Excerpt via BBC NEWS | Science & Environment | Why raindrops come in many sizes.

Scientists previously believed that the drops collided with each other as they descended, and that these interactions produced a variety of drop sizes.

But the lead author of this study, Emmanuel Villermaux from Aix-Marseille University, explained that there were always “shortcomings” in this idea.

“The drops are not likely to collide that often,” he told BBC News. Real raindrops are so sparse, he said, that it is likely a drop would “fall on its own and never see its neighbours”.
