I totally get that. TV images cannot portray the depth or extent of destruction.

I believe, that's a true story (about hiding the gaming tables). I still have a couple of casino chips that came from the Balinese Room and I know someone who worked there. For those not as familiar with Texas, when he says Texas Rangers, he's not talking about a baseball team.

This gives an idea of what different winds can do. Chilling.

Whoah! And there isn't anything left to destroy after they get to 156 mph, and they are predicting 200 mph, with higher gusts?

Here's a live web cam at La Manzanilla. I've been watching the storm surge come in.

Yeah the wind has really picked up in the last few minutes- the trees are being whipped around. It would be cool if there was live sound too. Glad I'm not there.
Ack, the camera was just blown over. It's pointing downward now. See the water is almost to it.
<edit> someone just fixed the camera. Thanks!

It is back up. Must have been the guy who walked in front of it a few minutes ago.
EDited: Now it is off for good (one hopes).

Our family compound in Cabo got hit last year by ODILE. It was a monster storm. This one is quite a bit bigger. Scary stuff.

I was in Cabo two weeks ago. I found the locals to be incredibly kind and gracious. My heart is breaking for the people in PV. Many of their homes could probably not withstand a CAT 1 hurricane. And, like someone else said they didn't get much advanced warning.

I don't think Austin will see Patricia this weekend. But they are already dealing with another, unrelated deluge.
According to the tracks, they don't show anything after Saturday afternoon still in Mexico, indicating that it will be considered dissipated by then. Which is fine by me as early projected paths had it sweeping through south Texas.

It was only a tropical storm before Wednesday night - so "Surprise!!!"
Made landfall at 165mph !!!!

IIRC my physics, the force against a surface of a 200 mph wind is NOT twice as strong as a 100 mph wind, it is 3 times. The force cubes vs doubles.

I think you are correct that the force of the wind is cubed with velocity. But a doubling cubed is 8x, not 3x. Yes, a 200 mph wind has eight times the force of a 100 mph wind.
Unless both of our physics memory is wrong (mine sure could be). But I'm certain it is at least a square function, which would be four time the force.
Hah - it's more complex than that (no wonder my memory is foggy):
from wiki (Drag):
Quote:
Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow.
...
For high velocities (or more precisely, at high Reynolds number) drag will vary as the square of velocity. Thus, the resultant power needed to overcome this drag will vary as the cube of velocity.
|
So I guess they add the linear force, and the squared force? I didn't go deep enough to determine if >100 mph air speed is considered 'high velocity', but considering speed of sound is ~ 700 mph, I would think 100 is 'high'.

It appears that the storm did limited damage because the 200 mph area around the eye was restricted to a small swath. Also its path took in the mountainous region south of PV where it quickly lost the power picked up from the 30 degree ocean waters.
No serious damage to PV. Mainly just travel disruption for the air travelers.

Kcowan, thanks for your post. It is great to hear that PV, and you, are OK.

Wind speed has to be very slow for a laminar flow. Even the slightest breeze already causes turbulence behind an object. So, for all practical purposes the drag force is always considered to vary as the square of speed.
Aerodynamicists always use D = 1/2 rho A Cd V^2. I myself have not encountered an application where they work in the linear region (I am not an aerodynamicist), but guess that must be very special.

Interesting info but personally, I don't need pencil and paper, a calculator or mathematical formulas to know that 200+mph winds hitting most residential structures built today = a lot of destruction

Well, it didn't take long for Patricia to get her own Wikipedia entry!
https://en.m.wikipedia.org/wiki/Hurricane_Patricia
Thank goodness the immediate effects have been far less severe than anticipated. Of course there will be a risk of mudslides and flooding.
