The Hadley Cell involves
air rising near the equator
, flowing toward the North and South Poles, returning to the surface of the Earth in the subtropics, and flowing back toward the equator at the surface of the Earth. This produces winds called the trade winds and the tropical easterlies.
How does the human production of greenhouse gases contribute to global warming quizlet?
By which mechanism do greenhouse gases contribute to global warming?
They absorb higher amounts of long wave radiation emitted from the earth’s surface as their concentration
. Methanogens produce methane gas.
Which factors or processes drive the movement of air in Hadley cells?
Which factors or processes drive the movement of air in Hadley cells? –
Cool, dry air falls towards the surface of the Earth
, where increased air pressure causes adiabatic heating, resulting in warm, dry air.
Where are Hadley cells found quizlet?
The large atmospheric circulation cells that occur
between the equator and 30° latitude in each hemisphere
are called Hadley cells. The trade winds can be found between 30° and 60°N and S latitudes.
Which of the following is a likely direction that the intertropical convergence zone ITCZ moves?
It moves
north in the Northern Hemisphere summer and south in the Northern Hemisphere winter
. Therefore, the ITCZ is responsible for the wet and dry seasons in the tropics. The sun crosses the equator twice a year in March and September, and consequently makes for two wet seasons each year.
Why does the 3 cell model exist?
three-cell model An
attempt to represent the atmospheric circulation systems over a hemisphere by three adjoining vertical cells of meridional surface motion
, transferring energy from equatorial to polar regions.
What creates Hadley cells?
Hadley cell circulation occurs at a global scale from
tropical atmospheric circulation
in which air rising near the equator flows toward the poles at 10–15 km above the surface. This circulation produces the trade winds, tropical rainbelts, hurricanes, tropical cyclones, jet streams, and subtropical deserts.
Which activities are the largest contributors of greenhouse gases?
Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from
burning fossil fuels for electricity, heat, and transportation
.
What are 5 consequences of a warming planet?
- More frequent and severe weather. Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. …
- Higher death rates. …
- Dirtier air. …
- Higher wildlife extinction rates. …
- More acidic oceans. …
- Higher sea levels.
What are the four steps involved in the greenhouse effect?
- Sunlight radiates from the sun, through space, to Earth’s atmosphere.
- The. …
- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases.
- The gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more.
Why was it important for the Soviet Union to grow cotton quizlet?
Rivers were diverted to provide water for cotton. Why was it important for the Soviet Union to grow cotton?
Cotton is an ingredient in gunpowder.
Where are Hadley cells located?
Hadley cells exist
on either side of the equator
. Each cell encircles the globe latitudinally and acts to transport energy from the equator to about the 30th latitude. The circulation exhibits the following phenomena: Warm, moist air converging near the equator causes heavy precipitation.
Which area is called doldrums?
The “doldrums” is a popular nautical term that refers to
the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters
. This NASA satellite image shows the Inter-Tropical Convergence Zone, known to sailors around the world as the doldrums.
What causes the ITCZ to move?
The shifting of ITCZ is the result of
the Earth’s rotation, axis inclination and the translation of Earth around the Sun
. Seasons are the result of this. ITCZ moves toward the hemisphere with most heat, wich are either hemisphere summers.
Is the ITCZ high or low pressure?
The Intertropical Convergence Zone is a band of
low pressure
around the Earth which generally lies near to the equator. The Intertropical Convergence Zone, or ITCZ, is a band of low pressure around the Earth which generally lies near to the equator.
How does the ITCZ affect climate?
What effect does the ITCZ have on climate? As the
ITCZ moves north with the thermal equator, it carries the mT winds over the land
. This will bring dry weather. As the ITCZ moves north with the thermal equator, it carries the mT winds over the land.
