Why does the Inter tropical Convergence Zone shift?

Asked by: Vanessa Martel

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 are the tropics shifting?

Earth’s tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research. Earth’s tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research.

Why does the ITCZ shift more in latitude over the continents during the monsoons than over the ocean?

Since water has a higher heat capacity than land (the ocean heats up more slowly than the land), the ITCZ propagates poleward more prominently over land than over water, and over the Northern Hemisphere than over the Southern Hemisphere.

Why does the ITCZ shift towards the hemisphere that is experiencing summer?

(2006) have revealed one important driver of ITCZ shifts: differential heating or cooling of the hemispheres shifts the ITCZ toward the differentially warming hemisphere. So when the northern hemisphere warms, for example, because northern ice cover and with it the polar albedo are reduced, the ITCZ shifts northward.

What causes the ITCZ to move so far north in Asia?

Winds change through the year.



During June and July, the Northern Hemisphere is heated more strongly by the Sun, so the ITCZ and its rising hot air lie a little north of the equator and winds blow from the Southern Hemisphere across the equator to reach the ITCZ in the Northern Hemisphere.

Why do you think that the ITCZ shifts to the north in July and shifts to the south in January?

The position of the ITCZ varies predictably throughout the year. Although it remains near the equator, the ITCZ moves farther north or south over land than over the oceans because it is drawn toward areas of the warmest surface temperatures.

Where does the ITCZ shift during the summer season?

( The shift of the position of Inter Tropical Convergence Zone (ITCZ) in summer, over the Ganga plain (this is the equatorial trough normally positioned about 5°N of the equator. It is also known as the monsoon- trough during the monsoon season).

Why does the ITCZ move further north of the equator during our summer than it moves south of the equator during the Southern Hemispheres summer?

The ITCZ has a mean position north of the equator because there is much more landmass in the Northern Hemisphere as compared to the Southern Hemisphere. Look at a globe and notice how much more land there is in the tropics in the Northern Hemisphere.

How does ITCZ affect the changes of the weather in the Philippines?

Seasonal shifts in the location of the ITCZ drastically affects rainfall in many equatorial nations, resulting in the wet and dry seasons of the tropics rather than the cold and warm seasons of higher latitudes. Longer term changes in the ITCZ can result in severe droughts or flooding in nearby areas.

What is the tropical convergence zone explain?

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.

Why is the ITCZ always almost in the north?

The ITCZ stays north of the equator because SST is higher; and the SST is higher north because the ITCZ stays there.

What is the inter tropical convergence zone ITCZ )? How does it attract south monsoon What are the important factors which influence the mechanism of Indian weather?

The ITCZ or Inter-Tropical Convergence Zone is a low-pressure belt. ITCZ circles the Earth generally near the equator where the trade winds of the Southern & Northern hemispheres come together. It is featured by together activity which produces often forceful thunderstorms over large areas.

Why the ITCZ is mostly north of the equator?

The Intertropical Convergence Zone (ITCZ), monsoon and dry …

Why is the ITCZ above the equator?

The ITCZ has a mean position north of the equator because there is much more landmass in the Northern Hemisphere as compared to the Southern Hemisphere. Look at a globe and notice how much more land there is in the tropics in the Northern Hemisphere. Land heats more than water.

How does the latitude of a region affect its climate?

There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.

Why is latitude the most important factor that affects climate?

Latitude is the most important climatic control, due to the effect is has on the amount of solar radiation reaching the Earth’s surface. The seasonal changes in incoming solar radiation, as well as the length of the day, vary with latitude.

How does ITCZ affect Indian monsoon?

The significance of ITCZ for India is its contribution to the Indian monsoon. In July when ITCZ is located in the north, it creates the Monsoon Trough. This encourages the development of thermal low over the North and Northwest India.

What happens at the intertropical convergence zone?

The rising air produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions of calm surface air, occur within the zone. The ITCZ shifts north and south seasonally with the Sun. Over the Indian Ocean, it undergoes especially large seasonal shifts of 40°–45° of latitude.

What are the characteristics of ITCZ?

The ITCZ is characterized by low atmospheric pressures (low intertropical pressures), as a consequence of the upward movement induced by the trade winds convergence. It results in high atmospheric pressure in the upper troposphere.
