    Abstract

    Wind speeds during the tropical cyclones that affected Suva, Fiji, during the last six cyclone seasons are statistically analysed. Since 2012, there were at least 13 cyclones that affected Suva. The wind data were recorded for the six cyclones seasons from October 2012 to April 2018. NRG#40C cup anemometers with a data-logger were used to record the wind speeds at 34 m and 20 m above ground level (AGL) for the above duration. The main investigation of these cyclones’ wind characteristics was based on the determination of turbulence intensity (TI), gust factor and the peak factor. The turbulence characteristics were then compared with the AS-NZ-1170.2-2002 standard and the peak factors were compared with the ISO standards. Detailed studies were carried out for the two strongest cyclones: Cyclone Evan and cyclone Winston, during which the 10-minute-averaged maximum wind speed exceeded 25 m/s at 34 m AGL.
