INDIA: The Coriolis effect is a phenomenon that occurs due to the rotation of the earth. As the planet spins on its axis, objects on the surface of the Earth appear to move in a curved path rather than a straight line. This effect is most noticeable near the poles and is weaker near the equator.
Have you ever noticed how water drains from a bathtub or toilet in a swirling motion? Or have you ever wondered why aeroplanes travelling from east to west take longer than those travelling from west to east?
These phenomena and many others occur due to the Coriolis effect, a strange and fascinating force that has puzzled scientists and laypeople for centuries.
One of the most famous examples of the Coriolis effect is how the water drains from a bathtub or toilet.
In the northern hemisphere, water will drain clockwise, while in the southern hemisphere, it will drain anticlockwise.
This phenomenon is not due to the direction of the toilet or bathtub, but rather the Coriolis effect.
The rotation of the Earth causes the water to move in a curved path, resulting in a swirling motion.
The Coriolis effect also plays a role in the Earth’s weather patterns. The rotation of the Earth causes air masses to move in a curved path, creating high- and low-pressure systems.
These irregular pressure patterns can lead to the formation of hurricanes and other weather events.
The Coriolis effect is also responsible for the prevailing winds that blow from west to east in the mid-latitudes.
Another example of the Coriolis effect is how aeroplanes travel from east to west. Due to the rotation of the Earth, it takes longer for them to fly from east to west than from west to east.
This skewed air time is because the aeroplane is travelling against the rotation of the earth, which means that the earth is rotating beneath it.
As a result, the aeroplane has to travel a greater distance to reach its destination.
The Coriolis effect is also responsible for the rotation of the Earth itself. It is not constant and varies due to the distribution of mass on the planet.
The Coriolis effect causes the equator to bulge out slightly, which creates a torque that slows down the rotation of the earth.
This effect is negligible, but over millions of years, it can significantly impact the planet’s rotation.
The Coriolis effect is responsible for many of the Earth’s weather patterns and how water drains from a bathtub or toilet.
The effect also plays a role in how aeroplanes travel from east to west and even in the rotation of the Earth itself.
Understanding the Coriolis effect is essential for studying the Earth’s climate and weather, and it is a fascinating topic for anyone interested in science and physics.
