Record 1 2023-02-22

English

Subject field(s)
  • Electromagnetic Radiation
  • Environmental Management
  • Climate Change
CONT

Solar radiation modification refers to the intentional modification of the Earth’s shortwave radiative budget with the aim of reducing warming.

OBS

Artificial injection of stratospheric aerosols, marine cloud brightening and land surface albedo modification are examples of proposed SRM methods.

French

Domaine(s)
  • Rayonnements électromagnétiques
  • Gestion environnementale
  • Changements climatiques
DEF

Modification volontaire du bilan radiatif «ondes courtes» de la Terre visant à réduire le réchauffement climatique.

OBS

L'introduction artificielle d'aérosols dans la stratosphère, l'augmentation du pouvoir réfléchissant des nuages au-dessus de l'océan ou l'altération de l'albédo des terres émergées sont des exemples de techniques de modification du rayonnement solaire envisagées.

Record 2 2004-11-26

English

Subject field(s)
  • Climatology
DEF

Intentional or unintentional change in the weather caused by human activities.

OBS

weather modification(weather control). The term usually refers to cloud seeding activities, but can also include constructing windbreaks, dissipating fog by the forceful addition of heat or water spray, or preventing frost formation on crops by cloud spray, heating, or mixing processes. Inadvertent weather modification refers to accidental weather effects resulting from the release of greenhouse gases, aerosols, and dust, or changes in albedo or surface properties of the earth associated with urban, industrial, or agricultural activity.

OBS

Schemes for modifying the long-range climate of a region are often referred to as climate control.

OBS

In some sources, "weather control" is considered as a synonym of "weather modification" whereas in the International Glossary of Meteorology (OMMV) it has a separate entry and it is defined as a "Weather modification carried out towards a deliberate end."

Key term(s)
  • weather artificial control
  • modification of the weather
  • control of the weather

French

Domaine(s)
  • Climatologie
DEF

Changement, intentionnel ou non, du temps imputable à l'activité humaine.

CONT

La modification des conditions météorologiques observée ces jours-là ne permet pas de faire toute la lumière sur cette alerte à la pollution atmosphérique ni sur l'efficacité réelle des mesures de circulation adoptées.

OBS

Le Glossaire international de météorologie définit le terme «modification artificielle du temps» comme étant une «Modification du temps faite dans un but déterminé.»

Spanish

Campo(s) temático(s)
  • Climatología
DEF

Modificación del tiempo causada por actividades del hombre, sean éstas intencionales o no.

Record 3 2004-10-12

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
DEF

A pyrotechnic device used in weather modification or cloud seeding to produce a controlled release of seeding agent from an aircraft.

CONT

pyrotechnic flare: Equipment for delivering silver iodide particles from an aircraft. There are two types: the trailing flare and the dropping flare.

French

Domaine(s)
  • Stations, instruments et équipements météorologiques
DEF

Pièce pyrotechnique aéroportée à extrémité combustible qui permet un contrôle amélioré et graduel de l'ensemencement des nuages.

OBS

[La] fusée pyrotechnique [...] sert à la dispersion d'iodure d'argent à partir d'un aéronef. Il y en a deux types : l'une est attachée à l'aéronef, l'autre tombe en chute libre.

Spanish

Campo(s) temático(s)
  • Estaciones, instrumentos y equipos meteorológicos
OBS

Dispositivo de extremo combustible, análogo a un cohete de aviso, utilizado por una aeronave para alcanzar una siembra más controlada y gradual de las nubes.

OBS

cohete pirotécnico: Equipo de dispersión de partículas de yoduro de plata desde una aeronave. Existen dos tipos: cohete fijado a una aeronave y cohete de caída libre.

Record 4 1999-03-16

English

Subject field(s)
  • Air Pollution
  • Pollutants
  • Climatology
CONT

The influences of chemical wastes on weather and climate could be greatly amplified when they affect clouds. The presence or absence of clouds and their nature can have dramatic effects, as can small changes in their frequency or placement; therefore, changes in clouds produced by aerosols generate enormous relative differences per unit of aerosol mass. Consequently, control attention should be directed especially to a chemical' s prospective effects on cloud modification and aerosol dynamics.

French

Domaine(s)
  • Pollution de l'air
  • Agents de pollution
  • Climatologie
CONT

Les sujets pertinents aux aérosols comprennent l'interaction des aérosols avec les produits chimiques de l'atmosphère et avec les radiations électromagnétiques, la dynamique des aérosols, ainsi que les natures physiques et chimiques des fumées d'écrans, des agents chimiques, des poussières et des émanations, des agents biologiques, des retombées des détonations des armements nucléaires et, finalement, le relâchement des aérosols radioactifs lors d'accidents de réacteurs nucléaires.
