What causes the ITCZ to migrate?
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.
Why does the ITCZ shift above and below the equator during the summer in each hemisphere?
This means that, in summer, air over land is heated more than air over ocean, which shifts the ITCZ toward land regions. In regions where continents lie north or south of the equator, as in Asia and Australia, this causes the ITCZ to shift farther off the equator during the summer season.
How does the location of the ITCZ change over time?
How does the location of the Intertropical Convergence Zone (ITCZ) change over time? The ITCZ migrates south of the equator in Northern Hemisphere winter and north of the equator in Northern Hemisphere summer. Equatorial regions receive more direct sunlight than other areas.
How does the ITCZ shift quizlet?
the itcz is a zone of convergence at the thermal equator where the trade winds meet. It is a low pressure zone, that migrates with the changing position of the thermal equator. the movement of the thermal equator shifts the belt of planetary winds and pressure belts to the North and South annually.
In which direction does the ITCZ shift in winter?
The ITCZ follows the sun in that the position varies seasonally. 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.
Why is ITCZ called doldrums?
The rising air mass finally subsides in what is known as the horse latitudes, where the air moves downward toward Earth’s surface. Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. And that’s why they call it the doldrums.
What happens at the ITCZ?
The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.
Where can the subtropical jet stream be located quizlet?
Where is the subtropical jet located? The subtropical jet located around 30°N. Jet streams vary in height of four to eight miles and can reach speeds of more than 275 mph (239 kts / 442 km/h).
How does the ITCZ move from summer to winter?
The ITCZ follows the sun in that the position varies seasonally. It moves north in the Northern Hemisphere summer and south in the Northern Hemisphere winter. Further away from the equator, the two wet seasons merge into one, and the climate becomes more monsoonal, with one wet season and one dry season.
Why does the ITCZ shift northward between December and June?
Most rain on Earth falls in the tropical rain belt known as the Intertropical Convergence Zone (ITCZ), which on average lies 6° north of the equator. So when the northern hemisphere warms, for example, because northern ice cover and with it the polar albedo are reduced, the ITCZ shifts northward.
