The ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone (ITCZ / ɪ tʃ / ITCH, or ICZ), [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.
Approximately 1,500–5,000 hot towers daily near the ITCZ region are required to sustain the vertical heat transport exhibited by the Hadley circulation. [23] The ascent of air rises into the upper troposphere to a height of 12–15 km (7.5–9.3 mi), after which air diverges outward from the ITCZ and towards the poles. [24]
At 345 feet (105 m) above mean sea level, Britton Hill in northern Walton County is the highest point in Florida and the lowest known highpoint of any U.S. state. [3] Much of the state south of Orlando is low-lying and fairly level; however, some places, such as Clearwater, feature vistas that rise 50 to 100 feet (15 to 30 m) above the water.
The ITCZ would be expected to overlie the geographic equator according to symmetric solar radiation. [1] However, the ITCZ is mostly perennial in the northern hemisphere and in the eastern Pacific and Atlantic Oceans. [2] [3] It was originally explained by the asymmetrical distribution of continents.
February position of the ITCZ and monsoon trough in the Pacific Ocean, depicted by area of convergent streamlines offshore Australia and in the equatorial eastern Pacific. Monsoon troughing in the western Pacific reaches its zenith in latitude during the late summer when the wintertime surface ridge in the opposite hemisphere is the strongest.
Maps show the areas impacted by storm surge, rainfall levels and more as Helene, once a major hurricane and now a tropical storm, moves inland from Florida's Gulf Coast over Georgia.
When Hurricane Helene battered Florida’s Gulf Coast this week, one of the hardest-hit areas was the small town of Steinhatchee, which was overwhelmed by a 10-foot storm surge and 140 mph winds ...
At the surface, the current is located on the southern slope of the North Equatorial Trough, a region of low sea level which extends from east to west across the Pacific. The low sea level is a result of Ekman suction caused by the increased easterly winds found just to the north of the Intertropical Convergence Zone (ITCZ).
