7 types of rare and amazing clouds (w/ pics and videos)

Mammatus clouds

These pouch-like clouds seem to be the harbringers of thunderstorms and tornadoes and (in many cases) that’s exactly what they are. They form after a long and warm periods and the intensely sheared environment in which Mammatus forms makes them every aviator’s nightmare

Altocumulus Castelanus

These jellyfish clouds are formed a mass of moist air moves fast from the Gulf Stream and gets trapped between two layers of dry air

Arcus clouds

two main categories

a) Roll clouds

b) Shelf clouds

Nacreous clouds

Polar stratospheric clouds (PSCs) and they are formed in the winter polar stratosphere and they have a big impact in creating ozone holes as they further contribute to the depletion of ozone by supporting chemical reactions that produce active chlorine which catalyzes ozone destruction. Bad, bad clouds

Noctilucent clouds

formed at very big altitudes, from 76 to 85 km

Mushroom clouds

result of smoke, condensed water vapor
