Below the flight approach at Lindbergh Field. This is the best area in San Diego for watching airplanes land. If you wait 20-30 seconds after a plane comes by, you can often hear the wake vortex collapsing. The largest planes land at 18:20 (Hawaiian Air) 21:20 (FedEx) and 04:30! Hence the name!
This is the first cache Ive hidden and I can see you from my apartment window! So wave to the East!
A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid in a free (irrotational) vortex are greatest at the center, and decrease progressively with distance from the center, whereas the speed of a forced (rotational) vortex is zero at the center and increases proportional to the distance from the center. Both types of vortices exhibit a pressure minimum at the center, though the pressure minimum in a free vortex is much lower.
