WebMar 15, 2024 · Summary. Schematic diagram of the thermohaline circulation in the North Atlantic. In this module, students first review some background material on density-driven deep currents in the oceans, and then create a STELLA model of the thermohaline circulation in the North Atlantic Ocean. The model is based on a classic 1961 paper in … WebMay 20, 2024 · thermohaline circulation noun ocean conveyor belt system in which water moves between the cold depths and warm surface in oceans throughout the world. tide noun rise and fall of the ocean's waters, caused by the gravitational pull of the moon and sun.
WebWhen the temperature goes down, the particles in the water vibrate less, so the same number of molecules take up less space and make the water denser. Water also becomes denser when you add salt because there are more molecules in a given volume. Thermohaline Circulation transports water throughout the planet. Page 1 of 2 Earth Science WebOcean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by exchange of ocean heat and water with the …
WebMay 7, 2024 · As warm water from the tropics flows toward the poles in wind-driven currents near the surface, it cools, becoming denser and heavier, and eventually sinks. It then begins flowing back toward the... The movement of surface currents pushed by the wind is fairly intuitive. For example, the wind easily produces ripples on the surface of a pond. Thus, the deep ocean—devoid of wind—was assumed to be perfectly static by early oceanographers. However, modern instrumentation shows that current velocities in deep water masses can be significant (although much less than s…
WebThermohaline circulation describes the movement of ocean currents due to differences in temperature and salinity in different regions of water. Temperature and salinity change the density of water, resulting in the …
