AI Summary

Southern Hemisphere weather forecasts are less accurate than those in the Northern Hemisphere because Antarctica and the surrounding Southern Ocean have few weather observations. Limited data on atmospheric conditions in this remote region makes it hard for models to predict the movement of weather systems. This difficulty is especially pronounced for atmospheric rivers, which can bring heavy rain, snowfall, flooding, and strong winds to Australia, New Zealand, South America, and Antarctica. Better forecasts of these systems are essential for protecting lives and property, supporting aviation and shipping, and helping communities prepare for hazardous weather.
