“we’re not used to it here, and we’re just not prepared,” grayson said. the polar vortex of ultra-cold air usually spins around the north pole, but it sometimes plunges south into the u.s., europe and asia. some experts say such cold air outbreaks are happening more fre...
Polar vortices were noticed long ago. But the first known use of the term “polar vortex” was in a magazine in 1853. Polar vortices are present year-round, but we don’t hear about them until they cause problems. They maintain freezing temperatures at the North and South poles by moving...
In doing so, we answer three important questions: (i) How are the t2g and eg orbitals affected by the local polarization and tetragonality? (ii) How does the rotation of the Ti 3d-orbitals affect the local crystal field? and, (iii) What is the crystal field at the vortex core, a ...
But for a huge swath of more populated land, from Alberta to Quebec in Canada, and the Pacific Northwest to the Northeast in the U.S., a polar vortex-linked series of frigid blasts await. SEE ALSO: The Weather Channel shuts down Breitbart: Yes, climate change is real The forecast ...
And during each dark winter, the Arctic's polar vortex — strong winds that circle westward around the pole — comes to life in the stratosphere. It's a normal, reoccurring winter phenomenon. "Every year we get this big spin up and then it disappears," marveled Andrea Lang, an atmospheric...
November. These modes are primarily wave-1 driven, generating tropospheric responses via negative Arctic Oscillation patterns. Conversely, the February and Dynamical modes show opposite signals, with Aleutian blocking and Ural trough events preceding strong polar vortex events. In December, the February ...
