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 type of weather would you expect to find 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.
What type of weather would you expect to find at the equator?
Tropical climates are found near the equator. They are warm and humid and experience a lot of rainfall, particularly during their wet season, which can occur once or twice each year. Rain forests grow in tropical climates. Deserts are places where there is very little rainfall throughout the year.
Which type of rainfall is associated with the ITCZ?
The air cools and rises (see image below), causing water vapor to be “squeezed” out as rain, resulting in a band of heavy precipitation around the globe. Air that rises along the ITCZ moves away from the equator and sinks in the subtropics at the Horse Latitudes, rounding out the Hadley Circulation.
How is ITCZ responsible in bringing rainfall to our country during summer?
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.
Where does the ITCZ shift during the summer season?
It moves north in the Northern Hemisphere summer and south in the Northern Hemisphere winter.
How does the location of the Philippines influence its climate and weather?
The Philippines is located in the western Pacific Ocean, surrounded by naturally warm waters that will likely get even warmer as average sea-surface temperatures continue to rise. To some extent, this is a normal pattern: the ocean surface warms as it absorbs sunlight.
How does ITCZ affect the weather in the Philippines?
ITCZ is characterized as an area where winds coming from the Northern and Southern Hemispheres meet; this interaction results to rains in the affected areas. … In the rest of the country including Metro Manila, partly cloudy to cloudy skies will prevail only with isolated rain showers or thunderstorms.
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.
How does the ITCZ account for the climate of West Africa?
West Africa’s climate is controlled by the interaction of two air masses, the influence of which varies throughout the year with the north-south movement of the Intertropical Convergence Zone (ITCZ). … Temperatures in the lowlands of West Africa are high throughout the year, with annual means usually above 18°C.
Which major biomes and climate types are associated with Convectional rain and the ITCZ?
The sets of major biomes and climate types associated with convectional rain and the ITCZ are tropical forest; humid and seasonally humid tropical climates.
Why is it warmest at the equator because it?
Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. … This means more heat from the sun makes it to the surface of the Earth.
How ITCZ affect the rainfall in India?
Variation in location of the ITCZ affects rainfall in the equatorial regions, as it is the region of low atmospheric pressure pulling the moisture laden winds and causing them to rise. … This encourages the development of thermal low over the North and Northwest India.
Why does the location of the ITCZ change?
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 does the ITCZ shift northward between December and June?
Most rain on Earth falls in the tropical rain belt known as the Intertropical Convergence Zone (ITCZ), which on average lies 6° north of the equator. … So when the northern hemisphere warms, for example, because northern ice cover and with it the polar albedo are reduced, the ITCZ shifts northward.
Where is precipitation the greatest?
Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.
What is climate Ncert?
Climate refers to the sum total of weather conditions and variations over a large area for a long period of time (more than thirty years). Weather refers to the state of the atmosphere over an area at any point of time.
What type of climate prevails in India?
The type of climate that prevails over India is Tropical monsoon type of climate. It is because India lies in the tropical belt and the climate is influenced by the monsoon winds which are confined to the Tropics.
Which of the following influences the climate of the Philippines?
Typhoons have a great influence on the climate and weather conditions of the Philippines. A great portion of the rainfall, humidity and cloudiness are due to the influence of typhoons.
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.
Which of the following best describe the movement of the ITCZ from January to July?
Which of the following best describes the movement of the ITCZ from January to July? It moves northward (ITCZ follows the sun). Which of the following pairs of terms are best associated with subtropical high-pressure cells? … Where do the winds that converge at the ITCZ originate?
Why do climates vary in the different regions in the Philippines?
Essentially, there arc two main reasons that climate varies from place to place; first, the amount of energy arriving from the sun, and second the circulation of the atmosphere and oceans which carry heat and moisture from one placc to another.
