And while breathing is hard and transportation has ground to a standstill, the photos are spectacular. Dust storms are common in Australia's central desert, the "Red Center," but rarely are they blown eastward toward the coastal cities. To put the density in perspective, air pollution levels have been measured at 15,500 micrograms of particulate matter per cubic meter of atmosphere.
