The formula calculates the latitude of a position on Earth's surface based on the horizontal component of Coriolis acceleration, angular speed of the Earth, and current velocity. It's derived from the Coriolis effect, which describes the apparent deflection of moving objects due to Earth's rotation.
The calculator uses the formula:
Where:
Explanation: The formula calculates the inverse sine of the ratio between Coriolis acceleration and twice the product of Earth's angular speed and current velocity.
Details: Accurate latitude calculation is crucial for navigation, oceanography, meteorology, and understanding Earth's rotational effects on moving objects and fluid dynamics.
Tips: Enter horizontal component of Coriolis acceleration in m/s², angular speed of Earth in rad/s (default: 7.2921159×10⁻⁵ rad/s), and current velocity in m/s. All values must be positive.
Q1: What is Coriolis acceleration?
A: Coriolis acceleration is the apparent acceleration experienced by objects moving in a rotating reference frame, such as Earth.
Q2: Why is angular speed of Earth important?
A: Earth's angular speed determines the strength of the Coriolis effect, which varies with latitude and affects large-scale motions in atmosphere and oceans.
Q3: What are typical values for current velocity?
A: Ocean currents typically range from 0.01-2 m/s, while atmospheric currents can reach 10-50 m/s.
Q4: Are there limitations to this formula?
A: The formula assumes simplified conditions and may not account for all real-world complexities in fluid dynamics and Earth's geoid shape.
Q5: How accurate is this calculation?
A: Accuracy depends on precise input values. For navigation purposes, additional corrections and more complex models are typically used.
