    You may have heard about a bit of dust in Australia in the last day or so.

    NASA images. In Griffith, we had it a day earlier. I thought it was a bit redder than the image show. You can see how widespread the storm was. There is some talk about 'raised dust' for us tomorrow as well.

    According to an expert on the news last night, this involved several million tons of topsoil!

    Down here in Victoria it is cold and wet, so we missed out this time.
    Regards

    Darwin must be churning in his grave (an oblique reference to his book on worms!)

    There doesn't seem to be much of a problem - you just click on the photo to get rid of all the dust!

    That's the beauty of (some of) the Boston Globe photos.
    Whenever the Aussies get stroppy, you click, and they are buried under dust again!

    I saw the image but where is this dust coming from? At first, I thought it was left over from the fires because of the way the NASA picture looked. Here I'm complaining about Tazzy shedding and you guys are worse off.
    Carpy Diem, it's .

    The dust came from the Lake Eyre Basin, apparently. But it is hard to know. There are always areas of drought and areas of flood and fire in Australia. A simplistic answer, I know. Even though there is water in Lake Eyre at the moment, there are large swathes of land that have not had moisture on them for a long time.

    I said that we were expecting more 'raised dust' and apparently we got it. I ducked down to Melbourne for the weekend and was cold and wet. But now that I am home, the windows show a story that prove that the predictions were true.

    It has been so dry for so long (about 7 years for us) that there is no subsoil moisture anymore. Any wind will whip up the topsoil and strip it and send it on its way to wherever. We get red dust from the north and west and we get white dust from the south and south west. Spring is the worst time and we can get a storm every couple of days.

    Seems very reminiscent of the mid-West dust-bowl in Oklahoma and Texas in the 1930s (different colour dust, though). Thus The Grapes of Wrath...
