Stratospheric Warming Event Over Southern Hemisphere and Potential Global Impacts
• A stratospheric warming event is unfolding over the Southern Hemisphere during its winter season, with potential global impacts, including effects on the upcoming Northern Hemisphere winter.
• These rare events, driven by the Polar Vortex, involve strong temperature and pressure waves in the stratosphere and can disrupt weather patterns.
• The upper and lower parts of the Polar Vortex are connected, and changes in the upper part can significantly impact weather anomalies in the lower atmosphere and at the surface.
• A new stratospheric warming event is being analyzed over the Southern Hemisphere, similar to those in the Northern Hemisphere, with the potential to intensify over time.
• The event is characterized by a rapid rise in pressure and temperature in the stratosphere, potentially collapsing the Polar Vortex and impacting weather patterns for weeks.
• The Southern Hemisphere event is expected to weaken the Polar Vortex, with a warming wave displacing the cold core and creating disrupted pressure patterns.
• The impacts of the Southern Hemisphere Stratospheric Warming event can reach the Northern Hemisphere, potentially influencing weather patterns and even the following winter season through the Brewer-Dobson circulation.
