6.A comprehensive observation on macroscop and microscop physics and acidity of a Cb precipitation
7.An extremely dense, vertically developed cumulus with a relatively hazy outline and a glaciated top extending to great heights, usually producing heavy rains, thunderstorms, or hailstorms.
8.When a big rain-cloud becomes electrically charged, and the electric charge lumps between the cloud and the ground, there is a flash which we call lightning.
9.The bright lights of Tucson, Arizona, are more than matched by a flash of lightning far above the city skyline. The sunset scene shows a classic cumulonimbus cloud formation.
10.The scheme has a novel feature that the extraction location of the tracer is not fixed at the center location of the grid, but first optimized at the location where the gradient is maximum in the grid domain, and then by cumulonimbus and uniformity test, the final tracers can be decided.
