Have you ever seen anything quite like this before?
Unusual rainbow-colored clouds brightened up the skies over the Dublin and Belfast areas on February 1, 2016, ahead of Storm Henry’s 80mph winds.
This great display in the heavens, spotted on St. Brigid’s Day morning, was also seen in parts of Britain but are rarely seen quite so far south. The amazing clouds, technically called polar stratospheric clouds or nacreous clouds usually occur at high latitudes, in places like Scandinavia, Iceland, Alaska and Northern Canada.
The clouds, displaying the pastel colors of the rainbow, are formed high in the atmosphere, at heights of up 9 to 15 miles. The colors are created as crystals are formed at temperatures of around -121F. The clouds are normally associated with high winds.
Enter Storm Henry.
