The Southern Hemisphere is experiencing a rare but powerful stratospheric warming event that will have a global impact. These events are typically seen in the Northern Hemisphere and can disrupt the Polar Vortex, creating unusual weather patterns. The stratosphere, home to the ozone layer, is being influenced by high-pressure anomalies and warming waves, affecting the circulation over the southern hemisphere. The connection between the hemispheres shows that changes in the South Pole can impact the weather in the Northern Hemisphere. This recent warming event highlights the interconnectedness of global weather patterns and the potential for significant impacts on temperature anomalies and weather disruptions.
