Notes
albedo
the proportion of solar radiation which is reflected by the earth's surface (usually about 40%)
N




atmosphere
the air or mixture of gases which envelops the earth
N
àile

atmospheric

A
-


Use the genitive singular of the noun, e.g. "cudrom an àile" (atmospheric pressure)
atmospheric cell
a vertical circulation cell in the lower atmosphere associated with meridional flow or circulation of the air.





atmospheric circulation
the general circulation of the atmosphere, covering all the movement of the air enveloping the earth in the lower and upper atmosphere resulting from the unequal heating of the earth and its atmosphere mainly because of the imbalance of insolation between higher and lower latitudes.





climate
the average of weather conditions typical of a region
N
gnàth-shìde, gnàth-aimsir
F
gnàth-shìdean (pl), gnàth-shìde (gen)
"gnàth" means "usual" or "customary"; "sìde" and "aimsir" mean "weather".
climate change

N
atharrachadh gnàth-shìde



Doldrums
The equatorial belt of low atmospheric pressure where the NE and SE Trade Winds coverge on and meet each other, producing calms and light surface winds and a strong upward movement of air.





global warming

N
blàthachadh na cruinne



greenhouse effect
the phenomenon by which the atmosphere near the earth's surface holds heat
N




Hadley Cells
One of the major components of the atmospheric circulation, they are thermally driven cells occuring on both sides of the equator. They are caused by air being heated over the equator, rising to higher altitudes, cooling and descending near the tropics and setting up winds blowing back to the equator to balance atmospheric pressure. Named after the meteorologist who first described them. The other cells of the atmospheric circulation are the Polar Cells and the Ferrel Cells which lie between the Hadley Cells and the Polar Cells.





insolation
radiation received by the earth from the sun (INcoming SOlar radiATION)
N




Intertropical Convergence Zone (ITCZ)
A zone of low atmospheric pressure near and more or less parallel to the equator, where the NE and SE Trade Winds meet, being thus associated with the doldrums.

ozone layer

N




Planetary Wind System
The general distribution of winds throughout the lower atmosphere, which -determined by differences in insolation - would be set up similarly in any rotating planetpossessing an atmosphere





pressure
usually refers to atmospheric pressure or the "weight" of the air pressing down of the earth's surface
N
cud(th)rom
M

e.g. "cudrom an àile" (atmospheric pressure); "cudrom" means "weight".
radiation
the process by which a body eg the sun emits energy
N




weather
the condition of the atmosphere(in terms of temperature, humidity etc) at any one place, at any one time
N
sìde, aimsir
F


wind
a horizontal movement of air across the surface of the earth
