The latitude preference of the intertropical convergence zone (ITCZ) is examined on the basis of observations, theory, and a modeling analysis. The Inter-Tropical Convergence Zone (ITCZ - pronounced "itch") appears as a band of clouds consisting of showers, with occasional thunderstorms, that encircles the globe near the equator. Q 18. Early mariners called this region the Between about 30° to 35° north and 30° to 35° south of the equator lies the region known as the horse latitudes or the subtropical high. As it moves towards the mid-latitudes on both sides of the equator, the air cools and sinks. The Intertropical Convergence Zone is also known as the Equatorial Convergence Zone or Intertropical Front. The Intertropical Convergence Zone, or ITCZ, is a band of low pressure around the Earth which generally lies near to the equator. Horse Latitudes . In contrast, during a previous study in the region (October– November 2005; Atlantic Meridional Transect [AMT-17]; ref. Related questions. Aided by the convergence of the trade winds, the buoyant air rises. intertropical convergence zone (ITCZ, equatorial trough) Low-latitude zone of convergence between air masses coming from either hemisphere at the boundary between north-easterly and south-easterly trade winds. This air mass rises to the lower stratosphere where it diverges, moving away from the equator in the upper troposphere in both northerly and southerly directions. Intertropical Convergence Zone. The air rises so that it cools and condenses to create clouds and rain. The Cariaco Basin, located on the northern margin of Venezuela, is sensitive to tropical Atlantic climate change and its sediments provide a record of past ITCZ behavior. The intertropical convergence zone (ITCZ) has been the focus of considerable research in recent years, with much of this work concerned with how the latitude of maximum tropical precipitation responds to natural climate variability and to radiative forcing. • The Intertropical Convergence Zone, which is determined by the season/tilt of the earth Winds Weather in the tropics is essentially a phenomenon of solar radiation and air circulation, along with deviations caused by the earth’s rotation. It is characterised by convective activity which generates often vigorous thunderstorms over large areas. intertropical convergence zone n. A 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. Explore answers and all related questions . (ITCZ,Low-latitude zone of convergence between air masses coming from either hemisphere at the boundary between north-easterly and south-easterly trade winds. Warm, humid air that converges here rises and cools, forming clouds and frequent, heavy showers. The trade winds of the northern and southern hemispheres come together here, which leads to the development of frequent thunderstorms and heavy rain. Observations show that convection is enhanced at latitudes of about 4° to 10° relative to the equator, even in regions where the sea surface temperature (SST) is maximum on the equator. spacing of isobars on a weather map. Saturday 11/16 Monday 11/18 Wednesday 11/20 Saturday 11/23 (2) Ascent of air parcels can be forced by atmospheric motions associated with mid ‐ latitude fronts and depressions. Its position is largely controlled by hemisphere temperature contrasts1, 2. The dynamics of the Intertropical Convergence Zone has a significant role in changing the characteristics of the Indian monsoon rainfall Since 2002, the … Observational analysis indicates that a dynamical mechanism in the atmosphere is acting to position the ITCZ(s) away from the equator to latitudes of about 4-10^circ, even in regions where the SST is maximum on the equator. the Equator . The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments. D) Maghreb. This region of subsiding dry air and high pressure results in weak winds. Intertropical Convergence Zone (ITCZ) The ITCZ is a zone of convergence at the thermal equator where the trade winds meet. The position of the intertropical convergence zone is an important control on the distribution of low-latitude precipitation. Wind speed may be roughly indicated by. Intertropical Convergence Zone produces inflow and outflow at many levels: −15 −10 −5 0 5 10 15 2 4 6 8 10 12 14 16 latitude z (km) Mean V (m/s) max=5.97e+00 min=−5.81e+00 int=5.00e−01 −6 −4 −2 0 2 4 6 shallow return flow (SRF) boundary layer inflow (BLI) mid-level inflow (MLI) upper level outflow (ULO) SST maximum. The cloud band, at times, is narrow (2 to 3 degrees latitude) and continuous for thousands of miles. C) near the equator. The Inter Tropical Convergence Zone (ITCZ) is a low pressure zone located at the equator where trade winds converge (being a low pressure zone), and so, it is a zone where air tends to ascend. Horizontal winds are are often light to calm, making it difficult to sail at the ITCZ. latitude imposed ice (land or sea) influence on the marine Intertropical Convergence Zone (ITCZ) in the Community Climate Model version 3 coupled to a 50-m slab ocean. It exists because of the convergence of the trade winds. Heating of the earth near the equator leads to large amounts of convection along the monsoon trough or Intertropical convergence zone. The location of the ITCZ can vary as much as 40° to 45° of latitude north or south of the equator based on the pattern of land and ocean. B) Kalahari. B) near the Tropic of Capricorn. density. The Intertropical Convergence Zone (ITCZ) is the low pressure area near the equator in the boundary between the two Hadley Cells. On occasion, vertical cloud patterns are observed within the ITCZ cloud band. Revisiting the latitude fluctuations of the eastern Pacific ITCZ during the central Pacific El Niño Ruihuang Xie1 and Yuxing Yang1 1Key Laboratory of Ocean Circulation and Waves, Institute of Oceanology, Chinese Academy of Sciences, Qingdao, Shandong, China Abstract Some previous studies have reported that the Intertropical Convergence Zone (ITCZ) in the Its in the vicinity of Dakar (Dakar latitude is 14.6 deg N). D) in South Africa,Swaziland,and Lesotho. The Rossby waves. Africa is split in two by the equator and most of the continent is within the tropic zone with small sections of the north and south in the temperate zones (the continental range is about 35°N to 35°S latitude). Intense heat at the equator puts air in motion, and a worldwide pattern of winds is established. This warm air rises to the top of the troposphere, and spreads out toward the Northern and Southern Hemispheres. dust by the InterTropical Convergence Zone (ITCZ), which had its core at ∼1°N during our cruise period, close to the southern-most latitude reached during its annual migration (40, 41) (Fig. The inter-tropical convergence zone (ITCZ) particularly affects, western Africa between 10 and 20 deg N and the northern coasts of the Arabian sea in July. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant. High rainfall in the equatorial latitudes associated with the strong convection in the ITCZ. Changes in the strength and position of the Intertropical Convergence Zone (ITCZ) are an important component of climate variability in the tropical Atlantic. Here, the prevailing trade winds of the northern hemisphere blow to the southwest and collide with the southern hemisphere’s driving … Climate along the ITCZ is therefore warm and wet. The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. 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. C) Ethiopian Highlands. Widespread uplifting gives extended periods of gentle rain over a broad area. Regarding the movement of the ITCZ in the region of West Africa: It reaches its maximum northerly position of 15 to 20 deg N in July. The rain produced by the intertropical convergence zone is most abundant: A) near the Tropic of Cancer. The warmer air near the equator rises and creates a region of heavy rain and thunderstorms called the Intertropical Convergence Zone (ITCZ), or the Doldrums. The latitude preference of the Intertropical Convergence Zone (ITCZ) is examined on the basis of observations, theory, and a modeling analysis. The southern fringes of the Sahara Desert are known as the: A) Sahel. At other times, it is discontinuous and is characterized by a number of large cloud areas 5 to 10 degrees in latitude across. 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. ITCZ: Intertropical Convergence Zone. In Africa, the ITCZ is located just south of the Shale at about 10°, dumping rain on the region to the south of the desert. Using the attached blank circle which represents the Earth, Label the special latitudes: Mark the special latitudes (one in each hemisphere) where the air is sinking with an H on the latitude line, and where the air is rising, mark the latitude line with an L. Label each latitude as either the Intertropical Convergence Zone or Subtropical High-Pressure Zone (one in each hemisphere). Which of the below is located in the troposphere above the polar front? 1 B). The pressure of a gas is proportional to its temperature and.
