Coriolis force Meaning and Definition

Pronunciation

/kɔːriːˈɒlɪs/ 🔊

Part of Speech

Noun

Definition

The apparent deflection of a moving object from its intended path, caused by the Earth’s rotation. In meteorology, it is responsible for the rotation of large-scale circulation patterns, such as hurricanes and typhoons.

Examples

• The Coriolis force plays a significant role in shaping global wind patterns.
• Understanding the Coriolis force is crucial for predicting hurricane trajectories.

Synonyms

• Apparent deflection
• Geostrophic force

Antonyms

• Centrifugal force
• Frictional force

Additional Information

The Coriolis force is a fundamental concept in meteorology and oceanography, as it helps explain the large-scale circulation patterns in the atmosphere and oceans. It is named after French mathematician Gaspard-Gustave Coriolis, who first described the phenomenon in the early 19th century. The Coriolis force is responsible for the rotation of hurricanes, typhoons, and other tropical cyclones, as well as the formation of ocean currents and the distribution of heat around the globe.

The Coriolis force is also important in the field of aviation, as it affects the trajectory of aircraft and the navigation of pilots. In addition, it plays a role in the formation of weather patterns, such as high and low-pressure systems, and the movement of weather fronts.

While the Coriolis force is often misunderstood as a force that acts on objects, it is actually an apparent deflection caused by the Earth’s rotation. This means that the Coriolis force is not a force that acts on objects, but rather a result of the Earth’s rotation and the motion of objects on its surface.

Etymology

The term “Coriolis force” was coined in the 19th century, named after French mathematician Gaspard-Gustave Coriolis, who first described the phenomenon in 1835. The word “Coriolis” is derived from the French surname “Coriolis,” which is of Italian origin.

Usage Notes

The Coriolis force is often used in meteorology and oceanography to explain large-scale circulation patterns. It is also used in aviation to navigate aircraft and predict weather patterns. In general, the Coriolis force is used to describe the apparent deflection of moving objects on the Earth’s surface.

Cultural References

The Coriolis force has been referenced in popular culture, including in films, literature, and music. For example, the film “The Day After Tomorrow” (2004) features a scene in which a character explains the Coriolis force and its role in shaping global weather patterns.
