Mid-Holocene extreme precipitation in the Tibesti, Central Sahara
This study found that during the mid-Holocene, precipitation from the Mediterranean Sea, driven by northerly winds, filled crater lakes in the Tibesti mountains, even though it's in the Sahara Desert. The Trou au Natron lake was much larger than the Era Kohor lake due to the mountains enhancing rainfall in the north, and winds blowing moisture away from the south.
