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

Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. They are used for a variety of purposes from study of the dynamics of the weather and climate system to projections of future climate. The most talked-about models of recent years have been those relating air temperature to emissions of carbon dioxide ...

Le développement récent d’ordinateurs très puissants a rendu possibles l'étude et même la prévision de l'évolution générale du climat mondial à l'aide de modèles numériques de simulation de l'atmosphère. Ainsi, un modèle climatique se présente comme une adaptation spécifique d’un modèle numérique de prévision météorologique : il n’ a plus pour but la prévision opérationnelle à court terme ou moyen terme, mais l'étude des facteurs susceptibles d’influer sur le comportement du climat et, consécutivement, la simulation des changements de ce dernier sur des périodes pouvant aller de plusieurs mois à plusieurs décennies. De cette manière peuvent être abordés, entre autres, des processus environnementaux de dimension planétaire tels que les variations de l'oscillation australe, l'accroissement de l'effet de serre ou l'évolution du trou d’ozone stratosphérique. 4, record 3, French, - mod%C3%A8le%20climatique

Record number: 10, Textual support number: 1 CONT
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 10, English, - Antarctic%20ozone%20hole
