Record number: 1, Textual support number: 1 OBS
The westerly airflow is largely a manifestation of the thermal wind above the polar frontal zone of middle and subpolar latitudes. The vortex is strongest in winter when the pole-to-equator temperature gradient is strongest. In the Northern Hemisphere, the vortex has two centers in the mean, one near Baffin Island and the other over northeast Siberia. 5, record 1, English, - polar%20vortex

Le phénomène du trou d'ozone est renforcé par l'existence de ce que l'on nomme le vortex polaire, un modèle de circulation particulier à la stratosphère au-dessus du pôle sud au cours de l'hiver austral et qui isole cette région de son environnement [...] 4, record 1, French, - tourbillon%20circumpolaire

El vórtice polar austral es más fuerte que el septentrional. El vórtice aumenta el agotamiento del ozono al retener aire muy frío que contiene aerosoles y en el cual pueden tener lugar las reacciones de destrucción del ozono. 3, record 1, Spanish, - v%C3%B3rtice%20polar

Al fenómeno que azota EE.UU. [Estados Unidos] se lo denomina “vórtice polar”. Es un sistema de baja presión profunda que se extiende a los niveles superiores de la atmósfera y hace descender masas heladas de aire que, por lo general, circulan alrededor del Círculo Polar Ártico. 4, record 1, Spanish, - v%C3%B3rtice%20polar
