Snow Fell In The Sahara For The First Time In 37 Years
In the immortal words of Band Aid (however you feel about the song): There wont be snow in Africa this Christmas time. Well, thats not strictly true.
On December 19, snow fell on the edge of the Sahara desert, giving the red sandy dunes a pretty smattering of the white stuff for the first time in 37 years.
The world was alerted to this event by amateur photographer Karim Bouchetata, who posted his photos onFacebook,showing the snow covering the sands surrounding the Algerian town of Ain Sefra. Ain Sefra is located between the Atlas Mountains and the northern edge of the Sahara, around 1,000 meters (3,300 feet) above sea level, and is known as the gateway to the desert.
Everyone was stunned to see snow falling in the desert; it is such a rare occurrence, Mr Bouchetata said. It looked amazing as the snow settled on the sand and made a great set of photos. The snow stayed for about a day and has now melted away.
Of course, Africa does in fact have snow. Kilimanjaro in Tanzania is famously topped by a snowy cap, while in the Atlas Mountains just 72 kilometers (45 miles) from Marrakech, Oukaimeden has the unlikely honor of being Africas highest ski resort at 3,200 meters (10,500 feet).
But seeing as the last recorded snow in the Sahara was 1979, its still exciting.
In fact, NASAs Earth Observatory has released a natural-color photo of the snow in the desert from space. Taken by the Enhanced Thematic Mapper Plus on the Landsat 7 satellite, the image shows the snow on the ground near the Morocco/Algeria border, southwest of Ain Sefra.
NASA has also revealed satellite images of the Saharan Atlas range in December for the last four years, taken by their Aqua and Terra satellites, to demonstrate how unusual this event is.
The false-colour images are rendered in infrared, shortwave infrared, and visible red wavelengths, with the snow showing as a bright blue-green.
So if you’re dreaming of a white Christmas this year, however unlikely, you might still get your wish.
