It's a place for trade winds to meet other trade winds. Luis added four shells to his collection. Low atmospheric pressure and a lack of substantial wind characterize the region. He describes the area as being quite far north of the equator and having high pressure. Which blow toward the low-pressure areas of the westerlies? [8] The southern ITCZ in the southeast Pacific and southern Atlantic, known as the SITCZ, occurs during the Southern Hemisphere fall between 3 and 10 south of the equator east of the 140th meridian west longitude during cool or neutral El NioSouthern Oscillation (ENSO) patterns. Meanwhile, horse latitudes are located at 30 degrees north and south latitude. The dry descending branch is the horse latitudes. Answer: Trade wind cells. Omissions? The IPCC Sixth Assessment Report indicated "medium agreement" from studies regarding the strengthening and tightening of the ITCZ due to anthropogenic climate change. Equatorial Low Pressure Belt or Doldrums. At which point are the doldrums located? In the Age of Sail, to find oneself becalmed in this region in a hot and muggy climate could mean death when wind was the only effective way to propel ships across the ocean. Variation in the location of the intertropical convergence zone drastically affects rainfall in many equatorial nations, resulting in the wet and dry seasons of the tropics rather than the cold and warm seasons of higher latitudes. The doldrums, usually located between 5 north and 5 south of the equator, are also known as the Intertropical Convergence Zone or ITCZ for short. Select the correct responses to the questions from the drop-down menus. The Doldrums is a low pressure area from 5N to 5S of the Equator. Answers. Solution(By Examveda Team) Doldrums are Low pressure belt of calm and light surface winds near the Equator. This band of windless, hot, and humid weather near the equator could stall sailing ships for weeks, driving the crew to distraction with the monotony and sometimes even leading to the onset of scurvy as fresh supplies ran out. Select two options. However, simulations in Coupled Model Intercomparison Project Phase 6 (CMIP6) have shown greater agreement over some regional shifts of the ITCZ in response to anthropogenic climate change, including a northward displacement over the Indian Ocean and eastern Africa and a southward displacement over the eastern Pacific and Atlantic oceans.[18]. Explanation: The doldrums are an area characterized by calm monotonous weather. Sometimes, a double ITCZ forms, with one located north and another south of the Equator, one of which is usually stronger than the other.
