This dataset measures the strength of extreme wind at 30 sites across Aotearoa New Zealand from 1980 to 2022. For individual sites, we provide data for the highest maximum wind gust, average maximum wind gust, and the number of days with wind gusts extreme for a location. The average of the daily maximum wind gust provides information on windiness, while the maximum wind gust provides information on the strength of extreme wind events. The number of days with a maximum wind gust that exceeds the 99th percentile daily maximum wind gust speed, which measures how often extreme wind events (measured as a gust that is extreme for that location) occur for a site.
Variables:
site: NIWA climate site.
statistic: Highest max gust is maximum wind speed recorded, average max gust is monthly average calculated from highest 10min daily average, days above p99 is number of days above the 99th percentile calculated for all available daily data for each site.
month: Month representing data value. A month needed 100% of daily values to be calculated.
year: Year representing data value.
data_value: Calculated wind speed per given month and statistic.
lat: Approx. latitude location of NIWA climate stations to represent a site.
lon: Approx. longitude location of NIWA climate stations to represent a site.
unit: Unit of data value (recorded wind speed or days above 99th percentile).
