Programme overview

Wind shear refers to the change of wind vector (wind direction, wind speed) in the horizontal and vertical distances in the air. There are two main causes of wind shear. One is caused by changes in atmospheric motion itself, such as frontal motion, thunderstorms, weather and temperature inversion phenomena etc.; The other is caused by geographical and environmental factors, such as the influence of mountains, buildings and trees. Wind shear is called the "invisible air killer."

Since 2014, the lidar team of Ocean University of China has used coherent Doppler wind lidar to carry out low-level windshear observation and early warning. So far, the team has cooperated with Boeing (China) Co., Ltd. and the North China Air Traffic Management Bureau of Civil Aviation in many scientific research projects, including low-altitude windshear observation, windshear factor search, and high-precision three-dimensional wind field detection at the Capital Airport.
