You probably have seen the pictures of the dust storm in Sydney last week, but NASA has weighed in, with the view from the Modis sensor on the Terra and Aqua satellites. These satellites can produce stunning true colour images of the Earth.
So here they are, and I am uploading the 500 meter resolution, so mouse on the image and you can make your video card whimper!
Here is another shot. The length of the dust cloud is over 3,500 kilometers. The distance from Boston to Los Angeles, or Liverpool to Jerusalem!
My wife and I have actually experienced a dust storm of nearly this intensity.
Norman, Oklahoma was hit by one in the late 1970’s while I was an undergrad in the Meteorology program. My grandmother grew up in the dusty bowl of Oklahoma in the 1930’s, and clearly remembers it. They would put wet sheets over the doors and windows to keep the dust out. They would be dripping with mud in an hour!
