Coriolis Parameter Formula:
From: | To: |
The Coriolis parameter (f) represents the effect of Earth's rotation on fluid motion. It's crucial in meteorology and oceanography for understanding large-scale atmospheric and oceanic circulation patterns.
The calculator uses the Coriolis parameter equation:
Where:
Explanation: The parameter is maximum at the poles (f = ±2ω) and zero at the equator. It determines the strength of the Coriolis effect at a given latitude.
Details: The Coriolis effect explains the rotation of weather systems (cyclones/anticyclones), ocean currents, and the deflection of moving objects on Earth's surface.
Tips: Enter Earth's angular velocity (default is 7.29×10⁻⁵ rad/s) and latitude in degrees (-90 to 90). Positive values for northern hemisphere, negative for southern.
Q1: Why is the Coriolis effect important?
A: It's fundamental for understanding large-scale atmospheric and oceanic circulation patterns that drive weather and climate.
Q2: Does the Coriolis effect affect small systems?
A: No, its influence is negligible for small-scale phenomena like bathtub drains or short-range projectiles.
Q3: How does the Coriolis parameter vary with latitude?
A: It's zero at the equator and increases towards the poles, changing sign between hemispheres.
Q4: What's the typical value of f at mid-latitudes?
A: About 10⁻⁴ 1/s at 45° latitude, which is often approximated as constant in models.
Q5: Are there applications beyond Earth?
A: Yes, the concept applies to any rotating system, including other planets and stars.
