Frequent question: How the ITCZ accounts for the climate of West Africa?

In recent decades the ITCZ over West Africa has been observed to shift northward (Fontaine et al., 2011), increasing rainfall over the Sahel. Over Western Africa the ITCZ is an impor- tant driver of regional climate, controlling the distribu- tion of winds and precipitation, which can impact soil and vegetation.

How does ITCZ affect 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.

How does ITCZ influence climate?

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.

What is the ITCZ in Africa?

The intertropical convergence zone (ITCZ) has. long been assumed to be a major control on tropical rainfall over both oceans and land. Over Africa, the cycle of the rainfall seasons is generally associated with its north–south displacement as this zone “follows” the sun.

What is the climate for West Africa?

Climate. West Africa has wet and dry seasons resulting from the interaction of two migrating air masses. … The lowland climates of West Africa are characterized by uniformly high sunshine and high temperatures throughout the year; mean annual temperatures are usually above 18°C.

How does water regulate climate?

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …

What weather does the ITCZ bring?

The Intertropical Convergence Zone, or ITCZ, is a band of low pressure around the Earth which generally lies near to the equator. The trade winds of the northern and southern hemispheres come together here, which leads to the development of frequent thunderstorms and heavy rain.

How does ITCZ take place does ITCZ happen in all parts of the world?

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.

IT IS IMPORTANT:  You asked: What are the limits of using an ecological approach to explain and solve urban health problems?

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

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

How does ITCZ affect the formation of typhoon?

Tropical cyclone formation also requires a trigger that initiates convection. One such trigger is the intertropical convergence zone (ITCZ), where warm sea-surface temperatures and convergence of surface trade winds foster convection (rising air). Conveniently, the ITCZ forms near the warmest surface waters.

How ITCZ influence the climate of Uganda?

The climate in Uganda is controlled by the oscillating effects of the Inter-Tropical Convergence Zone (ITCZ), which sees the convergence of the rain bringing Atlantic westerlies and Indian Ocean easterlies and the dry north-east and south-east monsoon winds.

Which climate zone is characterized by warm summers and cool wet winters?

Mediterranean climate, major climate type of the Köppen classification characterized by hot, dry summers and cool, wet winters and located between about 30° and 45° latitude north and south of the Equator and on the western sides of the continents.

What is the main climate found in northern Africa?

Current Climatology of North Africa

Along the coast, North Africa has a Mediterranean climate, which is characterized by mild, wet winters and warm, dry summers, with ample rainfall of approximately 400 to 600 mm per year.

How is the climate of Africa?

Africa’s climate is dominated by desert conditions along vast stretches of its northern and southern fringes. The central portion of the continent is wetter, with tropical rainforests, grasslands, and semi-arid climates.

What are the three climate zones of West Africa?

West African domain divided into three climatic zones: Guinea (4°N–8°N), Savanna (8°N–11°N), and Sahel (11°N–16°N) (source: [49, 50]).

Which climate type covers the majority of West and Central Africa?

Tropical monsoon climates are most found in southern Asia and West Africa.
