My only concern with the BoM calendar was the image for March - actually - the caption for the image for March.
The caption states "A storm front crosses Cable Beach, Broome, north-west Western Australia, 16 March 2008, 4pm".
The image is actually showing the anvil of a storm spreading out about 15km (est.) above the surface....hardly a "storm front" crossing Cable Beach. The only impact it would have on Cable Beach is that it casts a large shadow.
