Weather forecasting

Scaling up of solar and wind power is essential for Aotearoa New Zealand to become carbon neutral by 2050

NIWA and the Ministry for Primary Industries (MPI) are working together to develop a new drought forecasting tool.

NIWA’s research into forecasting weather systems aims to increase the resilience of New Zealand communities to weather-related hazards.

NIWA has produced a high-resolution regional atmospheric reanalysis dataset, the New Zealand Reanalysis (NZRA).

El Niño and La Niña are opposite phases of a naturally occurring global climate cycle known as the El Niño Southern Oscillation, or ENSO for short.

El Niño is on its way, with whispers it could cause the Earth’s warmest ever year. But what is it? NIWA scientists tell all.

Improvements in data and climate science mean forecasters are able to predict patterns much further ahead and in far greater detail. Melissa Bray looks at what this may mean for farmers.
