Record 1 2013-06-18

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

An unusually high rate of precipitation, generally rain, over a given period of time.

CONT

Periods of excessive precipitation can cause ground-water levels to rise, contributing a larger ground-water component to streamflow and causing changes in streamwater chemistry.

CONT

Still, there were areas of Canada which had above-normal precipitation: the Arctic islands, northern Quebec, Newfoundland, and small areas of southern Ontario and Quebec.

CONT

The annual precipitation varies primarily with longitude, with precipitation in excess of 2.5m at the coast, >1m in the inland valleys, >2m in the Cascades, and typically <0.5m to the east of the Cascades.

OBS

Excessive precipitation [is a] Standard U.S. Weather Bureau term for "rainfall in which the rate of fall is greater than certain adopted limits, chosen with regard to the normal precipitation (excluding snow) of a given place or area."

OBS

Precipitation: Any or all of the forms of water particles, whether liquid (e.g. rain, drizzle) or solid (e.g. hail, snow), that fall from a cloud or group of clouds and reach the ground.

OBS

Not the same as "excess rainfall" [or "excess precipitation"].

Key term(s)

DEF

Précipitation inhabituellement élevée.

CONT

La saison des pluies, qui a débuté en décembre en Bolivie, s'est intensifiée ces deux derniers mois. Les précipitations supérieures à la moyenne et les conditions de sécheresse antérieures ont entraîné des inondations et des glissements de terrain dans certaines régions du pays.

CONT

[...] certaines régions du Canada ont enregistré des précipitations supérieures à la normale : les îles Arctiques, le nord du Québec, Terre-Neuve et de petites zones du sud de l'Ontario et du Québec.

OBS

Les pluviomètres recueillent indifféremment toute l'eau atmosphérique sous ses divers états (brouillards, averses, neiges, etc.). Le total, mesuré par la tranche en millimètres, porte le nom de «précipitation».
