The Atlantic meridional overturning circulation ( AMOC) is the main ocean current system in the Atlantic Ocean. [ 1]: 2238 It is a component of Earth's ocean circulation system and plays an important role in the climate system. The AMOC includes Atlantic currents at the surface and at great depths that are driven by changes in weather ...
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
Loop Current. A parent to the Florida Current, the Loop Current is a warm ocean current that flows northward between Cuba and the Yucatán Peninsula, moves north into the Gulf of Mexico, loops east and south before exiting to the east through the Florida Straits and joining the Gulf Stream. The Loop Current is an extension of the western ...
Scientists do know — from building a picture of the past using things like ice cores and ocean sediments — the AMOC shut down more than 12,000 years ago following rapid glacier melt.
The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [ 2] It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas ( North America and South ...
Thermohaline circulation ( THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [1] [2] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water.
The 1991 Perfect Storm, also known as The No-Name Storm (especially in the years immediately after it took place) [ 1] and the Halloween Gale/Storm, was a damaging and deadly nor'easter in October 1991. Initially an extratropical cyclone, the storm absorbed Hurricane Grace to its south and evolved into a small unnamed hurricane later in its life.
The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS ) to higher-than-usual levels of ionizing ...
