Rare November Stratospheric Warming Event Threatens Winter Forecast
15 Nov
Summary
- Sudden stratospheric warming event may occur, disrupting polar vortex
- Relationship between polar vortex and La Niña pattern is complex
- Potential for extended period of colder and snowier weather starting in December
According to the latest weather reports, a rare and potentially disruptive event may be on the horizon for the upcoming winter season. Meteorologists have detected signs of a sudden stratospheric warming (SSW) event, which could significantly impact the behavior of the polar vortex and the overall winter forecast.
The stratosphere above the North Pole is showing signs of a dramatic warming, which could push the cold air from the north towards the United States. This type of SSW event is considered the largest disruption to the polar vortex and has only been observed twice in November before the satellite era.
The relationship between the polar vortex and the ongoing La Niña weather pattern is complex, and there is no clear winner between the two. However, the behavior of the polar vortex is expected to be more influential in determining the severity of the cold weather. If the stratospheric warming strongly influences the jet stream, it could lead to an extended period of colder and snowier conditions starting in December and potentially lasting into early January.
Meteorologists are closely monitoring the situation and warn that the upcoming winter could be significantly colder and snowier than usual if the SSW event occurs and the polar vortex is disrupted. However, if the stratospheric warming has a weaker influence on the weather patterns, the winter could remain relatively mild across the United States.
