English

Subject field(s)
  • Meteorology
  • Radio Waves
DEF

The transmission of various forms of energy through the atmosphere when the energy is refracted to move along a path other than the line-of-sight path by density discontinuities at one or more levels in the atmosphere. It results from the unusual vertical profiles of temperature and moisture.

French

Domaine(s)
  • Météorologie
  • Ondes radioélectriques
DEF

Transmission de diverses formes d'énergie dans l'atmosphère quand l'énergie est réfractée vers une trajectoire autre que la trajectoire directe par les discontinuités de densité à un ou plusieurs niveaux de l'atmosphère. Elle résulte d'une distribution verticale inhabituelle de la température et de l'humidité.

Spanish

Campo(s) temático(s)
  • Meteorología
  • Ondas radioeléctricas
DEF

Transmisión de distintas formas de energía en la atmósfera cuando la energía se refracta hacia una trayectoria distinta de la trayectoria directa por discontinuidades de la densidad en uno o varios niveles de la atmósfera. Depende de una distribución vertical poco corriente de la temperatura y la humedad.
