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. -
Winter 2020 – NZ’s warmest winter on record

HIRDSv4 Usage
NIWA'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. -
Native forests absorbing more carbon dioxide
Media release06 June 2017New Zealand’s forests and other land areas may be absorbing up to 60% more carbon dioxide than has been calculated, with much of this uptake likely occurring in native forests, NIWA scientists have discovered. -

What is Ocean acidification?
NIWA oceanographer Dr Cliff Law explains the impacts of ocean acidification on organisms that use carbonates to build their shells, and on bacteria. -
Assessment of crop and tree species growing potential using climate, soil and topographic information
Research ProjectThis project demonstrates how to assess high value alternative land-use options by means of a quantitative analysis of the growing potential of selected niche crops and tree species. -
Wave hazard research
Research ProjectNIWA collects wave data, develops and verifies wave forecasting systems, and is developing and producing wave projections.
