Storm motion nomogram

[Tim Vasquez]

While analyzing storms on radar I've sometimes had trouble quickly working up accurate estimates of motion. I found errors could crop up if I was juggling numbers in my head while doing ten other things. There wasn't a distance/time/speed diagram that I could find on the Internet so I went ahead and created one today.

Feel free to download and use it if you find it useful. The units of distance and speed are not specified since it works for either nm/kt, sm/mph, or km/kmh.

Should your "speed" axis be labeled "distance" instead?

Yikes, good catch.. fixing it now.

Took me a few minutes to figure out what you were trying to accomplish before I realized that Handy chart - thanks!

LOL Tim...I have a laminated cards I took with me on chases, one of which is this same kind of thing...but a chart rather than a graph. I have one for gas usage, and even a reminder card of what shots I need to get throughout the chase & when to do dialysis (so glad I don't need that card anymore), I only used them once in 2006. But studying the cards did get the info in my head better.
