What does the Ekman spiral predict?
In the Northern Hemisphere, the Ekman spiral predicts net water movement through a depth of about 100 to 150 m (330 to 500 ft) at 90 degrees to the wind direction (Figure B). That is, if one adds up all the vectors in (Figure A), the resulting flow is at 90 degrees to the right of the wind direction.
What happened to the Styrofoam cup that was subjected to the high pressure of the deep ocean quizlet?
What happened to the Styrofoam cup that was subjected to the high pressure of the deep ocean? It became a miniature-sized cup.
What is the Ekman transport in simple terms?
Ekman transport is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. In the picture above, the wind blowing North in the northern hemisphere creates a surface stress and a resulting Ekman spiral is found below it in the water column.
What are the main forces that cause Ekman transport?
An Ekman spiral (A) is a rotating column of water that forms when water moves at an angle to the wind direction due to the Coriolis Effect. The net effect of the rotating water (B) is movement at a right angle to the wind direction.
What is Ekman spiral in oceanography?
The Ekman spiral, named after Swedish scientist Vagn Walfrid Ekman (1874-1954) who first theorized it in 1902, is a consequence of the Coriolis effect. When surface water molecules move by the force of the wind, they, in turn, drag deeper layers of water molecules below them.
What is the Ekman spiral and how does this phenomenon result in the production of a hill of water located in the western Atlantic ocean?
1 The Ekman spiral, shown for the Northern Hemisphere. Wind blowing over the water (blue arrow) creates a surface current 45o offset from the wind. Each successive layer of water is moved and deflected by the layer above, creating a spiraling pattern of water movement that diminishes with depth.
What would you expect weather to be like on the eastern coast of Australia if the western coast of South America were experiencing unusually warm wet weather?
What would you expect weather to be like on the eastern coast of Australia if the western coast of South America were experiencing unusually warm, wet weather? The eastern coast of Australia would be experiencing unusually dry weather.
Why are electrical outputs from a turbine generator highest during a spring tide quizlet?
Why are electrical outputs from a turbine generator highest during a spring tide? – A high tide comes in faster. – The gravitational pull of the moon is less.

What term describes the large scale weather phenomenon that occurs when prevailing winds in the Pacific ocean weaken resulting in above average warming?
El Niño Events El Niño events are defined by their wide-ranging teleconnections. Teleconnections are large-scale, long-lasting climate anomalies or patterns that are related to each other and can affect much of the globe. During an El Niño event, westward-blowing trade winds weaken along the Equator.
Which of the following phenomena occur in the tropical South Pacific Ocean during ENSO quizlet?
Which of the following phenomena occur in the tropical South Pacific Ocean during ENSO? A low-pressure system forms over the eastern South Pacific and upwelling of colder ocean water slows down near the South American coast.
Which factor drives surface ocean currents or wind energy solar energy pull of the moon movement of turbines?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
How does convection move heat in the ocean during non El Niño years?
Ocean circulation is the large-scale movement of water in the ocean. It involves the transport of heat through convection, which is the movement of heat through liquids and gases. Which statement describes how convection moves heat in the ocean during non-El Niño (normal) years? – Convection moves heat toward the west.
Where does Ekman move water?
In coastal areas where prevailing winds blow along the coast, Ekman transport causes surface water to flow offshore. This movement of water away from the coast at the surface causes deeper water to upwell. This upwelled water tends to be rich in nutrients, making coastal upwelling zones highly productive areas.
Which of these is commonly an effect of El Niño?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What is the most important factor in determining which biome is found in a particular area?
Climate Climate is the main factor is determining which plants can grow in a certain area, which in turn defines the biome.
How is the El Niño phenomenon connected with the Southern Oscillation Class 9?
The Southern Oscillation is a change in air pressure over the tropical Pacific Ocean. When coastal waters become warmer in the eastern tropical Pacific (El Niño), the atmospheric pressure above the ocean decreases. Climatologists define these linked phenomena as El Niño-Southern Oscillation (ENSO).
Which of these is commonly an effect of El Niño quizlet?
El Nino Southern Oscillation, trade winds weaken & warm surface water moves toward South America. Diminished fisheries off South America, drought in western Pacific, increased precipitation in southwestern North America, fewer Atlantic hurricanes.
Which source provides the energy that causes most waves to form currents earthquakes sunlight wind?
The Sun as a Source of Energy for Winds, Currents & the Water Cycle.
What turbine is used in tidal energy?
Kaplan turbine Which type of turbine is commonly used in tidal energy? Explanation: The Kaplan turbine is a propeller type reaction turbine that is usually immersed completely in the fluid it derives energy from.
Which global circulation is influenced by ENSO events what type of event occurs when it intensifies?
El Niño influences global atmospheric circulation by intensifying the Hadley circulation, in which heat is transferred from the Earth's surface to the upper atmosphere through convection and latent heating.
What effect does the El Nino Southern Oscillation ENSO have on water supplies to the Colorado River basin?
While El Niño-Southern Oscillation (ENSO) strongly influences precipitation in the lower basin, its influence on the upper basin snowpacks is much weaker, so ENSO's overall effect on streamflow in the Colorado River basin is modest, except during very strong El Niño events.
What forms of technology are scientists using to study El Niño?
What forms of technology are scientists using to study El Niño? Scientists have placed buoys at the bottom of the ocean and they take measurements on the ocean temperature, the wind temperature, etc. If and when they start to notice a change they can predict El Nino might be coming. Scientists can also use satellites.
Which factors are most important in determining the distribution of biomes around the world and why?
Explanation: The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.
Which two factors are most important in determining the type of biome that develops in a given area of ocean?
Answer and Explanation: The two main factors that determine a particular biome are temperature and precipitation, or the climate of the region.
What do you mean by El Nino Southern Oscillation how it’s affected monsoon of India discuss?
The El Nino weather phenomena is gaining strength. Later global forecasts indicate potentially affecting the south west from June to September monsoon of India. El Nino, characterized by warming of surface temperatures in the Pacific Ocean, is associated with lower than normal monsoon rainfall in India.
