Polar

In early winter, cold temperatures result in the formation of a strong
circumpolar flow in the stratosphere, known as the Polar Night Vortex,
producing favorable conditions for ozone depletion. |

Polar Vortex
High Resolution Simulation
This new simulation of the stratospheric polar night vortex breakdown
was computed at a significantly higher resolution than the previous
one (two to four times the horizontal and vertical resolution). |
