Explanation
No. Falling raindrops do not normally have the pointed teardrop shape used in drawings. Small drops are approximately spherical, while larger ones become flatter.
NASA explains that air resistance changes a drop's shape as it grows and falls. USGS describes the competing effects of surface tension, which favours a rounded shape, and air pressure, which deforms larger drops.
There is no single shape for every raindrop. Size matters, and sufficiently distorted drops can break apart. The familiar pointed symbol should not be mistaken for the shape of rain falling freely through the air.
Key takeaway
Small raindrops are rounded; larger ones flatten. A pointed teardrop is a visual symbol, not an accurate model of falling rain.
