Tropical Convergence Zones Flashcards
A zone of divergence is
Where winds go in different directions
Converging winds include
The trade winds, which meet at the equator in a zone termed the Inter-Tropical Convergence Zone
What are horse latitudes?
Two zones of divergence which occur in the subtropical high pressure zones where the winds are usually fairly light
What is climate like in the horse latitudes?
Clear skies, abundant sunshine, low rainfall and calm winds
When air masses from different source regions meet
Air at the edge begins to use colder air to force the warmer air upwards
Condensation takes place in upper parts - a The front
Where the trade wind belt of the northern latitudes meets the trade wind belt if the southern latitudes within the equatorial belt
An inter-tropical front is formed
The weather associated with an inter tropical front depends on
Whether the front has formed over the oceans or the continents
Air masses converging towards the inter-tropical front over oceans are
Most in the lower layers and fairly dry at higher levels
At convergence there is some instability and large cumulus clouds appear leading to intense shower and thunder conditions
Within Equatorial areas the vertical movement of air through convection produces convectional rain. This belt of Equatorial rainfall moves
North or South
With the Suns declination of about 5 degrees latitude either side of the equator
A zone of convergence is
Where winds meet
