There's a trend of convergence.
The marked seasonal pattern of precipitation is caused by the north and south movement of the intertropical convergence zone (ITCZ), which shifts with the Sun.
The rain-harmattan transition phase marks the onset of the dry season due to the movement of the intertropical convergence zone interplay between (north-easterly and south-westerly) trade winds and monsoonal circulation.
This is the Australian monsoon, the intensity of which has varied with the movement of the Intertropical Convergence Zone (ITCZ) over the past 30,000 years (cf., Ding et al. 2013; Kuhnt et al. 2015; Mohtadi et al. 2011).
Activity during the season was hindered by the northward movement of the Intertropical Convergence Zone (ITCZ).
In contrast, in the Indian Ocean and Western Pacific in both hemispheres, tropical cyclogenesis is influenced less by tropical easterly waves and more by the seasonal movement of the Intertropical Convergence Zone and the monsoon trough.
Micha Gaillard, a member of the leftist National Congress of Democratic Movements, also a part of Convergence, said the army was not crucial to achieving Haiti's security goals.
Worldwide, there seems to be some movement towards convergence of breast cancer mortality rates.
Located only ca. 244 km northeast from the Atlantic Ocean (Fig. 1), it is subjected to the northward and southward movement of the inter-tropical convergence zone (ITCZ) and consequent effect of primary air masses (mainly the southwest monsoon).
The general climate is characterised by the seasonal changes in water availability and fires which are influenced by the dry and rainy seasons, also linked to the movement of the Inter-Tropical Convergence Zone (ITCZ, [36]).
