The Intertropical Convergence Zone, known by sailors as doldrums or “the calms” due to the dull, windless weather, is the area where the northeast and southeast trade winds converge. The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. This phenomenon happens around June 20th when the sun is overhead the Tropic of Cancer at 23½ degrees North and around December 20th when the sun is overhead the Tropic of Capricorn at 23½ degrees south. Different places receive varying heat energy amounts as the earth rotates with the seasons. The Intertropical Convergence Zone (ITCZ), which is the heaviest rain belt on Earth, significantly influences global hydroclimate change and livelihood of nearly 40% of the global population. As the air rises, the moisture within it condenses, clouds form and it rains. The Intertropical Convergence Zone, or ITCZ, is a band of low pressure around the Earth which generally lies near to the equator. The trade winds meet (or converge) in the zone of low pressure in equatorial regions. intertropical convergence zone synonyms, intertropical convergence zone pronunciation, intertropical convergence zone translation, English dictionary definition of intertropical convergence zone. It is also called Equatorial Convergence Zone (ECZ) or Intertropical Front. Over the Indian Ocean, it undergoes especially large seasonal shifts of 40°–45° of latitude. Here, we consider the response of the ITCZ structure to climate change using observations, simulations, and theory. They will understand that the Intertropical Convergence Zone is only a part of a larger air circulation system that is the cause for the climate zones between the Tropics and the Subtropics. Corrections? 16.11.2018. It encircles Earth near the thermal equator, though its specific position varies seasonally.

Intertropical convergence zone (ITCZ), also called equatorial convergence zone, belt of converging trade winds and rising air that encircles the Earth near the Equator. The ITCZ (Intertropical Convergence Zone) play important role in the global circulation system and also known as the Equatorial Convergence Zone or Intertropical Front. A migrating zone of unstable atmospheric conditions…. It encircles Earth near the thermal equator, though its specific position varies seasonally. The belt is mostly characterized by vigorous thunderstorms over broad areas due to convective activity. This movement can result into a complete reversal of regular trade winds, especially in the Indian Ocean. The rising air produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions of calm surface air, occur within the zone. intertropical convergence zone (ITCZ) zone of convergence of air masses along the equatorial trough subtropical high-pressure belt belt of persistent high atmospheric pressure centered approximately on latitudes 30 degrees N and 30 degrees S trade winds easterly winds found in the tropical regions north and south of the Equator +36 more terms Since the air in this belt keeps rising frequently, it condenses in the atmosphere to form clouds. It encircles Earth near the thermal equator, though its specific position varies seasonally.When it lies near the geographic Equator, it is called the near-equatorial trough. https://www.britannica.com/science/intertropical-convergence-zone. Atmospheric conditions in the ITCZ are very unstable. THE BRIEF. The cause and impact of the Intertropical Convergence Zone. The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums or the calms because of its monotonous, windless weather, is the area where the northeast and southeast trade winds converge. By Nigel Amaya on May 23 2018 in World Facts. controls river currents has large petroleum deposits influences climate is a hydroelectric plant The Intertropical Convergence Zone influences climate. Due to the storms collected in this area, it makes it hard for aircraft to fly over the zone and also for a ship to sail through. The zone appears as a band of clouds, usually, thunderstorms, circling the globe near the Equator. climate zones between the tropics and the subtropics. Navigate parenthood with the help of the Raising Curious Learners podcast. We focus on the substantial yet underappreciated projected changes in ITCZ width and strength, and highlight an emerging conceptual framework for … It follows the appar-ent annual path of the Sun northward and southward during the seasons. An example is an aircraft, Air of France Flight 447 which crashed with no survivors in the region due to thunderstorms. 1 a). The double-Intertropical Convergence Zone (ITCZ) problem, in which excessive precipitation is produced in the Southern Hemisphere tropics, which resembles a Southern Hemisphere counterpart to the strong Northern Hemisphere ITCZ, is perhaps the most significant and most persistent bias of global climate models. The rising air produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions of calm surface air, occur within the zone. intertropical convergence zone definition: nounA broad area of low atmospheric pressure where the northeasterly and southeasterly trade winds converge over the equatorial region, extending approximately 10° north and south of the equator. The trade winds of the northern and southern hemispheres come together here, which leads to the development of frequent thunderstorms and heavy rain. controls river currents has large petroleum deposits influences climate is a hydroelectric plant The Intertropical Convergence Zone influences climate. jəns ‚zōn] (meteorology) The axis, or a portion thereof, of the broad trade-wind current of the tropics; this axis is the dividing line between the southeast trades and the northeast trades (of the Southern and Northern hemispheres, respectively). The ITCZ itself is a belt of low pressure that circles the Earth, generally near the Equator. The unstable conditions in the ITCZ make equatorial regions some of the wettest in the world. The intertropical convergence zone (ITCZ) is one of the most important components of the climate system. Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. The ITCZ is a zone of convergence at the thermal equator. Similar migrations of the intertropical convergence zone have been observed in Central America for the period ad 700 to 900 (refs 4-6), suggesting … Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... …trade winds from both hemispheres converge and give rise to a general upward motion of air, which becomes intensified locally in tropical storms that produce very heavy rains in the Caribbean, the Indian and southwest Pacific oceans, and the China Sea and in thunderstorms that are especially frequent and active…, …the region known as the intertropical convergence zone (ITCZ).…, The ITCZ is responsible for the seasonal character of precipitation in South America’s extensive tropical wet-dry climatic zone. The intertropical convergence zone (ITCZ) is the world’s most important rainfall belt, affecting the livelihood of billions of people globally. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The heat from the ocean currents makes the air warm at the Earth’s surface creating a region of low pressure. The northern and the southern trade winds converge at the ITCZ and to due to Earth’s rotation, the winds lose energy as they cross the equator. Because the ITCZ is a zone of high precipitation, we suggest that this convergence was an important driver of Early Miocene High Himalayan exhumation and erosion. Since ecosystems are dependent mainly on weather patterns and temperature, shifts in weather affect animal and plant life directly or indirectly. It is a low pressure belt and migrates with the changing position of the thermal equator. The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums or the calms because of its monotonous, windless weather, is the area where the northeast and southeast trade winds converge. Also known as … This area is the intertropical convergence zone (ITCZ). The teacher starts off with some introductory remarks. The ITCZ shifts north and south seasonally with the Sun. The ITCZ is also called the "climate equator"—it lies near the geographic equator, and divides the global air circulation patterns into two mirror images to the north and south. The belt receives afternoon showers due to high humidity.
