Effects of Rotation Coriolis Effect
![Page 15: Chapter 8 The Ocean and the Atmosphere. Weather & Climate](https://reader035.vdocuments.net/reader035/viewer/2022062409/56649f4e5503460f94c6f5c0/html5/thumbnails/15.jpg)
Coriolis Effect Coriolis effect is the apparent deflection of
moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere
The deflection is caused by the differential speed of rotation between Earth’s equator and polar regions, relative to an object moving across the Earth’s surface.
