Like wheels on a bike These flakes look alike. Each type has quite similar traits. Create varying forces That cause complex mixed crystals to form. So while some flakes can all look the same, Most are not nearly so tame. As the Nature from whence each one came.
Big drops fall from moist warmer air, Or when smaller drops join, way up there.
Hailstones will grow When strong updrafts blow. A thunderstorm has those to spare. Is freezing rain. Traffic it slows. Each type of cold precipitation Has its own origination.
