Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission.
When asked to picture the shape of raindrops, many of us will imagine water looking like tears that fall from our eyes, or the stretched out drip from a leaky faucet. This popular misconception is often reinforced in weather imagery associated with predictions and forecasts.
Raindrops are actually shaped like the top of a hamburger bun, round on the top and flat on the bottom. This new video from the Global Precipitation Measurement mission explains why.
