Downwelling is a crucial process in thermohaline circulation, as it occurs when dense, cold, and salty water sinks into the ocean depths, particularly in polar regions. This sinking water drives the global conveyor belt of ocean currents, facilitating the transport of heat and nutrients across the world's oceans. As downwelling occurs, it helps regulate climate by redistributing warm and cold water, influencing weather patterns and marine ecosystems. Ultimately, downwelling is a key mechanism that maintains the balance of oceanic circulation and global climate systems.
What else can I help you with?
What forces dive deep ocean currents?
Deep ocean currents are primarily driven by two main forces: thermohaline circulation and wind. Thermohaline circulation is influenced by variations in water density, which is affected by temperature (thermo) and salinity (haline). As surface water cools and becomes saltier, it sinks, creating a global conveyor belt of deep ocean currents. Additionally, wind-driven surface currents can also influence deeper currents through the process of upwelling and downwelling.
What causes thermohaline circulation?
The term thermohaline circulation ( THC ) refers to the part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes
What is another name for thermohaline?
Another name for thermohaline circulation is the ocean conveyor belt. This circulation pattern involves the movement of water around the world's oceans based on differences in temperature and salinity.
What two characteristics of water combine to form a thermohaline?
The two characteristics of water that combine to form a thermohaline current are temperature and salinity. As water becomes cold and more saline, it becomes denser and sinks to the ocean floor, driving the vertical circulation of the ocean known as the thermohaline circulation.
Thermohaline circulation is driven by changes in?
Thermohaline circulation is driven by changes in temperature and salinity of ocean water. Cold, dense water sinks in the polar regions due to its high salinity and low temperature, driving the deep ocean currents that help regulate the global climate by redistributing heat and nutrients around the world.
How does salinity and temperature effect thermohaline circulation?
Salinity affects thermohaline circulation by influencing the density of seawater. Higher salinity increases water density, promoting sinking of cold, dense water in polar regions. Temperature influences this circulation by controlling the density of water - colder water is denser and more likely to sink. Both factors work together to drive the global thermohaline circulation system.
Surface ocean circulation is also called thermohaline circulation?
Thermohaline circulation is also called overturning circulation. It is driven by density. The time scale for thermohaine is 1000 years.
How can thermohaline circulation regulate climate?
It is gravity that drives thermohaline circulation. It's a gravity current. We usually apply the term thermohaline circulation to the deep ocean currents that are driven by gravity. Colder water or water that has a higher salt content than other water is more dense, and gravity will act on it to pull it "down" deeper. It will displace warmer or less salty water and move to greater depths. This sets the stage for a deep ocean current we call a thermohaline expressway. Use the links below for more information on gravity currents (which are sometimes called density currents)._______________________sflo:I would say this answer is limited in explaining what drives thermohaline circulation. Changes in density certainly affect circulation, particularly when water emerges from the deep or submerges to depths (upwelling and downwelling), but the effects of "gravity" on water masses of varying densities aren't a driver of circulation, per se. I would like to point that within the "thermohaline circulation," "thermo-" and "haline" are both components of the name. Thus in a more elemental manner, it makes more sense to explain this phenomenon by temperature and salinity differences, as well as the resulting changes in density, rather than merely "gravity."For a great snap-shot of our current understanding (or rather lack-therof) of the thermohaline circulation, what drives it, and how it affects or is affected by climate, please look-up:"Thermohaline circulation: The current climate" Nature421, 699 (13 February 2003) | doi:10.1038/421699a == ==

A thermohaline current is a current which is affected by?
A thermohaline current is affected by differences in water temperature and salinity. These differences drive the circulation of deep ocean waters around the globe, transporting heat and nutrients to different regions and influencing climate patterns.
Which of the fllowing is caused by differences in ocean water density?
Differences in ocean water density are primarily caused by variations in temperature and salinity, leading to ocean currents. These density differences drive the global thermohaline circulation, also known as the "ocean conveyor belt," which plays a crucial role in regulating climate and distributing heat across the planet. Additionally, these differences can lead to phenomena such as upwelling and downwelling, affecting marine ecosystems.
What is the driving force of deep-ocean circulation?
The driving force of deep-ocean circulation is primarily the sinking of cold, dense water at high latitudes due to its higher density. This process is known as thermohaline circulation, where temperature and salinity differences create variations in water density, causing water masses to sink and drive the global ocean circulation.
What is thermohaline circulation?
Thermohaline circulation is a global pattern of ocean currents driven by differences in temperature and salt concentration. It plays a crucial role in distributing heat around the planet and regulating climate. This circulation helps transport nutrients and oxygen throughout the ocean, influencing marine ecosystems.
