Drought forecasting dashboard
NIWA and MPI are working together to develop a new drought forecasting tool. It uses innovative climate modelling, the latest in machine learning and other data-driven techniques to predict rainfall 35 days ahead. It will help farmers and growers better prepare for periods of dryness and drought.
Climate and weather
-
What is the greenhouse effect?
Education ResourceThe greenhouse effect is a warming of the earth's surface and lower atmosphere caused by substances which let the sun's energy through to the ground but impede the passage of energy from the earth back into space. -
Definitions of drought
There are several definitions of drought, depending upon whether it is viewed as a hazard or a risk. -
Marlborough
The main characteristic of the Marlborough climate is its dryness. Summer droughts are frequent, and the region is often swept by warm, dry northwesterlies. -
Special Climate Statement 2017-18 Summer
Sea surface temperatures in the southern Tasman Sea rose to exceptionally high levels in late 2017 and early 2018. These temperatures were far above any others previously observed at that time of year in the region, and extended west from New Zealand to Tasmania and mainland southeast Australia. -
Mean number of days of ground frost
These datasets are available in a range of formats. -
UVI forecast for Specific Sites

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. -

Decision-Making Framework
A decision framework has been developed that provides for a balanced and justifiable prioritisation of sustainable adaptations to climate change and which is flexible to change.
