Here’s a very cool video that shows how the shape of falling raindrops is not the teardrop shape that we drew as kids. Instead, it is closer to the shape of a hamburger bun. This video also shows how the size distribution of raindrops in a storm was originally measured using a pan of flour by none other than William Bentley, the famous photographer of snowflakes. This is now used to help calibrate radar signals and to use them to estimate rainfall (which I talked about in yesterday’s blog). You learn something new every day!
