*Wind, Fallout, and Toxic Gasses*
How fast is it coming my way?
Or how long do I have until it gets to me or my family?
I worry about Nuclear/Dirty bombs and or attacks/ industrial accidents and how long it will take the fallout or poison gas to get to my home or office.
Note: A nuke would involve high altitude, wind, speed and direction but the same mathematical formula would apply.
Let’s talk about surface winds and directions for a moment.
The wind direction is reported with a meteorological angle:
0° - from the north (northerly)
90° - from the east (easterly)
180° - from the south (southerly)
270° - from the west (westerly)
It is also important to note that a wind report will say winds West 3 M.P.H. That means it is coming from the west (I.E. blowing from the west to the south. ).
Let say we have a 3 M.P.H. wind from the west and I live 2 miles form the source of contamination. Let’s say it’s a chlorine spill from the railroad.
A mile is 5280 feet
1 hour is 60 minutes
So a 1 M.P.H. wind is 88 feet per minute.
88 times 3 = 264 feet
A 3 M.P.H. wind means a toxic gas can travel 264 feet in 1 minute!
Now recall I said I live 2 miles from the spill that’s 10560 feet divided by the wind speed of 364 feet per minute.
10560 divided by 364 = 29.010989 so let’s just say 29 minutes.
Here is the wind speed up to 20 M.P.H.
1 = 88 Feet
2 = 176 Feet
3 = 264 Feet
4 = 352 Feet
5 = 440 Feet
6 = 528 Feet
7 = 616 Feet
8 = 704 Feet
9 = 792 Feet
10 = 880 Feet
11 = 968 Feet
12 = 1056 Feet
13 = 1144 Feet
14 = 1232 Feet
15 = 1320 Feet
16 = 1408 Feet
17 = 1496 Feet
18 = 1584 Feet
19 = 1672 Feet
20 = 1760 Feet
