight decrease in Shanghai, Jiujiang and Yueyang. These findings provide a scientific theoretical reference and engineering reference for the development of design wind speeds for inland port projects at various cross-sections in the YRIW.
