Remember the Dust Storm!

About
I've taken plenty of photos from this spot, but this one is a bit different, it was taken at dusk, the day of the first dust storm back in September.
Most of the dust had cleared, but there was still some haze about, and you can see it here.
Enjoy.

- ISO 100, f9, 24-30 seconds each frame, 10mm.

About Dust Storms
A dust storm or sandstorm is a meteorological phenomenon common in arid and semi-arid regions and arises when a gust front passes or when the wind force exceeds the threshold value where loose sand and dust are removed from the dry surface. Particles are transported by saltation and suspension, causing soil erosion from one place and deposition in another. The Sahara and drylands around the Arabian peninsula are the main source of airborne dust, with some contributions from Iran, Pakistan and India into the Arabian Sea, and China's storms deposit dust in the Pacific. It has been argued that recently, poor management of the Earth's drylands, such as neglecting the fallow system, are increasing dust storms from desert margins and changing both the local and global climate, and also impacting local economies.
The term sandstorm is used most often in the context of desert sandstorms, especially in the Sahara, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface. The term dust storm is more likely to be used when finer particles are blown long distances, especially when the dust storm affects urban areas.
The 2009 Australian dust storm swept across Australia on 22–23 September 2009. The capital, Canberra, experienced it on 22 September before it reached the cities of Sydney and Brisbane the following day.
The dust storm was described by the Bureau of Meteorology as a "pretty incredible event" that was "the worst in at least 70 years, if not the history of the state". The storm measured more than 500 kilometres in width and 1,000 kilometres in length and covered dozens of towns and cities in two states. Estimates suggest that during the peak of the storm, the Australian continent was losing 75,000 tonnes of dust per hour off the NSW coast north of Sydney. Comparisons were drawn with a "nuclear winter", Armageddon and the planet Mars.The cloud was visible from space. According to the New South Wales regional director of the Bureau of Meteorology, the cause was an “intense north low-pressure area” which “picked up a lot of dust from the very dry interior of the continent”. The dust storm coincided with other extreme weather conditions which affected the cities of Adelaide and Melbourne.
The phenomenon was reported around the world. The Weather Channel's Richard Whitaker said: "This is unprecedented. We are seeing earth, wind and fire together" It was thought the red dust could travel as far as New Zealand.
