Fractus clouds, also commonly known as "Scud", are clouds which have broken off a larger cloud, usually sheared from the latter by strong winds. Fractus have irregular patterns, appearing much like torn pieces of cotton candy, and can form and dissipate rapidly.[1]
They are named generally for the type of cloud they were sheared from. Therefore, one which was sheared from a cumulus cloud would be called cumulus fractus. Cumulus fractus in particular form on the leading and trailing edges of summer storms in warm and humid conditions. [2] Observing fractus gives indications of wind movements under the parent cloud.
