Wind
urn:aero:airm:1.0.0:LogicalModel:Subjects:Meteorology:Wind
Air motion relative to the Earth's surface. Unless otherwise specified, only the horizontal component is considered.
| Properties | Definition | Type |
|---|---|---|
| crosswind | A wind blowing perpendicularly to one's direction of travel or orientation. | ValSpeedType |
| windSpeed | The speed of the wind. | ValSpeedType |
| windGust | Variation from the mean surface wind speed as defined by ICAO Annex 3. | ValSpeedType |
| windDirection | Direction from which wind is blowing. |
Angle |
| verticalWindGust | Component wind gust in the upward or downward direction. | ValSpeedType |
| minWindSpeed | The minimum speed of the wind. | ValSpeedType |
| maxWindSpeed | The maximum speed of the wind. | ValSpeedType |
| isVariable | Indication that the direction of the wind changes frequently. According to Annex 3 the wind is reported as variable (VRB) in local routine or special reports, in METAR and SPECI, when one of the following situations occur: - when the total variation is 60 or more and less than 180 and the wind speed is less than 1.5 m/s (3 kt), the wind direction shall be reported as variable with no mean wind direction; or - when the total variation is 180 or more, the wind direction shall be reported as variable with no mean wind direction. |
Boolean |
| isCalm | Indication that the wind is forecast to be less than 0.5 m/s (1 kt). |
Boolean |
| headwind | A wind blowing from directly in front, opposing forward motion or orientation. | ValSpeedType |
| extremeCounterClockwiseWindDirection | The extreme counter-clockwise direction from which the wind is blowing, inclusive. |
Angle |
| extremeClockwiseWindDirection | The extreme clockwise direction from which the wind is blowing, inclusive. |
