Coriolisbaserade

Coriolisbaserade describes systems, models, or phenomena that are based on or influenced by the Coriolis effect, which arises in rotating reference frames. The Coriolis effect causes moving objects to be deflected relative to the rotating frame; in mathematical terms the Coriolis acceleration is a_c = -2 Ω × v, where Ω is the angular velocity of the frame and v is the velocity relative to that frame. On Earth, this effect is responsible for large-scale atmospheric and oceanic circulation patterns, such as the deflection of trade winds and the formation of gyres. It also underpins the geostrophic balance that governs many wind and current patterns.

In engineering and instrumentation, Coriolis-based methods exploit the deflection of moving masses to measure flow rates or rotation. Coriolis mass flow meters sense the twist and vibration of a U-shaped tube through which a fluid flows, enabling direct measurement of mass flow independent of fluid properties. In navigation and inertial sensing, devices such as gyroscopes and ring laser gyroscopes rely on Coriolis forces to detect rotation, forming the core of inertial navigation systems. The concept also appears in laboratory demonstrations and geophysical experiments, including Foucault pendulums and rotating tank experiments that illustrate rotational influences on fluid motion.

The term Coriolisbaserade emphasizes the dependence on a rotating frame rather than a separate force in an inertial frame. While widely applicable, the magnitude of the effect scales with rotation rate and velocity, making it most pronounced in large-scale geophysical contexts or precise instrumentation.
