It happens periodically in Europe. Several times in my 30+ years in
France I have found my car, if parked outside, covered with grit from
the Sahara.
It should be also pointed out that vast sand or dust movements
have occurred in the history of the earth. The depth of the ice
ages are cold and dry and the dust levels are very high.
They can be seen in the graph

the red plot is dust levels found in the Vostok core samples
at the South Pole.
