| Field | Type | Required | Default | Allowed values | Description |

speedMps | number | no | Steady wind speed, m/s, 0..100. Default 0 (still air). Outside is clamped (air-out-of-range). | ||
directionRad | number | no | 0 | Compass bearing the wind blows toward, radians, as sky.clouds.windDirectionRad: 0 toward -Z, increasing toward +X. Default 0. | |
gustMps | number | no | Peak extra speed of a gust along the wind, m/s, 0..50. Default 0 (steady). Gusts are three waves of extra speed at fixed, seeded phases that travel downwind at the mean speed. Outside is clamped (air-out-of-range). | ||
gustPeriodS | number | no | 8 | Period of the longest gust wave, seconds, 1..120. Default 8. Outside is clamped (air-out-of-range). | |
seed | number | no | 1 | A whole number, 0 or more, that places the gusts. Default 1. |
