Re: Wind Strength

Thanks to typhoon tip, JK and Dougyd for helping me understand the relationship between wind speed and wind force. Sorry I had to leave for a little bit and couldn't reply till now.

In summary:
Wind force is a function of the square of wind speed.
If you multiply by the constant 0.004 you get a mph to psf calculation.
Here are some hurricane related winds speeds and their related wind forces.

ts 39 mph 6.1 psf
cat1 74 mph 21.9 psf
cat2 96 mph 36.9 psf
cat3 111 mph 49.3 psf
cat4 131 mph 68.6 psf
cat5 155 mph 96.1 psf

Thanks again for helping me understand this.
