EQUATORIAL LATITUDES [4 records]

Record 1 2013-11-14

English

Subject field(s)
  • Atmospheric Physics
DEF

Mass of air which has been over regions close to the equator for several days and which, therefore, has become fairly warm.

CONT

Air masses are classified as equatorial if they develop near the equator, tropical if they originate in the low latitudes, and polar if they originate in the high latitudes. Equatorial air masses are warm and very moist, tropical air masses are warm, and polar air masses are... well, cold.

CONT

Equatorial (E) air masses, [hot and extremely humid], rarely visit the contiguous United States and almost never reach Canada, but these air masses are important weather factors for the southern nations of North America: southern Mexico, Central America and many of the Atlantic island nations.

Key term(s)
  • equatorial airmass
  • equatorial air-mass
  • E airmass
  • E air-mass

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Masse d'air qui a été sur des régions proches de l'équateur pendant plusieurs jours et qui, par suite, est devenue relativement chaude.

CONT

Les masses d'air sont classifiées selon deux caractéristiques; la température : - très chaude : masse d'air équatoriale (E), - chaude : masse d'air tropicale (T), - froide : masse d'air polaire (P), - très froide : masse d'air arctique (A), l'humidité : - sec : masse d'air continentale (c), - humide : masse d'air maritime (m).

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
DEF

Masa de aire que ha permanecido durante varios días en regiones próximas al Ecuador y que, por lo tanto, está relativamente caliente.

Record 2 2005-04-25

English

Subject field(s)
  • Satellite Telecommunications
CONT

AFSATCOM provides essential secure reliable and survivable satellite communications for Air Force Single Integrated Operational Plan (SIOP) forces and other selected high priority users.

OBS

Air Force Satellite Communications(AFSATCOM) payloads are hosted by other communications satellites, a national system for polar coverage and the DSCS III satellites for midlatitude coverage. Package D and the older Satellite Data Systems ultrahigh frequency(UHF) payloads provide 24-hour coverage of the polar regions. These payloads augment FLTSATCOM coverage at equatorial latitudes and provide polar UHF coverage to support the Single Integrated Operational Plan Aerospace supported preparations for transition of operations on polar packages from UHF to EHF.

Record 3 2004-06-23

English

Subject field(s)
  • Atmospheric Physics
  • Radio Waves
  • Remote Sensing
DEF

Multiple echoes which are at times obtained during a radio sounding of the F region of the ionosphere, especially in equatorial and high latitudes; thus the radio waves appear to be reflected from a range of altitudes.

PHR

Equatorial spread F.

Key term(s)
  • spread-F

French

Domaine(s)
  • Physique de l'atmosphère
  • Ondes radioélectriques
  • Télédétection
DEF

Échos multiples que l'on obtient par moments dans les sondages radio de la région F de l'ionosphère, spécialement aux latitudes équatoriales et aux hautes latitudes; les ondes radio paraissent ainsi être réfléchies à diverses altitudes.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
  • Ondas radioeléctricas
  • Teledetección
DEF

Multiplicidad de ecos que aparecen a veces en sondeos de la región F de la ionosfera, particularmente en latitudes altas y ecuatoriales; la reflexión de las ondas de radio parece, pues, provenir de una gama de alturas.

Record 4 2002-02-06

English

Subject field(s)
  • Air Pollution
  • Climatology
DEF

Regions next to the Equator.

French

Domaine(s)
  • Pollution de l'air
  • Climatologie
DEF

Latitudes des régions qui sont proches de l'équateur.

OBS

L'endroit où l'on passe des basses latitudes aux latitudes moyennes, la zone adjacente, est indéterminé.

OBS

Les latitudes varient entre zéro, à l'équateur, et quatre-vingt-dix à chacun des pôles.

Spanish

Campo(s) temático(s)
  • Contaminación del aire
  • Climatología
