These strange clouds were pho­tographed in Queens­land, which is the only place in the world where they form reg­u­larly.

Known as Morn­ing Glory clouds, the phe­nom­e­non can be ob­served in the morn­ings of days with high rel­a­tive hu­mid­ity and force­ful on­shore wind.

The clouds con­sist of con­densed air that rises rapidly on the front of the cloud and de­scends slowly at its cen­tre and on the rear side.

The phe­nom­e­non oc­curs, when air with dif­fer­ent char­ac­ter­is­tics meets, pro­duc­ing a rolling bound­ary. The cloud is pro­duced at the top of the lower air mass.
