Quick Answer: What Drives Weather And Ocean Circulation?

What are the two main factors that affect deep ocean currents?

Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy.

Water density is affected by the temperature, salinity (saltiness), and depth of the water.

The colder and saltier the ocean water, the denser it is..

What are 2 types of ocean currents?

There are two type of Ocean Currents:Surface Currents–Surface Circulation.Deep Water Currents–Thermohaline Circulation.Primary Forces–start the water moving.The primary forces are:Secondary Forces–influence where the currents flow.Solar heating cause water to expand.More items…

What are the two main reasons for the development of ocean currents?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.

What are the 5 major ocean currents?

There are five main gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.

How do oceans affect climate?

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …

What is the ocean current called?

Thermohaline circulation, also known as the ocean’s conveyor belt, refers to the deep ocean density-driven ocean basin currents. … These currents, which flow under the surface of the ocean and are thus hidden from immediate detection, are called submarine rivers.

What is thermohaline circulation?

thermohaline circulationThermohaline circulation transports and mixes the water of the oceans. In the process it transports heat, which influences regional climate patterns. The density of seawater is determined by the temperature and salinity of a volume of seawater at a particular location.

What drives deep ocean circulation?

Winds drive ocean currents in the upper 100 meters of the ocean’s surface. … These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

What drives the circulation of the ocean and air on Earth?

Global Ocean Circulation. Ocean circulation is the large scale movement of waters in the ocean basins. Winds drive surface circulation, and the cooling and sinking of waters in the polar regions drive deep circulation. … Heat is disbursed along the way from the waters to the atmosphere.

What are the 3 types of ocean currents?

Types of Water CurrentsSurface Currents. Surface currents occur in the upper 400 meters of the ocean. … Deep Water Currents. Deep water currents make up 90 percent of the ocean currents. … Why Currents Are Important.

How does ocean circulation affect weather?

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. … The ocean doesn’t just store solar radiation; it also helps to distribute heat around the globe.

Which zone of the ocean is the warmest?

epipelagic zoneThe epipelagic zone tends to be the warmest layer of the ocean.

What are 5 factors that affect current flow?

There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors (temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors (atmospheric pressure, winds, rainfall, evaporation and insolation); factors that …

What would happen if ocean circulation stopped?

If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
