What Arctic Warming Means for Fall Weather in the U.S.
• Arctic warming weakens the jet stream, leading to more persistent and extreme fall weather patterns in the U.S.
• A weaker polar vortex can send frigid air masses southward, causing sudden and intense cold outbreaks.
• Climate models predict an increase in extreme weather events, unpredictable patterns, and longer-lasting weather systems in the U.S.
Arctic warming's impact on U.S. fall weather
The Arctic is warming at an alarming rate, twice as fast as the global average. This phenomenon, known as Arctic amplification, has far-reaching consequences, particularly for fall weather patterns in the United States. Understanding these impacts is crucial for preparedness and mitigation.
