Sandstorms Whip Across China‎

1954-1991: The multi-year droughts in portions of North America of 1954-56, 1976–78, and 1987-91 were noted for dust storms of the intensity seen in the middle 1930s over some fraction of their coverage and timespan, and more sporadically during the times between. The three multi-year droughts were similar to the 1930s in storms being raised by synoptic scale weather events such as cyclones and cold fronts; otherwise the most common trigger is the outflow from convective activity, known as a haboob. Significant events of the latter variety occurred in Colorado and Kansas in May 2004 with winds to 100 mph, Minnesota and Wisconsin in June 2004 causing significant damage, and the upper Middle West in May 1988, notable for strong electrification and lightning activity and by one estimate reaching 30 000 ft or more. The first and third of this list reached black blizzard intensity, causing total blackout for some period ranging from 90 sec to 10 or more minutes, over some fraction of the ground covered. The 1987-91 drought was especially notable as in the 1930s for the large number of rain of mud events, often generated by dust in suspension and/or carried on upper-level winds.
1971: A dust storm that occurred near Tucson, Arizona on July 16 was extensively documented by meteorologists.
1983: 1983 Melbourne dust storm: On the afternoon of February 8 a huge dust storm originating in the Mallee region of Victoria, Australia covered the city of Melbourne.
1997: On May 2, a sandstorm in Libya and Egypt killed 12 people.
