Abstract

This study has examined the observed record of peak gust wind speed (daily maximum 3-second averaged gust wind speed) in order to establish the existence of bias between the early part of the record (measurements obtained using pressure-tube Dines anemometers) and the later part of the record (measurements obtained using cup anemometers). All observational data as well as metadata was obtained from the Bureau of Meteorology. The 38 recording stations considered were in the most part staffed by Bureau of Meteorology officers. To isolate the issue of anemometer replacement, only observing stations located at airports (i.e. those with consistent exposure) and with more than 30 years of record were considered. The visual inspection of the observed daily peak gust wind speed time-series for most of the Bureau of Meteorology observing sites considered in this study is sufficient to indicate that in general the early part of the observing record contains a higher frequency of extreme events, and also the largest amplitude extreme events. Statistical analysis of the daily maximum gust wind speed observations was conducted by employing extreme value distributions (EVD) to examine the difference between two datasets: (1) time-series of Dines & cup anemometer observations (no overlap for each station) (2) coincident Dines & cup anemometer observations
