Previous proposed mechanisms for the polar vortex response to climate change, based on analysis of atmosphere-only models, are found inadequate to explain the intermodel spread in the coupled models in CMIP5. It is further found that resolved stationary wave driving in the polar vortex region ...
adults and geocoded National Weather Service data, we examine how a range of extreme weather event categories relate to climate change beliefs, and the degree to which individuals' self-reported experiences are shaped by their political views across event types. For tornado, hurricane, and flood ...
Over the past few decades, due to human-caused climate change, the coldest extremes are getting less extreme. As one example, in Minneapolis the coldest day each year is now 12 degrees warmer than it used to be. CBS News Bitter cold air is only half of the concern. A parade of ...
A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.
Among the terms used to describe wintery weather, the most dreaded might be “polar vortex.” The ominous term sounds like some earthly black hole trying to kill us with Arctic air. So what exactly is a polar vortex, and why do we keep hearing about it year after year?
根据最后一段倒数第一、二句“But theNatiomal Weather Service said there was nothing new aboutit. It said the years 1977, 1982, 1985 and 1989 alsobrought unusually cold temperatures caused by a polarvortex.”可知,国家气象局表示这并不是什么新鲜事,而且列举了4年类似的寒冷天气,认为这没有那么罕见...
How does climate change affect the environment? How do changes in global temperature affect ocean acidification? How does the carbon cycle effect the Arctic Ocean? How is the polar vortex caused by global warming? How does a circumpolar current affect climate?
The possible influence of changes in the Arctic stratospheric polar vortex on the extratropical troposphere especially in the mid-to-high latitudes of the
The polar vortex first began to get wobbly in early January, after showing signs that it might split apart. These polar winds are always liable to get pushed around by fickle weather patterns, storms, or other disturbances that move around our atmosphere, Benjamin ...
If the influence of the weak polar vortex on CAO occurrence arises exclusively through an influence on the AO, then the response of CAOs in each region of the northern extratropics to the weak polar vortex should be proportional to the associated change in the AO index (Supplementary Fig. 7a...
