Record 3 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.»

... of the World Meteorological Organization. The main purpose of the Programme is to stimulate collaboration and participation in basic research in the physics and chemistry of clouds and encourage application of this research with particular emphasis on the needs of weather prediction, weather modification and atmospheric pollution. This includes parameterization of clouds and precipitation processes in atmospheric models, the role of clouds in the radiative balance of the atmosphere, chemical transformation and transportation of pollutants, weather modification, etc. The programme provides information on the rationale underlying all aspects of weather modification and the role of clouds in atmospheric chemistry. It strives to identify uncertainties that inhibit progress and to encourage activities that contribute to their resolution.
