Size Gravitational force (i.e. weight) Water surface tension Air pressure Factors affecting the shape:

r r  1 mm Surface tension of a small rain drop pulls it into a sphere.

r 1 mm  r  3 mm A domed top; Flattened bottom; Like a hamburger bun.

r r  4 mm Pressure at the bottom increases when rain drop falls faster; Form a depression at the bottom.

Depression deepens to form an annular ring of water. r  4 mm

Break up. r  1 mm
