Why does ITCZ make the climate hot and humid?

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.

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.

Is ITCZ hot?

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 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.

Why is the ITCZ important as a climatic control?

Intertropical Convergence Zone

The air rises so that it cools and condenses to create clouds and rain. Climate along the ITCZ is therefore warm and wet. … As the ITCZ shifts, the major wind belts also shift slightly north in summer and south in winter, which causes the wet and dry seasons in this area.

What kind of weather does the ITCZ bring?

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. In December and July, when the sun is at its greatest extent north (or south) of the equator makes for two dry seasons.

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 does ITCZ influence the climate experienced in the Philippines?

At 3:00 a.m., the Low Pressure Area (LPA) was estimated at 265 kilometers southwest of Puerto Princesa City, Palawan. As the Tail-end of a Cold Front dampens the eastern sections of Southern Luzon and Visayas, the Northeast Monsoon brings rains in portions of Northern Luzon.

Why is ITCZ called doldrums?

The rising air mass finally subsides in what is known as the horse latitudes, where the air moves downward toward Earth’s surface. Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. … And that’s why they call it the doldrums.

What causes rainy and dry seasons?

In many tropical and subtropical regions, rainfall varies much more than temperature does. Also, because the earth tilts, the direct sun rays, and in turn, the tropical rain belt, shifts from the northern to the southern tropics. So these areas experience just two seasons: a wet season and a dry season.

How does the ITCZ affect monsoons?

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. … This is where monsoon rainfall occurs.

Where does the ITCZ shift during the summer season?

It moves north in the Northern Hemisphere summer and south in the Northern Hemisphere winter.

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.

Why does the ITCZ shift with the seasons?

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 wet season occur in the Philippines?

Rainfall. Monsoons are large-scale sea breezes which occur when the temperature on land is significantly warmer or cooler than the temperature of the ocean. … The summer monsoon brings heavy rains to most of the archipelago from May to October.

How does the ITCZ account 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.
