Predicting weather in the Southern Hemisphere is challenging. Here's why

Predicting weather in the Southern Hemisphere is challenging. Here's why

Weather forecasts in the Southern Hemisphere can be less accurate compared to the Northern Hemisphere. Despite advances in technology, there are still some gaps.

It's not easy to forecast the weather in the Southern Hemisphere.

Atmospheric scientists such as Kimberley Reid from the University of Melbourne face a number of unique challenges that make observing weather trickier here than in the Northern Hemisphere.

"The Northern Hemisphere has … so much more land mass. There's more people and more funding for observations, and more major cities," Dr Reid said.

"In the Southern Hemisphere … we don't have as many surface observations, or as many weather balloons, which are all necessary for working out what's going on."

Despite this, in recent years the Southern Hemisphere has narrowed the forecasting gap, with accuracy that almost matches our northern counterparts.

This isn't due to extra weather stations or balloons but rather an increase in data provided by international satellites, according to the Bureau of Meteorology (BOM).

While this has provided a wealth of data for weather forecasting around the world, experts warn that satellites can't help forecast everything.

And as weather gets more extreme, forecasters are turning to new technologies and techniques to keep up.

Humans have been trying to predict the weather for thousands of years, but it's only in the last few decades that forecasters could peer into the future with any kind of certainty.
