passaat(winden) | bestendige winden van het planetaire windsysteem aan beide kanten van de equator, treden op het noordelijk halfrond op als noordoostpassaat, op het zuidelijk halfrond als zuidoostpassaat. Passaatwinden ontstaan door het verschil in luchtdruk tussen subtropische hogedrukgebieden en de strook met lagedruk aan de equator en bereiken een windkracht tussen 4 en 5. Zij bereiken een hoogte van 2 km en vormen op de overgang tot de de daarbovenliggende luchtmassa's de zogenaamde passaatinversie. | |||
Passat(winde) | beständige Winde (globale Bodenwinde) des planetarischen Windsystems beiderseits des Äquators, treten auf der Nordbreite als Nordostpassat, auf der Südbreite als Südostpassat auf. Passatwinde entstehen durch das Druckgefälle zwischen subtropischen Hochdruckzonen und der Tiefdruckrinne des Äquators und erreichen Windstärken zwischen 4 und 5. Sie reichen in der Höhe bis zu 2 km und bilden am Übergang zu den darüberliegenden Luftmassen die sogenannte Passatinversion. | |||
trade winds | a pattern of winds that occur around
the equatorial region. The winds prevail in the tropics, where they blow
from the high pressure area in the horse
latitudes towards the low pressure area around the equator.
They blow predominantly from the northeast (northeast
trades) in the northern hemisphere and from the southeast in
the southern hemisphere (southeast
trades). The name derives from 'trade', meaning 'path' or 'track,' and thus the phrase 'the wind blows trade,' that is to say, on track. |

alisei | Venti costanti dominanti nell'Oceano Atlantico e la parte orientale dell'Oceano Pacifico. Spirano da Nord-Est nell'emisfero boreale e da Sud-Est nell'emisfero australe. Si generano normalmente per l'elevato innalzamento dell'aria all'Equatore (dovuto al forte riscaldamento) che richiama aria in superficie dalle zone polari, generando un moto da Nord / Sud verso l'Equatore. Per effetto della rotazione terrestere si genera uno spostamento della direzione verso Est. | |||

In
the zone between about 30°N and 30°S, the surface air flows
toward the equator and the flow aloft is poleward. A low-pressure area
of calm, light variable winds near the equator is known to mariners
as the doldrums. Around 30°N and S, the poleward flowing air begins
to descend toward the surface in subtropical high-pressure belts. The
sinking air is relatively dry because its moisture has already been
released near the Equator above the tropical rain forests. Near the
center of this high-pressure zone of descending air, called the Horse
Latitudes, the winds at the surface are weak and variable. The name
for this area is believed to have been given by colonial sailors, who,
becalmed sometimes at these latitudes while crossing the oceans with
horses as cargo, were forced to throw some overboard to conserve water. |
