Intertropical Convergence Zone of human errors which ultimately doomed the flight. Most aircraft flying these routes are able to avoid the larger convective cells without incident. Intertropical Convergence Zone The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums or the calms, is the area encircling Earth near the Equator, where the northeast and southeast trade winds converge. The ITCZ was originally identified from the 1920s to the 1940s as the "Intertropical Front" ("ITF"), but after the recognition in the 1940s and the 1950s of the significance of wind field convergence in tropical weather production, the term "ITCZ" was then applied.

Convergence-divergence zone Convergence-divergence zone The theory of convergence-divergence zones was proposed by Antonio Damasio, in 1989, to explain the neural mechanisms of recollection. It also helps to explain other forms of consciousness: creative imagination, thought, the formation of beliefs and motivations ... It is based on two key assumptions: imagination is a simulation of perception, brain registrations of memories are self-excitatory neural networks (neurons can activate each other). A convergence-divergence zone (CDZ) is a neural network which receives convergent projections from the sites whose activity is to be recorded, and which returns divergent projections to the same sites. When an experiment is
