That arctic blast hitting the US? There's a wavy jet stream to blame.
— a ribbon of fast-moving air that flows over the Northern Hemisphere — is to blame for an Arctic onslaught that is blasting most of the United States with snow and record-low temperatures this week.National Weather Service forecasting
that an uncommonly large area could see record-low temperatures Wednesday, including most of the East Coast and from the Midwest south to the upper Texas coast. This week’s wintry blast, like all weather events, is the result of a complex interplay between atmospheric conditions and the movement of air around the planet. The frigid conditions across much of the U.S.
The jet stream, which flows west to east in the upper atmosphere over the Northern Hemisphere, is driven by temperature differences between the cooler polar region to the north and warmer air masses to the south. As this river of air circles the planet, it can undulate and create larger-than-normal peaks and troughs that impact weather systems. When the jet stream dips south and creates a trough, this allows cold, polar air to funnel southward. Conversely, when the jet stream swells into a peak, warmer air rushes in to fill that void and drier conditions typically prevail.Sign Up
