- Rare ice crystal cloud form: lumps of Cirrus drop delicate fallstreaks
- W003441Z
- Rare ice crystal cloud form. Lumps of Cirrus cloud drop delicate fallstreaks that curve to the right as changing wind velocities reshape the falling ice crystals. Each cloud element looks like a single entity but is, in fact, made up of many small elements merged together. Continuous sublimation occurs only at the top until crystals grow larger and fall out. See them expand in W003458Z.
