Targeted observation and process-informed modelling of Antarctic sea ice (TOPIMASI)
Antarctic sea ice plays a major role in the global climate system. Its presence maintains cold conditions that help sustain Antarctica’s ice sheets, and it affects the rate of global warming by changing heat uptake in the Southern Ocean. Antarctic sea ice has a significant influence on both the ocean and atmospheric components of the climate system, and sea ice extent is closely linked with weather systems over New Zealand.
The region between Aotearoa New Zealand and Antarctica – the Southern Ocean – plays an important role in influencing New Zealand’s weather and climate.
A Phase 2 project: Producing climate simulations using the NZ Earth System Model, the NZ Regional Climate Model and the NZ Water Model
In a rapidly changing climate, this major project for New Zealand helps us take our future into our own hands. Our rounded approach to modelling – from the global to the local and specific – helps us understand how New Zealand’s climate has changed over the recent past and how it will change this century.
