【 摘 要 】

Extreme wind, thunderstorm, occurs throughout the world, even in the polar regions. At any given time approximately 2,000 thunderstorms are occurring on Earth. Many structural damages induced by them have been recorded around the world. Study of thunderstorm outflows and their effects on structures already becomes a key topic in modern wind engineering. This paper analysed the main properties of a typical thunderstorm outflow event occurred in Beijing based on the measured data detected by 9 ultrasonic anemometers mounted on the 325 m high Beijing meteorological tower. It is fundamental and crucial to learn the phenomena in urban area and study the structural response to thunderstorm outflows.
