The Doldrums is a low pressure area from 5N to 5S of the Equator. The location of the ITCZ gradually varies with the seasons, roughly corresponding with the location of the thermal equator. The ITCZ usually lies at or near the meteorological equator also called the doldrums. The Intertropical Convergence Zone (ITCZ /t/ ITCH),[1] known by sailors as the doldrums[2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It has a bit of a reputation. Within the ITCZ the average winds are slight, unlike the zones north and south of the equator where the trade winds feed. For centuries sailors dreaded the aptly named Doldrums. Intertropical Convergence Zone | "The Doldrums" by Sailors! The region is also known as the Calms of Cancer in the northern hemisphere and the Calms of Capricorn in the southern hemisphere. For instance, when the ITCZ is situated north of the Equator, the southeast trade wind changes to a southwest wind as it crosses the Equator. Due to intense solar heating near the equator, the warm, moist air is forced up into the atmosphere like a hot air balloon. And millions of other answers 4U without ads. 3) (-2, -1) Meeting ID: 892 2837 1798 Named from their ability to quickly propel trading ships across the ocean, the trade winds between about 30 latitude and the equator are steady and blow about 11 to 13 miles per hour.

Longer term changes in the intertropical convergence zone can result in severe droughts or flooding in nearby areas. Rosenberg, Matt. Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974. 3. Surges of higher pressure from high latitudes can enhance tropical disturbances along its axis. [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. The ITCZ is commonly defined as an equatorial zone where the trade winds converge. This NASA satellite image shows the Inter-Tropical Convergence Zone, known to sailors around the world as the doldrums. [12] In the north Atlantic and the northeastern Pacific oceans, tropical waves move along the axis of the ITCZ causing an increase in thunderstorm activity, and clusters of thunderstorms can develop under weak vertical wind shear. This was a particular problem for sailors in the past when they depended on the winds to propel their ships, a problem that could be potentially deadly. trade winds. [4] The ITCZ is effectively a tracer of the ascending branch of the Hadley cell and is wet. Share sensitive information only on official, secure websites. Lau. A small lock or https:// means youve safely connected to a .gov website. the cells uses some of the atoms of the glucose molecules to atp molecules. A .gov website belongs to an official government organization in the United States. Air moves in a direction that creates land breezes. [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). trade winds. [13] The aircraft crashed with no survivors while flying through a series of large ITCZ thunderstorms, and ice forming rapidly on airspeed sensors was the precipitating cause for a cascade of human errors which ultimately doomed the flight. This belt is also called the Doldrums, because of the extremely calm air movements. if the egg is not fertilized, the corpus luteum becomes inactive after 1014 days, and menstruation occurs. The ITCZ has also undergone periods of contraction and expansion within the last millennium. Which blow over long distances?-trade winds-local winds-land breezes-sea breezes-trade winds.

Select the correct responses to the questions from the drop-down menus. As the heat capacity of the oceans is greater than air over land, migration is more prominent over land. This website is not intended for users located within the European Economic Area. During Heinrich events within the last 100ka, a southward shift of the ITCZ coincided with the intensification of the Northern Hemisphere Hadley cell coincident with weakening of the Southern Hemisphere Hadley cell. This heating causes the air to warm and rise straight up rather than blow horizontally. 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.
