Wind shear refers to the change of wind vector (wind direction and wind speed) over horizontal and vertical distances in the atmosphere. The causes of wind shear can be broadly classified into two categories: one is due to changes in atmospheric motion itself, such as frontal movements, thunderstorms, and temperature inversion phenomena; the other is caused by geographical and environmental factors, such as the influence of mountains, buildings, and trees. Low-level wind shear, often referred to as the "invisible killer" in the air, significantly impacts the safety of aircraft during takeoff and landing.
Different observation modes are employed based on the terrain and wind field conditions of each airport, to detect variations in wind speed and direction. This enables the detection and early warning of wind shear, as well as the fine analysis of the wind field. The scanning modes include glide slope scanning mode, PPI scanning mode, and others.
Diverse data products, enabling synchronous inversion of radial wind speed, horizontal and vertical wind speed and direction, reverse wind profiles, wind shear intensity, and location products.
Wind shear observation experiments and applications have been conducted at multiple large airports in China, resulting in the establishment of a comprehensive wind shear monitoring and early warning system.
The software implements multi-parameter visualization with a clean and intuitive interface, effectively supporting airport management and control services.
