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.
What is the ITCZ and why is it important?
The ITCZ (Intertropical Convergence Zone)
play important role in the global circulation system
and also known as the Equatorial Convergence Zone or Intertropical Front. It is a basically low pressure belt encircling Earth near the Equator. It is a zone of convergence where the trade winds meet.
What is intertropical convergence zone characteristics?
Synopsis. The Intertropical Convergence Zone (ITCZ) lies in the equatorial trough, a
permanent low-pressure feature where surface trade winds, laden with heat and moisture
, converge to form a zone of increased convection, cloudiness, and precipitation.
What is the ITCZ for kids?
The ITCZ, or
InterTropical Convergence Zone
, is a belt of low pressure girdling the globe at the equator. It is formed, as its name indicates, by the convergence of warm, moist air from the latitudes above and below the equator. This region is also known as Intertropical Front or the Equatorial Convergence Zone.
What is ITCZ write three points for the same?
Answer: The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums or the calms because of its monotonous, windless weather, is
the area where the northeast and southeast trade winds converge
. It encircles Earth near the thermal equator, though its specific position varies seasonally.
What are the effects of intertropical convergence zone?
Effects on weather
Longer term changes in the intertropical convergence zone can result
in severe droughts or flooding in nearby areas
. In some cases, the ITCZ may become narrow, especially when it moves away from the equator; the ITCZ can then be interpreted as a front along the leading edge of the equatorial air.
How intertropical convergence zone is formed?
It exists because of
the convergence of the trade winds
. In the northern hemisphere the northeast trade winds converge with southeast winds from the Southern Hemisphere. The point at which the trade winds converge forces the air up into the atmosphere, forming the ITCZ.
What happens during 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.
What causes 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.
What is another name for the ITCZ?
Known to sailors around the world as
the doldrums
, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. … And that’s why they call it the doldrums.
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.
Where is ITCZ now?
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. The location of the ITCZ can vary as much as 40° to 45° of latitude north or south of the equator on land.
What countries are affected by ITCZ?
The ITCZ is a very large feature which circles the globe. It affects many tropical areas around the world including
territories in the southern Caribbean
. The ITCZ is not stationary. It moves north of the equator during the northern hemisphere summer, bringing heavy rain to Trinidad and Tobago and Grenada.
Why does it rain at the intertropical convergence zone?
The area near the equator with low pressure and converging, rising winds is called the Intertropical Convergence Zone (ITCZ).
Water vapor condenses as air rises and cools in the ITCZ
, forming clouds and falling as rain.
What is ITCZ what is its significance Class 9?
Inter Tropical Convergence Zone (ITCZ) It is a broad trough of low pressure in equatorial latitudes from about 5° N to 5°S. … (i) The ITCZ is
a zone of convergence of North-East and the South-East trade wind
. (ii) The Northward or Southward movement of it determines the spatial distribution of rainfall.
Is ITCZ occurs in the Philippines all year round?
The Philippines only have two seasons
, which are the dry and wet seasons due to the movement of the ITCZ. The ITCZ shifts north and south seasonally with the sun, it moves north in the Northern Hemisphere summer and south in the Northern Hemisphere winter.
