www.phys.hawaii.eduThe surface of the Earth is an infinite flat plane, or a 2. The surface of the Earth is (nearly) spherical. For a bigger challenge: similarly devise a test for each of the following two scientific hypotheses. (Thought question: How do we even know today, with modern technology, that they are true?) b. The Earth spins. c.
LAPLACE’S EQUATION IN SPHERICAL COORDINATES
www.dslavsk.sites.luc.eduWe can write the Laplacian in spherical coordinates as: ( ) sin 1 (sin ) sin 1 ( ) 1 2 2 2 2 2 2 2 2 θ θ φ θ θ θ ∂ ∂ + ∂ ∂ ∂ ∂ + ∂ ∂ ∂ ∂ ∇ = V r V r r V r r r V (2) where θ is the polar angle measured down from the north pole, and φ is the azimuthal angle, analogous to longitude in earth measuring coordinates. (In ...

In such a situation the relative vorticity is a vector pointing in the radial direction and the component of the planetary vorticity that is important is the component pointing in the radial direction which can be shown to be equal to f = 2Ωsinφ. So, when examining horizontal motion on the Earth’s surface we have
