A pool of cold air can also become 'detached' at lower latitudes, i.e. away from the mid-latitude westerly zone, and drift slowly over relatively warmer seas, (e.g. the Mediterranean), and lead to intense convective development, often taking on marked cyclonic characteristics through the troposphere, and giving rise to locally severe conditions due to heavy rainfall, severe thunderstorms and squally winds. Remnants of these types of cold pool will sometimes drift polewards in summer and bring outbreaks of severe convective activity to mid-latitude regions, as these features will destabilise hot/humid air masses. 2, record 1, English, - cold%20air%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. Ces auteurs montrèrent que les gouttes froides de type subtropical sont plus petite, et durent moins longtemps, que les gouttes froides qui se forment aux latitudes moyennes et polaires. Ils en déduisirent que les gouttes froides de type subtropical n'engendrent pas d'échange stratosphère troposphère d'une manière significative. 3, record 1, French, - goutte%20d%27air%20froid

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. ... 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. Warming from below (over relatively warmer sea surfaces for example), leads to instability developing, and with an accompanying injection of moisture (after a reasonable length of passage over the sea), cloudy convection (showers, thunderstorms) is triggered. Cold pools in these situations are often maxima of such activity, with surface charts showing west or northwesterly airflow, often with cyclonically curved isobars. The cold pool will move in the general synoptic flow, and will eventually warm out (disappear) due to sensible & latent heat exchanges within the environment of the cold pool. However, ... sometimes the cold pool will transform into a slow-moving, longer-lasting entity, particularly if the feed of ex-polar air on its western flank is maintained - this occurs in highly meridional situations. 3. A pool of cold air can also become 'detached' at lower latitudes ... 2, record 2, English, - cold%20air%20pool

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 3, 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.
