What factors affect rainfall in middle latitudes?
The position of the ITCZ varies with the seasons. It reaches its most northern point around 10˚-20˚ N in the Northern hemisphere summer. It moves down to 10˚-20˚ S during the southern hemisphere summer. Therefore, in each hemisphere the summer is rainy for about 10˚-20˚ from the equator.
Why is Guyana more frequently affected by the ITCZ than Saint Lucia?
Guyana is more affected because it is within the ITCZ zone, 10- 12 degrees North of the Equator, St Lucia is just outside that area at 13 degrees North, So Guyana will feel the full brunt of the ITCZ than St Lucia answered by a QRC.....Trini
How do the Andes mountains negatively impact trade in south America?
Simple answer: Any mountain range that big impedes overlan travel. In the case of the Andes (as with the Rockies, basically the result of the same tectonic forces) it is East-West (& West-East) transport that is impeded. That transport problem was one of the reasons the Panama Canal was built.
At what two times of the year is the Intertropical Convergence Belt over the Equator?
The equinoxes (vernal, or spring, and autumnal, or fall) are when the Sun appears to travel directly overhead at the equator. Shortly thereafter, the intertropical convergence belt (ITCZ) will align most directly along the equator.
What parts of the earth do not experience climate changes with different seasons?
Generally countries along the equator do not experience "seasons" such as equador, congo, and indonesia to name a few. However, many countries along the equator experience wet and dry seasons as the ITCZ (intertropical convergance zone) rolls over them. This is basically the Suns path as Earth moves around it. With it comes high insolation and generally brings rain after and before it as it basically pushes water with it. This creates the wet and dry process.-J.P. lord geographer
The Intertropical Convergence Zone is .?
The intertropical convergence zone (ITCZ) is a region near the equator where winds from the northern and southern hemispheres come together. Consequences of the ITCZ's movement are the "monsoon seasons" that affect areas in the tropics, as well as the formation of tropical storms during the local hemispheric summer (north or south of the equator). Navigators in the age of sail learned to utilize the "trade winds" that blow to the east along the edge of the ITCZ.

How would the general circulation of air appear in summer and winter if the earth were tilted on its axis at an angle of 45 degrees instead of 23.5 degrees?
The ITCZ would shift further north in the northern summer and further south in the northern winter. Similarly the subtropical highs and polar fronts would shift further from the equator during the summer and closer to the equator in the winter in both hemispheres than is now the case.
Why does the location of the ITCZ vary from season to season?
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.

Where can the ITCZ be found?
The Intertropical Convergence Zone (ITCZ) is a belt of low pressure that circles the Earth near the equator, where trade winds from the Northern and Southern Hemispheres come together. It moves seasonally, following the sun's zenith, so it can be found predominantly over the oceans but can also be present over land near the equator.
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.
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.
