The ITCZ is commonly defined as an equatorial zone where the trade winds converge. Rainfall seasonality is traditionally attributed to the north–south migration of the ITCZ, which follows the sun. Although this is largely valid over the equatorial oceans, the ITCZ and the region of maximum rainfall can be decoupled over the continents.
A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. [1] This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation . [ 1 ]
This seasonal rainfall is impacted by the oscillation and migration of the Intertropical Convergence Zone (ITCZ) across the equator of northern region of the country in July and August, to its south bending its position over the southern Kenya in January and February. Climate change is of great concern in Ethiopia, especially since the 1970s.
A monsoon (/ m ɒ n ˈ s uː n /) is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation [1] but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator.
The monsoon trough is a convergence zone between the wind patterns of the southern and northern hemispheres. It is a portion of the Intertropical Convergence Zone in the Western Pacific, [1] [2] and is depicted by a line on a weather map showing the locations of minimum sea level pressure. [1]
Global climate is greatly influenced by the structure and behavior of the Hadley circulation. The prevailing trade winds are a manifestation of the lower branches of the Hadley circulation, converging air and moisture in the tropics to form the Intertropical Convergence Zone (ITCZ) where the Earth's
This altitudinal zone is characterized for presenting an average temperature ranging between 10 and 17 °C (50.0 and 62.6 °F) while rainfall reaches a yearly average of 2,000 mm (78.7 in). The Colombian capital city Bogotá is located in this altitudinal zone.
The current climate on Mount Kenya is wet, but drier than it has been in the past. The temperatures span a wide range, which diminishes with altitude. In the lower alpine zone they usually don't go below 12 °C (54 °F). [3] Snow and rain are common from March to December, but especially in the two wet seasons. The wet seasons combined account ...
