Antarctic radar data improves forecasts for Southern Hemisphere atmospheric rivers in tests

Дата публикации: 28-09-2026 07:00:02

Weather forecasts in the Southern Hemisphere (SH) are generally less accurate than those in the Northern Hemisphere because Antarctica and the surrounding Southern Ocean have relatively few weather observations. With limited information about atmospheric conditions in one of the world's most remote regions, forecasting models often struggle to predict the movement of weather systems. This is especially true for atmospheric rivers that can trigger heavy rain, snowfall, flooding and strong winds across Australia, New Zealand, South America and Antarctica. Improving forecasts of these weather systems is essential for protecting lives and property, supporting aviation and shipping, and helping communities prepare for hazardous weather.
