Statistical Characteristics of Gusty Wind Conditionally Sampled with an Array of Ultrasonic Anemometers
The present field experiment aims to clarify statistical characteristics of gusty winds having dimensions relatively smaller than their parent convective systems. Three wind velocity components were measured by using 12 ultrasonic anemometers aligned along the Dai-ni Mogami river bridge in Shonai plain, Japan. The gust events were conditionally sampled referring to steep triangle wave. The extracted events were more than 9000 and concentrated in winter season. We separated incidence per day to over 10 events per day and under 10 per day. Scale of gust events for over 10 per day was larger than the case of under 10 per day.
