Also, an FYI. I listened to your interview with Ross and Carrie. You are mistaken about the term “round” and conflating it with the common confusion between “circular” and “spherical”. Circles are round, but so are spheres and even cylinders.
I would also like to know more about it from Mark. I have heard that there are many documented cases of the cyclonic storms and drain vortices that are opposite to the expectation. Can you explain how that is possible with the globe model first? Thanks
To be clear, the Coriolus effect is not relevant to toilets, bathtubs or drains of any kind. As regards the effect as it occurs due to the rotation of the Earth, the effect is only significant over large distances. The vortices we see in drains are a result of angular momentum.
