The Sahara is the largest hot desert in the world. Winter is the season when any rainfall might fall in this area. But on Tuesday January 19 snow fell in the Sahara desert. It was the third time in human memory that snow has been seen in the Sahara.
On Tuesday (Jan. 19), one of the world’s driest places awoke to an otherworldly dusting of frost. The Desert is an extremely hot region. An area about 3,600,000 square miles (9,200,000 square kilometers), the desert is about the size of the United States and stretches across much of North Africa. Entirely northern Africa is called Sahara desert. Total 11 countries form the Sahara desert.
Winter is the season when any rainfall might fall in this area. The air above the desert is so dry, that often rain doesn’t reach the ground or arrives in very small quantities. There have been three recorded episodes of significant snowfall. The first was recorded in 1979, the second in December of 2016, and the third most recently on January 7, 2018.
Reports in the media indicate that snow has also fallen in Lebanon, Syria and Iran – where some regions have been buried under a layer of snow.
The Sahara is the largest hot desert in the world and the third largest desert overall, smaller only than the deserts of Antarctica and the Arctic. For several hundred thousand years, the Sahara has alternated between desert and savanna grassland in a 20,000 year cycle.
