English

Subject field(s)
  • Climate Change

Key term(s)
  • equivalent concentration of carbon dioxide
  • equivalent CO2 concentration

CONT

Les scénarios tendanciels convergent vers un doublement de la concentration équivalente de CO2 dans les années 2025-2030 en l'absence de toute action sur les autres constituants.

Record 4 2020-07-22

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Effects of Pollution
  • Climate Change
DEF

A climate feedback involving changes in the Earth’s surface albedo.

CONT

Values of warming for equilibrium CO2 doubling greater than 4 °C are suggested by two recently published studies and by some [global climate modeling(GCM) ] studies yet unpublished which were not available to previous assessments. These studies indicate that either large positive cloud feedbacks or, alternatively, large ice-albedo feedbacks and modest positive cloud feedbacks can give warmings of at least 4 °C. The possibility cannot be excluded that both large positive cloud feedback and large ice-albedo feedback might be realized.

French

Domaine(s)
  • Mesures et analyse (Sciences)
  • Effets de la pollution
  • Changements climatiques
DEF

Rétroaction climatique entraînant des changements dans l'albédo de la surface terrestre.

CONT

La glace de mer joue aussi un rôle important dans le système climatique [...] En hiver, elle isole l'océan de l'atmosphère froide; en été, elle augmente l'albédo (le pouvoir réfléchissant) au-delà de celui des eaux libres de l'océan. Donc, une augmentation de la quantité de glace diminue la quantité de rayonnement solaire absorbé et la température de surface, et augmente la formation de glace. L'inverse est vrai et entraîne une diminution du manteau de glace. La réaction, appelée rétroaction glace-albédo, est positive puisqu'elle renforce la perturbation initiale.

Record 5 2015-03-24

English

Subject field(s)
  • Oil Drilling
DEF

A drilling mud with entrained formation gas that gives the mud a characteristic fluffy texture.

OBS

Because the presence of a large amount of gas in the mud lowers its density, such mud requires treatment to avoid the danger of a blowout. However, since a small volume of gas expands as it reaches the surface, often it needs not be of concern.

OBS

GCM :... the abbreviation for gas-cut mud; used in drilling reports.

Record 6 2008-05-30

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Modelling (Mathematics)
DEF

A computer program that is used by atmospheric scientists to study and predict world-wide trends in weather patterns and the forces and physical laws that affect climate.

OBS

The formulae are complicated and require skilled mathematicians, atmospheric scientists, and powerful computers for execution. Five regimes that influence climate are often taken into consideration: atmosphere, hydrosphere, biosphere, cryosphere, and pedosphere. Atmospheric and environmental physical laws as well as principles of thermodynamics and hydrodynamics are all used as part of the extensive mathematical parameters for the program. The results of these models are used as reference for other models, policy decisions, and by meteorologists.

OBS

GCM :[The Atmospheric Radiation Measurement(ARM) Program Web site indicates that the] acronym is no longer used.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Modélisation (Mathématique)
CONT

[...] les modèles climatiques sont d'énormes logiciels qui simulent le fonctionnement de notre système climatique mondial en trois dimensions spatiales et dans le temps. Les modèles climatiques sont fondés sur les lois de la physique qui régissent la façon dont interagissent la matière et l'énergie. [...] Alors que les premiers modèles climatiques ne représentaient que les processus atmosphériques, les modèles «couplés» d'aujourd'hui reconnaissent que notre système climatique implique une myriade d'interactions complexes reliant l'atmosphère, les océans, les terres émergées et les masses glaciaires polaires. [...] Le modèle climatique mondial du Canada compte deux composantes principales : un modèle de circulation générale atmosphérique et un modèle de circulation océanique.

CONT

Les modèles climatiques mondiaux sont les seuls outils disponibles pour voir dans l'avenir et prévoir comment les régimes climatiques et les courants océaniques réagiront aux changements des gaz à effet de serre et des polluants connexes dans l'atmosphère.

OBS

global : En français, le terme «global» signifie «qui est considéré en bloc, dans sa totalité».

Subject field(s)
  • Meteorology
  • Scientific Measurements and Analyses
CONT

Impact studies have also created a growing demand for climate scenarios with a high temporal resolution, i. e. for information at the daily, or shorter, time scale. Moving from the global to the regional scale, and from the annual to the monthly and ultimately the daily scale, confidence in the reliability of GCM output tends to diminish...

English

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

Representation of the physical and dynamical processes associated with clouds.

CONT

There are several serious difficulties in including clouds in models. First, cloud properties are largely subgrid-scale. Even the most regular layered cloud systems have wide variations on a 100-km scale, and boundary-layer cumulus clouds can be of a scale less than 1 km.... Second, there is a wide variety of cloud types, each of whose radiative properties varies widely from cloud system to cloud system.... The third, and perhaps most serious difficulty, is that processes of cloud formation and cloud radiative properties have not been satisfactorily related observationally to other meteorological processes.... As a consequence of the limitations discussed above, the current approach of modellers is to make up some "cloud model" based on simple physical arguments, include this parameterization in a GCM simulation, and compare the resulting model cloud climatology with one or several observational climatologies.
