More of your amazing pictures of Nacreous Clouds!

We've been inundated with photographs of strange goings on in the skies above The Midlands. What we're seeing is an atmospheric phenomenon rarely glimpsed in England called Nacreous clouds.

These clouds form in the stratosphere between 49,000 to 82,000 feet during polar winters, when the temperature drops below -78 degrees Celsius. Nacreous clouds form in the lower stratosphere over polar regions when the sun is just below the horizon. The clouds are illuminated from below and often glow in vivid colours and will often remain visible for a couple of hours after sunset and through the night as they are lit by moonlight.

Usually it is far too dry at this height for clouds to form, but during the polar winter the temperature can drop low enough to promote the clouds’ development.

They are most likely to be viewed during twilight when the sun is between 1º and 6º below the horizon and are most likely to be seen at higher latitudes such as Scandinavia and northern Canada.

Sometimes known as mother of pearl clouds or rainbow clouds for their distinct appearance, nacreous clouds are laced with vivid iridescent light from below the horizon.

We’re so used to stories about unusual weather phenomena being bad news, we’ve almost forgotten how it can sometimes put on a spectacular show for our enjoyment. Enjoy viewing the photographs and if you'd like to share yours email us at centralweather@itv.com
