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

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

An "unexpected missing factor" may have surfaced in 1976 when the presence of trace levels of chlorine nitrate were detected in the stratosphere. The minor natural sink for ozone may furnish a way of scavenging the chlorine atoms generated from Freons, thereby reducing their effect on the ozone layer. 3, record 2, English, - chlorine%20nitrate

On croit que le chlore, un destructeur d’ozone, est stocké sous forme de nitrate de chlore, un élément important des nuages glacés polaires; au printemps austral(octobre), tout le chlore libéré sous l'effet du soleil entre subitement en action et ce phénomène serait à l'origine du trou d’ozone. La dissociation du nitrate de chlore libère les deux types de substances les plus destructrices pour l'ozone : le chlore et les oxydes d’azote. 2, record 2, French, - nitrate%20de%20chlore

Antarctic ozone hole ... The extremely cold temperatures within the polar vortex lead to formation of polar stratospheric clouds (PSCs) over large areas in early winter. These clouds are the key to the severe ozone depletion which has become known as the ozone "hole". PSCs form at the lower, colder altitudes (10-25 kilometres). The clouds are a major factor in causing large total column ozone depletion in the springtime Antarctic stratosphere. 4, record 4, English, - Antarctic%20ozone%20hole
