Detailed Description

Why are raindrops different sizes?

When the drops finally reach the ground, the biggest drops will be the ones that bumped into and coalesced with the most droplets. The smaller drops are the ones that didn't run into as many droplets. Raindrops are different sizes for two primary reasons.

  1. initial differences in particle (condensation nuclei) size
  2. different rates of coalescence.
