Cirrus castellanus or Cirrus castellatus[1] is a species of cirrus cloud. Its name comes from the word castellanus, which means of a fort, of a castle in Latin.[2] Like all cirrus, this species occurs at high altitudes. It appears as separate turrets rising from a lower-level cloud base. Often these cloud turrets form in lines, and they can be taller than they are wide.[3] This cloud species is usually dense in formation.[4], it indicates atmospheric instability
