Strange 'rapture' cloud appears over Australia
Quote:
On Monday, over the sea-side town of Wonthaggi, Australia, southeast of Melbourne, a bizarre phenomenon formed in the clouds, prompting many residents of the area to take to social media for answers.
Spotted early in the afternoon on Nov. 3, 2014, this strange, iridescent shape in the clouds made it seem like something supernatural was going on.
It's certainly pretty bizarre, and definitely something you don't see every day. However, it's entirely natural. No alien or divine intervention required, and it's not harmful in the least.
It's a fallstreak hole, so-called because the water in that region of the cloud is falling to earth, producing those pronounced streaks it does, and leaving behind a hole in the cloud.
How does this happen?
If you've ever taken a close look at weather reports, there's always something included called the dewpoint temperature. This is the temperature the air needs to reach before the water vapour in the air will condense out, to form clouds, fog or dew (or all three!). However, a key 'ingredient' to this condensation is that the water vapour needs something to condense onto - dust, pollen, particulate matter, etc - which are known as cloud condensation nuclei.
So, when a cloud forms, each of the millions to billions of tiny water droplets contained within surrounds a grain of dust or pollen or particulate matter.
