What is influenced by the Coriolis effect?
the result of Earth's rotation on weather patterns and ocean currents. The Coriolis effect makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.
The Coriolis effect is important to virtually all sciences that relate to Earth and planetary motions. It is critical to the dynamics of the atmosphere including the motions of winds and storms. In oceanography , it helps explains the motions of oceanic currents.
- Energy from the wind is quickly dissipated, so wind-driven currents slow down with depth, and finally die out within a few hundred meters of the surface. Surface currents are also triggered by gravity. Instead, the currents move at an angle to the force that generates them–a phenomenon called the Coriolis effect.
- The Coriolis Effect. The rotation of the Earth causes an interesting phenomenon on free moving objects on the Earth. Objects in the Northern Hemisphere are deflected to the right, while objects in the Southern Hemisphere are deflected to the left. The coriolis effect and pressure gradient work against each other.
- One can find both counterclockwise and clockwise flowing drains in both hemispheres. Some people would like you to believe that the Coriolis force affects the flow of water down the drain in sinks, bathtubs, or toilet bowls. Don't believe them! The Coriolis force is caused by the earth's rotation.
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. Click the image for a larger view. Coastal currents are affected by local winds.

- The Coriolis effect is the one that makes low pressures rotate anti-clockwise in the northern hemisphere and clockwise in the southern. At the equator, the forces cancel each other out. That's why the direction of rotation changes between the two hemispheres.
- Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.
The Coriolis Effect can be seen in action in the general circulation of the atmosphere. The winds at all latitudes to the north of 0° deflect to the right of their intended path in the Northern Hemisphere. The Coriolis Effect does not impact the wind speed, only the wind direction.
- Winds near the surface: Winds affected by friction. Geostrophic wind blows parallel to the isobars because the Coriolis force and pressure gradient force are in balance. For example, a calm ocean surface is pretty smooth, so the wind blowing over it does not move up, down, and around any features.
- When a classic El Niño episode occurs, the trade winds experience a brutal drop in force, and the upwelling(4) phenomenon that is triggered all around the equator by the Coriolis effect slows down. The huge reservoir spreads out into the Pacific towards the east and the water becomes depleted.
- Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.
