Generating synthetic wind data
Research ProjectNIWA has recently created synthetic, multi-year, 10-minute wind datasets at 15 wind farm sites across New Zealand. These will be used by the Electricity Commission to model the impact of wind farms on the national grid. -
Extreme weather - winds and tornadoes
Education ResourceDue to its position in the 'Roaring Forties', a belt of strong winds in the Southern Hemisphere which generally occur between the latitudes of 40 and 49 degrees, as well as its small size, New Zealand is a windy country. -
HIRDSv4 Usage
ESNZ's High Intensity Rainfall Design System (HIRDS) offers planners and engineers more certainty about the frequency of high-intensity rainfall events, enabling them to better design stormwater drainage, flood defence systems and other vital structures. -
