Wind Watch

Real time, reliable wind profiler

Wind Watch is a new-generation wind profiler, able to provide detailed and accurate information about winds to 400 meters.

The data Wind Watch makes available on wind direction and strength at altitude provides precise real time warnings of wind shear, increasing safety and reducing expensive go-arounds.

Unlike LIDAR-based wind profilers Wind Watch is not dependent on visibility and can ‘see through’ fog and inversion layers to report on wind conditions and hazards above them.

Importantly, Wind Watch meets ICAO update rate requirements of 2 minutes and is suitable for operational meteorological use.

Wind Watch is quick and easy to deploy as either a permanent or mobile trailer-based unit.

Sky Watch

Accurate and reliable atmospheric structure monitoring

Sky Watch provides an accurate profile of atmospheric structure up to an altitude of 800 meters.

Real-time information about the atmosphere is particularly important in maintaining safety, as inversion layers can result in long-lived wake turbulence at or about the height of the inversion.

Sky Watch, when used in conjunction with Wake Watch, can provide a very reliable predictor of wake behaviour, and therefore advance warning of potential wake turbulence issues

Sky Watch is quick and easy to deploy and has high availability to 400 meters. Above 400 meters, availability may be reduced in different weather conditions.

A straong gust front and wind direction change at Melbourne Airport on 4 January 2019. The instant wind direction and speed update every 15 seconds to 400m while the average is over 8 updates or 2 minutes. The standard deviation of the measured wind speed and direction after the change is also shown.

A strong temperature inversion layer is shown at Melbourne Airport between 16:30 and 17:30 UTC on January 28 2019. This inversion layer is strong enough to cause wake vortices to be very long lived and is a hazard to any aircraft following too closely behind. There is aslos some vertical wind shear through the inversion layer.

Strong temperature inversion layers on 6 May 2014 at Melbourne Airport. Aircraft wake vortices can be very long lived.
Later in the day on 6 May 2014, the sun heating of the surface causes strong convection which breaks up the inversion layers and provided much more turbulence in the atmosphere. In shuch circumstances, wake vortices are very short lived and the application of Minimum Radar Separation ( MRS ) can provide a significant increase in runway capacity.
