Astronaut Onishi capured this image of Sahara Desert of the African Continent with Soyuz.
According to NASA’s research, Atlantic multi-decadal oscillation of sea surface temperature strongly affects the dryness of the Continent. While heavy rains soak Central Africa each year, the north and the south ends of the continent are fairly dry.
Especially the people living in the Sahel, the southern rim area of the Sahara Desert, are largely influenced by this fluctuation, and dry period between 1968 and 1972 resulted in hundreds of thousands of deaths of starvation.
