The atmospheric pressure at mean sea level usually determined from the observed station pressure.  3, record 1, English, - mean%20sea%20level%20pressure

Record number: 1, Textual support number: 1 OBS

Mean sea level pressure is computed from the station pressure and reported so that the barometric pressures at stations of different elevations can be compared at a common level for analysis purposes.  3, record 1, English, - mean%20sea%20level%20pressure

Pression atmosphérique au niveau moyen de la mer, généralement déterminée à partir de la pression observée à la station.  2, record 1, French, - pression%20au%20niveau%20moyen%20de%20la%20mer

Record number: 1, Textual support number: 1 OBS

La pression au niveau moyen de la mer est calculée à partir de la pression à la station et est enregistrée, de manière à ce que les pressions barométriques à des stations d'altitudes différentes puissent être comparées à un niveau commun à des fins d'analyse.  2, record 1, French, - pression%20au%20niveau%20moyen%20de%20la%20mer

With regard to the Pacific side of the Arctic Basin, Overland et al. (1997) report that the position of the tropospheric cold pool is approximately centered over the Canadian Arctic and the Beaufort Sea, displaced from the North Pole by orographic effects of the North American mountain ranges. The result is advection of atmospheric heat and moisture into the Greenland and Barents seas, and the eastern Arctic. The position of this arctic cold pool in turn affects the position of the arctic front and the atmospheric circulation in the western Pacific.  1, record 2, English, - arctic%20cold%20pool

There are at least three distinct types of cold pool : 1. Large(in areal extent), slow-moving vortices at latitudes poleward of roughly 50deg N & S. They are often over, or immediately downwind of the source regions of polar or arctic air masses, in such areas as the Canadian Arctic or Siberian Russia. They take up the characteristics of quasi-permanent features, often appearing on monthly, or even seasonal average maps. The column of very cold(dense) air associated with this version of the cold pool, is reinforced by net outgoing radiation which produces a highly stable, bitterly cold near-surface environment, with a surface ridge or anticyclone on MSLP charts. 2. Once cold air from the source region as detailed in(1.) above is caught up in the circulation of mid-latitude depressions, the characteristics of the air mass are altered... 3. A pool of cold air can also become "detached" at lower latitudes...  2, record 2, English, - arctic%20cold%20pool

En 1992, deux auteurs anglais, Price et Vaughan, publièrent une étude statistique des gouttes froides, en séparant 3 types : les gouttes froides de type arctique, de type polaire et de type subtropicale, en fonction du courant-jet au voisinage duquel eut lieu le détachement stratosphérique.  1, record 2, French, - goutte%20froide
