In what direction do global winds and currents flow near the equator?
In the Northern Hemisphere, for example, predictable winds called trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect—a force that results from the rotation of the Earth—deflects them.
What direction do ocean currents move at the equator?
Wind or water that travels toward the poles from the equator is deflected to the east, while wind or water that travels toward the equator from the poles gets bent to the west. The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere.
In which direction do the global winds circulate?
Generally, prevailing winds blow east-west rather than north-south. This happens because Earth's rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
What direction do currents flow in the Southern Hemisphere?
Because of the Coriolis force, the major ocean currents in the northern hemisphere tend to spiral clockwise and they tend to spiral counter-clockwise in the southern hemisphere.
Why do equatorial currents flow west?
The equatorial countercurrents are driven by a distinct surface wind pattern in the tropics. Strong westward trade winds result in westward surface flow in most of the tropical Atlantic and Pacific Oceans.
Which direction do winds and currents move in the Northern Hemisphere?
Currents Tutorial Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.
What wind blows near the equator?
The trade winds are air currents closer to Earth's surface that blow from east to west near the equator. The trade winds have been used by sailors for centuries.
What happens to global winds at the equator?
The air moving back toward the equator forms warm, steady winds, known as the trade winds. The rising air at the equatorial regions and the sinking air at about 30°N and 30°S form huge convection current, known as a Hadley cell for the English meteorologist who first proposed their existence to explain the trade winds.
What are the wind systems south of the equator called?
The trade winds are winds that reliably blow east to west just north and south of the equator.
Does current flow from north to south?
An electric current flows in a wire from north to south.
Is the direction of current is always from north to south?
Direction of current is from north to south, the conductor is above the magnet-south pole of the magnet will be deflected towards west. Direction of current is from south to north, the conductor is below the magnet-south pole of the magnet will be deflected towards west.
What causes north and south equatorial currents?
Trade winds drive both North and South Equatorial Currents westward, thus transporting warm ocean-surface waters in that direction. Equatorial Counter Currents and Equatorial Under Currents return some warm waters eastward.
In what direction do the surface currents move immediately north and south of the equator in the Pacific?
A large system of circular ocean currents formed by global wind patterns and forces created by Earth's rotation. In the Northern Hemisphere, ocean currents are deflected to the right, in a clockwise motion. In the Southern Hemisphere, ocean currents are pushed to the left, in a counterclockwise motion.
What direction do the winds of a high pressure system move in the Southern Hemisphere?
The net result of the Coriolis force is that in the southern hemisphere, winds around low pressure systems or cyclones move clockwise and winds around high pressure systems or anticyclones move anticlockwise.
What will happen to the air from the south of the equator?
But because Earth is spinning, the air that moves north and south from the equator also turns with the spin of the Earth. Air going north turns to the right. Air traveling south turns to the left. The power of Earth's spin to turn flowing air is known as the Coriolis Effect.
Is there wind at the equator?
Right at the equator there is almost no wind at all—an area sometimes called the doldrums.
What winds are at the equator?
The air moving back toward the equator forms warm, steady winds, known as the trade winds. The rising air at the equatorial regions and the sinking air at about 30°N and 30°S form huge convection current, known as a Hadley cell for the English meteorologist who first proposed their existence to explain the trade winds.
Which direction does the current flow?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
When current is flowing from east to west?
Maxwell's right hand thumb rule states that, when the current flows from east to west direction, the magnetic field will move in a clockwise direction, that is, from the direction north to south.
Does current flow from north to south or south to north?
An Electric Current Flows in a Wire from North to South.
Which direction does current flow?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
What type of current is the South Equatorial Current?
The South Equatorial Current (SEC) is a broad, westward flowing current that extends from the surface to a nominal depth of 100 m.
Which direction do currents move across the equator both north and south?
Which direction do currents move across the equator both north and south? What direction does the counter current flow? hemisphere it would travel counter clockwise and for the Southern it would travel clockwise.
In what direction do winds circulate around highs in the Southern Hemisphere in what direction do winds circulate around lows in the Southern Hemisphere?
In the Southern Hemisphere, winds blow around a high pressure in an anticlockwise direction and around a low pressure in a clockwise direction.
How does the air at the equator move?
In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north. Air that rose just south of the equator flows south.
What is the direction of deflection in the Southern Hemisphere?
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.
What are the 2 direction of current flow?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
What is the direction of magnetic field when current flows from south to north?
Similarly, when the current flows from west to east direction, the magnetic field will move in an anti-clockwise direction, that is, from the direction south to north. As the direction of the magnetic field at a point above the conductor will be towards the east, for the current flow in a conductor from east to west.
What is the direction of magnetic field if current flows from east to west?
clockwise When current travels from east to west, the magnetic field moves clockwise, from north to south, according to Maxwell's right hand thumb rule.
Does current flow from south to north pole?
If in a straight conductor, the current flows from north pole to south pole.
