Part 1. Reversal of a roller vortex chiral state in a well induced by a temporal modulation of activity. Left: experimental video of the system. Right: superimposed velocity (arrows) and vorticity (background colour) fields of the rollers during the chiral state reversal. The size of the wel...
The polar vortex is a large area of low pressure and cold air surrounding both of the Earth's poles. It ALWAYS exists near the poles, but weakens in summer and strengthens in winter. The term "vortex" refers tothe counter-clockwise flow of air that helps keep the colder air near the P...
Extreme polar vortex events known as sudden stratospheric warmings can influence surface winter weather conditions, but their timing is difficult to predict. Here, we examine factors that influence their occurrence, with a focus on their timing and verti
As a result, the depletion of the ozone layer inside the polar vortex over the entire winter was relatively small over the past 20 years. The other distinguishing feature of the 2010 winter was the splitting of the stratospheric polar vortex into two lobes in December. The vortex splitting ...
“Polar vortex” pattern at 18,000 ft altitude forecast to be centered near Charleston at noon, Saturday, Nov. 1, 2014. Luckily, the deepening low pressure off the coast is expected to stay offshore, with northerly winds at Cape Hatteras around 50 mph Saturday night: ...
FOR years, the Polar Bear has been abused by climate change activists as the poster child ofClimateChange™️. They didn’t use rats or spiders to promote their misanthropic agenda. Instead, they chose the cute, cuddly, fluffy polar bear to illicit a desired emotional response. ...
The linkage between the sea ice concentration(SIC)over the Barents–Kara Seas in November–December(SIC_BKS_ND)and the stratospheric polar vortex(SPV)in subsequent January(SPV_Jan)is investigated.It is found that SIC_BKS_ND is positively(negatively)correlated with SPV_Jan for the period 1979–...

(December 1987), the warm North Polar Stratospheric Vortex (NPSV) could already be seen11. The longevity of Cassini’s exploration of Saturn (2004–2017) now provides the first complete data set to trace the growth of the NPSV, as Saturn reached northern summer solstice (Ls = 90°)...
