  • Atmospheric, Climatic and Meteorological Phenomena
CONT

Through the outer ring unsettled weather prevails. The sky is ordinarily covered with a light haze, which increases in density as the center of the storm approaches.

Record 5 2011-12-22

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
CONT

As the dry air is forced over the coastal range and descends from the high desert to the coast, it warms adiabatically and relative humidity falls even further, virtually eliminating the possibility of precipitation.

CONT

Weather is normally unsettled in the vicinity of a cyclone, with increased cloudiness, increased winds, increased temperatures, and upward motion in the atmosphere which leads to an increased chance of precipitation.... Under surface highs, sinking motion leads to skies that are clearer, winds that are lighter, and there is a reduced chance of precipitation.

Record 6 2006-03-18

English

Subject field(s)
  • Atmospheric Physics
DEF

An area of low pressure caused by very warm, dry air.

CONT

Heat lows or thermal troughs often build north along the coasts of California and Oregon in the summer. Thermal troughs can cause "east winds" in the Washington and Oregon Cascades. If however, a relatively strong disturbance in the upper atmosphere moves across the NW, it will force the thermal trough east of the Cascades. In most cases, a moderate to strong push of marine air will follow, along with strong, gusty, west winds along the east slopes of the Cascades. Gusty winds and thunderstorms can be associated with the passage of a thermal trough.

CONT

A front may have troughing along its length, but not all troughs are frontal! Indeed, not all troughs have ’weather’ associated with them in the cloud/rainfall sense. Lee troughs found downwind of a major range of hills/mountains are often cloudless, and thermal troughs forming over land during the day due to mesoscale heating may only be found by careful drawing of isobars: if the air is dry and/or stable, little significant cloud will be associated with this feature.

OBS

trough : A feature on a weather map where mean sea level pressure(or upper contour heights) are lower than surrounding areas of the atmosphere, with a ’V’ shape to the isobars/contours evident in the pattern. Often associated with unsettled/cloudy weather, but not always.

French

Domaine(s)
  • Physique de l'atmosphère
OBS

thalweg (s'écrit aussi talweg) - trough : Axe de basses pressions prolongeant une dépression. Les isobares sont en forme de V. Son passage est marqué par une brusque rotation du vent (grain).

OBS

talweg : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

Record 7 2004-05-13

English

Subject field(s)
  • Atmospheric Physics
DEF

... a swift-moving cold frontal passage in the southern Great Plains [of North America], marked by a dark, blue-black sky with strong wintery winds from the northwest or north and temperatures that may drop 20°F to 30°F in a few minutes.

OBS

The term "blue norther" is most commonly associated with Texas. Various other names for the same phenomenon exist over the central and southern Plains [California norther, etc. ]. There are also various theories as to the exact origin of the term. In general it is associated with a rapidly moving cold front(usually in the Autumn) that causes temperatures to drop quickly and that often brings with it precipitation and unsettled weather, followed by a period of blue skies and cold temperatures.

OBS

Some authors consider "blue norther" as a synonym of "Texas norther", others consider it as a related term. Compare to "Texas norther".

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Vent fort et froid, venant du nord, dans diverses parties de l'hémisphère Nord.

OBS

Le Grand dictionnaire encyclopédique Larousse répertorie «northern» au lieu de «norther». Norther figure dans les dictionnaires spécialisés de météorologie.

OBS

northern : Phénomène relevé en Amérique du Nord (centre et sud-est des États-Unis et occasionnellement golfe du Mexique), qui correspond à l'arrivée d'air polaire continental aux latitudes subtropicales, voire intertropicales.

OBS

Il ne semble pas y avoir de correspondance française pour le terme «blue norther». Aussi, le terme générique «norther» semble être le meilleur équivalent. Cependant, René Héroux, météorologue à Environnement Canada, suggère d'utiliser le terme anglais avec une note explicative sur la provenance de ce terme.
