Earth sciences portal Weather portal. At this time scale, there is still a lot of variation between the East and Central Pacific. Twin Convergence Zones. Rain areas in the equatorial Pacific are widely scattered and very localized with areas of heavy rain separated by vast areas of no rain. As distance from the equator increases, the duration, amount and reliability of precipitation all decrease. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant. Jump to navigation. On a large scale, there are few air masses which shape the rainfall characteristics of tropical Africa. As the heat capacity of the oceans is greater than air over land, migration is more prominent over land. The ITCZ has been called the doldrums by sailors because there is essentially no horizontal air movement, that is, no wind the air simply rises.

The cause and impact of the. Precipitation and the Inter Tropical Convergence Zone (ITCZ). The most important component of climate is precipitation, because rainfall provides water for.
NWS JetStream InterTropical Convergence Zone
The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums or the calms Variation in the location of the intertropical convergence zone drastically affects rainfall in many equatorial nations, resulting in the wet and dry.
But, if rainfall is average over a week 3rd figurea distinctive banding feature begins to emerge near the Equator, which is the hallmark of the ITCZ.
The extreme, of course, is the Sahara desert in northern Africa. This warms the air and the ocean, causing warm buoyant air to rise and a band of lower pressure to form. This idea should sound familiar to you, because the White Nile starts in the equatorial region, and it does not have a major flood season. For instance, when the ITCZ is situated north of the Equator, the southeast trade wind changes to a southwest wind as it crosses the Equator.
Here, we. The ITCZ is a zone of convergence at the thermal equator.
It is a low pressure belt, migrating with the thermal equator, resulting in a band of heavy precipitation. The Intertropical Convergence Zone (ITCZ) lies in the equatorial trough, Precipitation in the Atlantic ITCZ is enhanced when the MJO convection center is over.
This reliable circulation feeds the lush rain forests of central Africa, and also defines the limits of the Sahara desert.

In northern Nigeria, Kano averages Then by merging the estimates from multiple satellites, surface precipitation maps can be produced half-hourly at 0.
Tropical cyclogenesis depends upon low-level vorticity as one of its six requirements, and the ITCZ fills this role as it is a zone of wind change and speed, otherwise known as horizontal wind shear. Look up doldrums in Wiktionary, the free dictionary.

Calm periods within the doldrums could strand ships for days or weeks.
