Australia is home to one of the world’s rarest meteorological phenomena, which most people have never heard of. Known as morning glory clouds, these long bands of cigar-shaped formations can stretch up to 1,000 kilometers (621 miles) in length. Are these natural formations?

These admittedly are intriguingly like man-made objects but in fact are natural formations, a product of unusual wind turbulence that has a kind of regularity and causes cloud formation according to the swirls of airflow, and these persist. So it is created by temperature differentials and wind movement, and the differentials serve to keep the clouds relatively stable in place for long periods of time, relatively speaking. There is nothing unusual other than the miracle of nature at work here.
