What is the cause and effect of ITCZ?

The ITCZ is a narrow zone where trade winds of two hemispheres collide which causes erratic weather patterns with stagnant calms and violent thunderstorms. It is characterised by convective activity which generates often vigorous thunderstorms over large areas.

What is ITCZ and what is its significance?

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 write its three significance?

(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. (iii) This zone is the wettest area on the planet, which does not have a dry season. Thus, it is constantly hot and humid.

What is ITCZ explain in three to four points?

The Intertropical Convergence Zone, or ITCZ, is a zone that surrounds the Earth around the equator, where the Northern and Southern Hemisphere trade winds meet. The International Tropical Climate Zone (ITCZ) is a belt of clouds that circles the globe around the Equator.

What are the effects of ITCZ?

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 ITCZ is formed?

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 class ninth?

It is in this area that the northeast and southeast trade winds converge. Therefore, the name Intertropical Convergence Zone (ITCZ). The ITCZ is called the near-equatorial trough when it lies near the geographic Equator and referred to as monsoon trough when it merges with a monsoonal circulation.

What effect does the ITCZ have on the weather of the Philippines?

The Intertropical Covergence Zone (ITCZ), which is an imaginary line where the Northern and Southern air meet, brings cloudy skies with scattered rain showers and thunderstorms in Metro Manila, Central Luzon, CALABARZON, MIMAROPA, Western and Central Visayas and Mindanao.

What countries are affected by the 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.

What is Intertropical Convergence Zone Upsc?

The Inter Tropical Convergence Zone (ITCZ,) is a broad trough of low pressure in equatorial latitudes. This is where the northeast and the southeast trade winds converge. This convergence zone lies more or less parallel to the equator but moves north or south with the apparent movement of the sun.

Which climate is influenced by the ITCZ most of the year?

-The ITCZ migrates with the high Sun and influences the Tropical Monsoon climates.

Which of the following statement is correct about the intertropical convergence zone ITCZ?

Statement 2 is correct: Intertropical Convergence Zone (ITCZ) is a zone where the trade winds of the Northern and Southern Hemispheres come together.

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).

Does ITCZ affect temperature?

Because the center of the ITCZ in the dry season lies over the ocean, low pressure is created there whilst pressure on land is higher. This forces cooler wind from the NORTH EAST to head south towards the ocean, leading to cooler temperatures.

Why does the ITCZ shift seasonally?

The ITCZ moves throughout the year and follows the migration of the Sun’s overhead position typically with a delay of around 1-2 months. As the ocean heats up more slowly than land, the ITCZ tends to move further north and south over land areas than that over water.

Why is ITCZ called doldrums?

Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that’s why they call it the doldrums.

How does the ITCZ affect monsoon?

As the ITCZ swings north during the summer months, it brings monsoon rains to Kozhikode, India. As the ITCZ drops south during summer in the Southern Hemisphere, it brings monsoon rains to Darwin, Australia. The location of monsoon rainfall is affected by the fact that land can’t hold onto heat as well as the ocean.

What is not true about ITCZ?

Explanation: The Inter-tropical convergence zone rather has rising air, with common thunderstorms and attendant precipitation and is known by seamen as the doldrums. Inter-tropical convergence zone is where the trade winds collide. Hence, it is not a high pressure zone with sinking air.
