2 Coriolis Effect The Coriolis Effect is an apparent deflection of moving objects caused by the rotation of the Earth. From Earth's perspective, an air mass or water current moving over the revolving Earth appears to deviate from its straight path. This deviation is right in the North and left in the South (Ak et al., 2020). Causes of the Coriolis Effect: The Earth's rotation causes the Coriolis Effect, which deflects moving objects. An air mass or water current moving across the revolving Earth appears to veer from a straight course. This deviation is right in the North and left in the South. The Earth's rotation creates the Coriolis Effect, an optical illusion that affects object trajectory (Zhou et al., 2023). Factors Affecting the Coriolis Effect: Latitude: Latitude affects the Coriolis Effect, crucial to understanding Earth's rotation dynamics. Earth's slightly flattened poles and bulging equator make it most noticeable at the poles and least noticeable at the equator. The poles rotate slowly, while the equator rotates fastest. Rotational speed affects Coriolis Effect deflection. With low rotational speed, the Coriolis Effect is highest toward the poles, veering moving objects. The Coriolis Effect is weaker in the equator, with maximum rotational speed, resulting in less deflection. Motion Speed: Moving object speed determines Coriolis Effect strength. Faster objects deflect more due to the Coriolis force. Two objects with identical initial velocities but differing speeds demonstrate this relationship. Faster objects with higher kinetic energy have a stronger Coriolis

3 force, deviating more from their original trajectory (Nouri et al., 2020). The Coriolis Effect shapes air and ocean currents in variable-speed atmospheric and oceanic circulation. Motion Direction: The hemispheres deflect differently due to the Coriolis Effect, which acts perpendicular to motion. Deflection is right in the Northern Hemisphere and left in the Southern. Earth's rotation conserves angular momentum. As a traveling object crosses latitudes, its velocity remains constant, but Earth's rotational motion deflects it. Globally, this perpendicular deflection pattern affects air circulation, ocean currents, and other dynamic systems. Atmospheric/Oceanic Results of the Coriolis Effect: Wind patterns: The Coriolis Effect creates westerlies, trade winds, and polar easterlies worldwide. Trade winds blow toward the equator because the Coriolis Effect is less there. Westerlies form when air masses move poleward, and the Coriolis Effect deflects them westward. Polar easterlies form as air travels from the poles to lower latitudes and deflects eastward. Global heat and moisture distribution depend on these wind patterns, affecting regional climates and weather. Ocean currents: Ocean currents are shaped by the Coriolis Effect. Ocean currents flow counterclockwise in the Southern Hemisphere and clockwise in the Northern. The Coriolis Effect on moving water masses causes this direction. Surface winds generate ocean currents, while the Coriolis Effect deflects them, forming circulation patterns (Dagan et al., 2021). The Gulf Stream and Antarctic Circumpolar Current demonstrate this. The Coriolis Effect affects ocean currents, affecting local and global ecosystems by transporting heat, nutrients, and marine life. Cyclones and hurricanes

4 The Coriolis Effect helps tropical cyclones like hurricanes originate and intensify. The Coriolis Effect provides spin and shape to these storms. A tropical storm must be far from the equator to use the Coriolis Effect. Warm ocean waters evaporate, creating low pressure. The Coriolis Effect spins the system into a cyclonic shape. The Coriolis Effect shapes the storm's direction and rotational dynamics as it increases. Understanding the Coriolis Effect helps predict and manage the effects of tropical cyclones on coastal areas globally.
