Question

1 Centrifugal and Coriolis Force (a) Pretend you are doing science outreach at a middle school and you need to explain why extratropical cyclones (using a different word) spin counterclockwise in the Northern Hemi- sphere. Record a video of your explanation without using the word, \"Coriolis.\" I encourage you use hands-on materials, such as a globe/ball, spinning chairs, weather data visualiza- tions, etc. Make it fun! (b) The Coriolis parameter vector is given by $\vec{f} = (0, 0, 2\Omega \sin\phi) \approx 2\vec{\Omega}$. Explain the validity of the approximations made within the context of the three-dimensional momentum equations. (c) Quantitatively compare the Coriolis and centrifugal forces in the three-dimensional momen- tum equations. Why do we care more about the Coriolis than the centrifugal force?
