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 significance of the intertropical convergence zone?
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.
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.
What is ITCZ how it affects the Indian climate?
These winds collect moisture as they travel over the warm Indian Ocean . In the month of July, the ITCZ shifts to 20°-25° N latitude and is located in the Indo-Gangetic Plain and the south-west monsoons blow from the Arabian Sea and the Bay of Bengal. The ITCZ in this position is often called the Monsoon Trough.
What are the effects of the intertropical convergence zone in Africa?
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.
What are the characteristics of Intertropical Convergence Zone?
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.
What is the ITCZ how does it influence the climate of Africa?
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 . ... Areas near the equator in western and southern Africa have a single intense rainy season from July to September.
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.
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 location of the intertropical convergence zone 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.
What kind of weather is generally associated with the Intertropical Convergence Zone?
The ITCZ is generally near the equator; weather is characterized by clouds, thunderstorms and rain .
Where is the ITCZ located now?

Why the ITCZ is mostly north of the equator?
ITCZ stands for Intertropical Convergence Zone. It is a region of clouds, rain, low level convergence and rising air. ... 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 .
How is India’s climate?
Most of Northeast India and much of North India are subject to a humid subtropical climate and a subtropical highland climate. Though they experience warm to hot summers, temperatures during the coldest months generally fall as low as 0 °C (32 °F). ... Humid subtropical regions are subject to pronounced dry winters.
What are the factors affecting Indian monsoon?
- Intense low-pressure formation over the Tibetan Plateau.
- The permanent high-pressure cell in the South of the Indian Ocean.
- Subtropical jet stream.
- African Easterly jet (Tropical easterly jet)
- Inter-Tropical Convergence Zone (ITCZ)
What does ITCZ stand for?
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.
