摘要
利用深圳沿海站点的风速观测资料，按季风及热带气旋2种类型探讨了阵风和阵风系数的统计特征，结果表明，季风影响下，盐田港站和流花111平台站出现6—9级风的频率明显高于热带气旋型，在9级风以上，热带气旋型略偏高；妈湾港站的阵风系数随平均风变化稳定，而盐田港站和海上石油平台站受地形和下垫面影响，与妈湾港有显著差异；7级以上强风的频率日变化显示盐田港在夜间出现强风的概率显著增加。
Based on the wind -2014, the characteristics of gust analyzed. It shows that the frequen observation data of three factors, based on either meteorological stations of Shenzhen during 2009 the type of monsoons and tropical cyclones, are cy of wind force 6 to 9 was higher under the impact of monsoons while that of wind force 9 or above was more frequent with type of tropical cyclones. Gust factors are sensitive to 10 - minute mean wind as shown by different stations. Excessively higher nighttime gale frequencies at Yantiangang station need to be studied further.
