To create the effect of wind on your TerrainThe landscape in your scene. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape. More info
See in Glossary, you can add one or more GameObjects with Wind Zone components. Trees within a wind zone bend in a realistic animated fashion, and the wind itself moves in pulses to create natural patterns of movement among the trees.
To create a Wind Zone GameObject directly, go to Unity’s top menu and go to GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary > 3D ObjectA 3D GameObject such as a cube, terrain or ragdoll. More info

The Main property determines the overall strength of the wind, and you can use Turbulence to give these some random variation.
The wind blows over the trees in pulses to create a more natural effect. You can control the strength of the pulses with Pulse Magnitude, and the time interval between them with Pulse Frequency.
The main use of wind is to animate trees, but it can also affect particles in a Particle System if that Particle System uses the External Forces module module. See the Particle SystemA component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene. More info
