NOAA GOES-10 visible imagery (above, left) reveals a train of gravity waves propagating westward across the Pacific Ocean between Baja California and Isla Guadalupe, Mexico on 30 September, 2001. The gravity waves were apparently generated by outflow from convection within a rotating outer band of Tropical Depression Juliette. Subtle von Karman vortices are also evident in the animation, moving southeastward in the lee of Isla Guadalupe.<
