Tri cellular model Flashcards
The Hadley cell can be as tall as…
17 km reaching troposphere.
At Hadley cell what type of clouds are formed?
Cumulonimbus clouds.
Doldrum is formed by…
the converging air, which heats up by the latent heat and insolation.
For the formation of the hurricane the water must…
have more than 27.5 degrees and must be at least 60m deep.
Three major cells:
Hadley, Ferrel and Polar
The cells shift northwards and southwards with…
the ITCZ.
At 30 degrees north-south…
Hadley and Ferell cell meet. It is tropic of cancer. There is STJS and high pressure.
At 60 degrees north-south…
Ferrel and Polar cell meet. (Europe). There is PFJS and area of low pressure.
STJS stands for…
subtropical jet stream(down). The trade winds.
PFJS stands for…
polar front jet stream(up)
The cells get smaller as they move…
towards the poles as there is less isolation in the system.
At summer and winter solstice…
21 June and December, the ITCZ is the furthest from the equator.
ITCZ stands for…
inter-tropical convergence zone
Polar cell reaches hight…
7-10km.
