The geopotential method yields 1.3time higher vortex area for the Arctic and 1.14-time higher for Antarctica than the PV method. The estimates of the average wind speed at the vortex edge are very close: the wind speed by PV method is 5% higher than by the geopotential method for the ...
NASA's Solar Dynamics Observatory captured an unprecedented solar phenomenon on February 2 when a massive bright filament of plasma broke off the sun's surface, forming a whirlpool swirling around the sun's northern pole. "Talk about Polar Vortex!" the video clip was first shared b...

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...
It is expected that a convection vortex induced by downward FAC should be observed in the post-noon sector. The dusk side polar ionospheric convection pattern is shown in Figure 6 as a large-scale clockwise cell before the arrival of the IP shock. In the immediate aftermath of the SI onset...
After vortex to dissolve sample, the mixture was stood for a while for the separation of layers, 550 μL of water layer was mixed with 50 μL of internal standard (DSS) (0.001 g/100 μL) and then transferred to 5 mm of NMR tube, and 600 μL from the CDCL3 layer was to another...
The possible influence of changes in the Arctic stratospheric polar vortex on the extratropical troposphere especially in the mid-to-high latitudes of the Northern Hemisphere is still not well understood. Using the ERA5 reanalysis and based on the k-mean clustering algorithm, the northern winter str...
