Dang
September 7th, 2007
We slept right through it, but that must have been one heck of a typhoon. I had tied down the cover on the exercise machines, and I mean tight. Polyethylene twine, tied off in multiple knots, up and down the machine in four or five different places. I did not imagine that it was possible for it to come off; the wind itself tended to flatten the cover against the side of the machine.
But when we woke up just now, the cover was completely off, hanging on to the machines by just a string.
I hope those things don’t rust….
If the wind hits the wall and then flows up and down, and then the down air hits the balcony floor and heads outward, it might also go upward around an object on the balcony, which would push a tarp off if it had been applied from the top of the object. If the tarp is applied from the side facing the wind, and then goes under the object and above it, and ties along the side not facing the wind, it might fare better. One could see the air flow pattern with a 1″ x 10″ piece of cloth, held at one end, and moved around the porch. The incoming air needs to go somewhere after it hits the wall, and that is when one can get some swirling. I’m not sure how it is swirling. The cloth could help with that.
