Abstract:Based on the historical hourly wind observation data of eight coastal and inland automatic weather stations in Shenzhen from 1 June 2007 to 1 June 2017, this study explores the seasonal gust characteris tics and the feature of the gust factors for the eight stations. The results show that winds at coastal stations are generally stronger than the winds at inland stations. The maximum gust at the eight stations due to typhoons in summer and autumn is generally stronger than the maximum gust at these stations due to cold front in winter and spring. Among these stations, Yantian International Container Terminal Station (YTG), Mawan Port Station (MWG), Shekou Ferry Terminal Station (SKMT), which are located close to seawater, have relatively smaller gust factor, compared to the factors at other stations. With the increase of the distance to the coastline, the gust factor at the stations becomes bigger. Therefore, the gale tends to be more instantaneous at the stations with farther distance to coastline than the gale at coastal stations. Among the eight stations, Beizaijiao Station (BZJ) and YTG have the most frequent gust gale records. The historical maximum gusts at the two stations are above 12 level scale (Beaufort scale), and the historical maximum 10 min average wind is above 9 level scale at BZJ and 10 level scale at YTG. Further case studies show that the gust gale in Shenzhen Area induced by severe convective weather is more instantaneous than those induced by typhoon or cold front. The location of the gust gale induced by severe convective weather is more stochastic. This study could provide references for the seasonal wind forecast and risk assessment in Shenzhen Area.
