Also known as wave clouds or wind row clouds they generally run parallel but can also appear to interweave with one another.
Formed by rising air, these clouds are hard to see unless illuminated in just the right amount of sunlight. Coincidentally this lighting typically forms a halo.
In Latin there name means “curly hooks”. They are generally very sparse in the sky and extremely thin.
With its characteristic flat, anvil shaped top this cloud can easily form into supercells and generate severe weather patterns such as tornadoes.
Punch Hole Cloud
Also known as fallstreak hole, these anomolies are formed when the water temperature in the clouds is below freezing but the water hasn’t frozen yet. Quite often they are associated with UFO sightings.
It may seem impossible but in fact several artists have used various techniques of creating the ideal conditions for indoor clouds to form as part of their artwork.

These stationary, lens shaped clouds usually form when moist air flows over the side of a mountain range.
Although typically associated with nuclear weapons, any large blast is likely to produce a mushroom cloud including volcanic explosions and meteorite impacts.
Also known as jellyfish clouds due to their interesting appearance, these form when moist air gets trapped between two layers of dry air.
Possibly the least understood cloud formation in the atmosphere these clouds are also the highest. Residing at an altitude of over 80 km they literally sit on the verge of space and are usually only seen closer to the poles. To see them, however, conditions have to be just right, with the sun below the horizon providing the right angle of illumination.
