The ITCZ varies according to the seasons due to the same factors that cause the seasons themselves... the earth tilts during the year and that is what causes the seasons. The ITCZ over land tends to follow the sun's zenith point... that is, the ITCZ on land tends to form south of the equator when it is summer on the southern hemisphere (December) and north of the equator when it is summer on the northern hemisphere (June).
Also, you may want to take a look at this month's (March 2011) issue of Scientific American, where some hypothetize that the ITCZ could shift a little bit to the north of the Equator, causing disrupting paterns of floods and drought; or this week's issue of Nature (Nature 470, page 344) which contains articles about how human activity may be causing intense flooding.

How is monsoon circulation affected by the position of the ITCZ?
ITCZ represent the band of low pressure belt around the globe, usually centered at equator, but follow the vertical sun with season. Since the winds are moved towards zones of lowest pressures, the ITCZ is the location where equatorial winds on either hemispheres merge, resulting in rising of air there and formation of cloud bands. During summer, sun is migrates to the north of equator and hence the ITCZ follows the sun. As a result the southeast trade winds (easterly winds) cross the equator towards the low pressure ITCZ. On crossing equator, the wind turn to the right in the northern hemisphere due to Coriolis force and blow as southeasterly winds. These winds blowing over ocean brings abundant moisture along with it. Hence when the ITCZ is over continental landmass of India, the moisture laden winds blow across the continent, where the geographical reliefs like Western Ghats and Himalayas cause the air to rise. Accompanied by the rising of moisture laden air, adiabatic cooling and condensation occurs at heights which triggers rainfall over Indian landmass.
The Intertropical Convergence Zone ITCZ is characterized by what type of pressure?
low pressure.
The intertropical convergence zone ITCZ is associated with what?
subtropical high-pressure development.
Which type of cloud would dominate the weather in a region under the ITCZ?
cumulonimbus!
Where do northeast and southeast trade winds meet?
The equator, better known as the Intertropical Convergence Zone; ITCZ.
How does the ITCZ affects the Caribbean?
petite careme or dry season
How is salinity affected by ITCZ?
Intertropical Convergence Zone (ITCZ) is where the convergence of air from north and south around the equator. ITCZ occur along the equatorial, continuously. Heat from the Sun causes the air to expanded and rises up to the atmosphere, in mass, result in precipitation. With the constant heat supply from the Sun and precipitation, ITCZ is a zone where is constantly hot and humid. The precipitation has caused the sea water salinity to be lower explained the lower SSS around equator but SST remain to be high. However, the ITCZ will shift its location from time to time according to season as it only occur in the area with intense sunlight. Thus, in tropical area, there will have a season with high precipitation and causes the SSS to Intertropical Convergence Zone (ITCZ) is where the convergence of air from north and south around the equator.

What effect does the location of the Philippines have on its average air temperature?
the location of the phlippines is the tropical convergence zone or itcz
The dry season in the tropical monsoon climate occurs when?
The ITCZ is not over head.
what is the location of the ITCZ?
The equator. The ITCZ is usually found within 350 km of the equator; about 80–300 km wide and 5° north and south from the equator. The position of the ITCZ varies seasonally (Figure I2), being drawn toward the areas of the most intense solar heating.
Why does itcz wind occur?
why ITCZ occur
What is found in ITCZ?
Different kinds of Monsoons are found in the ITCZ
What countries in the Caribbean are affected by the itcz?
which countries in the carribbea are not affected by itcz
When are green apples in season?
Traditionally mid to late September but this can often vary due to weather, location, etc.
What is itcz mean?
Well in Earth Science terms. ITCZ stands for: Intertropical Convergence Zone
What winds converge at ITCZ?
Northeast and southeast trade winds converge at the ITCZ. (Inter-tropical Convergence Zone)
What is the meaning of ITCZ?
ITCZ stands for Inter-Tropical Convergence Zone and refers to the band of weather that circles the Earth at or near the equator. Weather within the ITCZ can be quite violent as the weather systems from the northern and southern hemispheres converge. Thunderstorms within the ITCZ can reach heights of 80,000 plus feet.
