Treatment of extreme surface winds

Key Points

This research aims to clarify the complexities of measuring and interpreting extreme wind gusts.
Evaluated data from various anemometers installed at key locations.
Discussed the impact of exposure variations on wind measurements.
Analyzed historical records of extreme winds, including notable gusts.
Identified difficulties in applying recorded data to different sites within the same climatic zone.
Concluded that consistent exposure of anemometers is crucial for accurate data interpretation.
Listed exceptional wind events, including tornadic squalls from southern Australia.

Abstract

Even though reliable anemometers have been installed at many key points the interpretation of extreme wind gust data is rendered difficult by the nature and variations of the exposure of the instrument in many cases and by the short period of record which makes reliable statistical treatment doubtful. The app11cability of recorded data to a different site is another uncertainty even within the same climatic zone. Furthermore, doubt is cast on the practice of adjusting extreme wind gust velocities to another height and it is concluded that constancy in exposure, provided it is reasonably good, is of prime importance. Gust structure is also discussed, with an example of a phenomenal wind at Lord howe Island, Whilst a few other exceptional winds are listed, notably some tornadic squalls experienced over southern Australia during the last three or four years.
