Updating my dust devil spreadsheet.Feel free to add to it. Keep it in mind when you see a dust devil. You don't need all that wind and stuff. It's goot to estimate height and width though. Gosh i really need an anemometer. I'm adding all the ones i saw in May 2010 that accompanied Phi, and got me all the way up there in the Greek alphabet.
Why did you only say that it's updated today?
