Atmospheric analysis

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.

We sponsor regional science and technology fairs around New Zealand and support learning programmes that bring science into the classroom.

These datasets are available in a range of formats.

The climate of this zone is largely dependent on the lie of the Southern Alps to the west, but many areas are also sheltered by high country to the south and east.

We recognise that there's so much more to life than just work!

Due 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.

Presented papers, arranged by workshop programme.

Up-to-date drought indicator maps are shown here.

The New Zealand Drought Monitor is a system for keeping track of drought conditions across New Zealand based on a standardised climate index.

New Zealand’s coast is sculpted by ocean waves. Some wave conditions bring joy to surfers and beachgoers, but, at other times, waves can cause major hazards at sea or along the shore.

A versatile inshore vessel, RV Ikatere is equipped with high-precision multibeam and sub-bottom profiler transducers for surveying and mapping the seabed.
