What Does 'maximum Sustained Winds' Mean? How Does It Relate To Wind Gusts In Tropical Cyclones?
The Bureau of Meteorology uses a 10 minute averaging time for reporting the sustained (i.e. relatively long-lasting) winds. The maximum sustained wind are the highest 10 minute surface winds occurring within the circulation of the cyclone. These surface winds are those observed (or, more often, estimated) to occur at the standard meteorological height of 10 m having an unobstructed exposure. Gusts are a wind peak lasting for just a few seconds. Typically, in a cyclone environment the value for a peak gust is about 25 % higher than a 10 minute sustained wind. Barrow Island and Mardie sustained wind and wind gust profile during TC Monty (2004).
