These fluctuations in ITCZ positioning had robust effects on climate; for instance, displacement of the ITCZ may have led to drought in the Sahel in the 1980s. trade winds. The rising air then proceeds south and north toward the poles. Winds are caused by differences in air pressure. [17][18], Atmospheric convection may become stronger and more concentrated at the center of the ITCZ in response to a globally warming climate, resulting in sharpened contrasts in precipitation between the ITCZ core (where precipitation would be amplified) and its edges (where precipitation would be suppressed). The doldrums encircle the Earth near the equator, ranging from about five degrees north to about five degrees south of it. The rising air mass finally subsides in what is known as the horse latitudes, where the air moves downward toward Earths surface. The doldrums are notably described in Samuel Taylor Coleridge's poem The Rime of the Ancient Mariner (1798) and also provide a metaphor for the initial state of boredom and indifference of Milo, the child hero of Norton Juster's classic children's novel The Phantom Tollbooth.
