In general on what objects is the Coriolis effect detectable?

The Coriolis effect is detectable on large-scale objects and phenomena, particularly those that involve significant distances and durations, such as the movement of air masses (weather systems), ocean currents, and large-scale projectiles like missiles. It is most prominent in the atmosphere and oceans due to the Earth's rotation, influencing wind patterns and oceanic circulation. The effect is negligible for smaller objects or short distances, where other forces dominate.
