ATL: Ex Tropical Storm EARL - Discussion

[bebert0555]

Buoy data can be very helpfull.

Indeed bouy data can be helpful. Last night it proved that Earl was not much of a storm. I looked at several bouys all of the way out to the canyon and never saw one gust over 70.

Earl may have had high winds aloft, but barely even hurricance force gusts at the surface, if that.

Just reminds us that airplane recon is nice, but does not tell the whole story.

One has to remember that if I am not mistaken winds start at 30' while the bouy is at sealevel but how much of a difference ??One of the members here on the board reminded me while he had to build his house 30' up for surge reasons he put himself into the winds of the storm and then start building for that.

The winds don't start at 30 ft, they're measured at the standard height of 10 meters (33ft). Most of the buoys have their anemometers at about half that height. A hurricane's winds typically increase from ground level (or sea level) to a height of around 1500 ft. But the height of a hurricane's max winds can vary a great deal. Mitch's (1998) max winds when it was a Cat 5 were only a few hundred feet above the ground.

So how mush of a difference does that additional 16' incurr on the anenometer WX57?

Very little over the water. Hardly measurable in most cases. But when the wave heights increase to above 16 ft or more, the anemometer will dip below the tops of the waves around it, possibly shielding it from some of the wind.

Hello Storm2K from Yarmouth, NS! Starting to get foggy and cool here, still almost dead calm though. Put all the lawn furniture and plants in the garage and fired up the generator, but hopefully Earl will weaken enough to not knock out our power. It looks like he'll only be a tropical storm when he passes by us, and that coupled with his speed I don't think there will be much damage done. I'll keep posting as the storm comes nearer if possible.

Thoughts on what/when we'll experience in Cambridge, MA?

For those of you in MA and NS, Earl is a shell of himself now. I know that at my house, 50 miles inland, we did get a little rain this morning, but Earl was far enough of the coast that even the shoreline in NJ didn't get that much. Not that much wind either, but the waves were huge.

They have the center coming within 40 miles of my house, I hope you're right! I'm on the east side.

00Z models initialize as a 60kt tropical storm.

Did not think of the wave aspect when I looked at a couple of bouys it was 17-18' waves ouch!

958mb and a tropical storm - that has to be almost unprecedented.

To understand wind study laminar flow, turbulent flow and boundry layer....MGC

Indeed. Probably from transisting into an extratropical storm. Should be worth studying, like why Wilma had 155 mph winds and central pressure of 892 mb.

Thanks Cainer. Stay safe.

Stay safe cainer. Also, the forward movement will contribute to larger gusts.

Thats the sort of pressure-wind relationship that you'd expect in a decent strength Extratropical system really.
