Hurricanes provide a needed function
|
|
Saw on TWC that hurricanes are like global air conditioners - taking heat from the tropics and drawing it up into the polar regions. True?
If so we wouldn't want to find a way to reduce their intensity so much as a way to try to steer them. That's probably not possible given we're talking about forces on a global scale - right?

I tend to agree with that. Looking at the dynamics of hurricanes, they also expel a lot of heat energy into the upper Troposphere and more northern latitudes. They certainly appear to be a balancing mechanism (climatologically speaking) on a global scale. I feel that it would be unwise to attempt to reduce their intensity. Like the saying, "It's not nice to fool Mother Nature."

Could outer rain bands from Emily effect Florida? It looks as if they could on this.

They are very much so needed. They clean the environment. They bring new life by carrying seeds in its winds and waves. They, by the upwelling from the energy being sucked up, essentially recycle the old water and bring the new, cleaner water from the deeps. Hurricanes should never be attempted to weaken because of the sheer environmental affects it could cause.

Well, there is a surge of moisture spreading from SE to NW over the state as an indirect result of Emily. That will enhance our normal afternoon thunderstorms. As to feeder bands, no.

Very much true, Margie. They play a crucial role in maintaining the Earth in energy balance, keeping the tropics from overheating and the poles from being frigid. They make up about 30% of the total heat transport between the midlatitudes/polar regions & tropics, and as such do provide some benefit (beyond what they take away). There's a post lying around here somewhere that I went into a bit more detail with the other day.

Re: Hurricanes provide a needed function

Being the consensus seems to be attempting to steer or otherwise hinder them whould be insane, how about the feasability of harnessing there energy?Now that whould be an incredable power source,imagine wind turbines that whould withstand 150MPH winds for up to 24 hours and a means of storing the energy. At least enough to have stand by power considering the Grid is always knocked out for up to 2 weeks, i'll bet it'll work better than my Honda Generator and be far less noisey.

In Somalia, there is this mountain pass that focuses a lot of wind energy from the Indian Ocean monsoon (think of it as a giant backwards S, with the bottom part of that feeding directly towards Somalia) into a narrow region. Wind speeds here can easily reach 150-200mph.
Before things turned for the worse down there, many scientists advised the leaders of that nation to place wind turbines there and harness the energy, both for their own needs and to sell. Unfortunately, they did not; it's not why they have been in such dire straits since then, but could have helped prevent them from getting there.
Harnessing a storm's energy has some feasibility behind it, but meshing out the technology and making sure the parts don't break under such conditions both still need to be worked out. Cost is probably a concern initially as well, but if located in the primary hurricane strike zones, could have some cost-benefits in the long run. It's an interesting idea, to say the least...

Re: Hurricanes provide a needed function

, Yes , the construction of the turbines themselfs , that is a question i posed to my foreman, who incidently, had a degree from Cal Tec,, he promptly fired back" well, the C-130's can handle a storm cant thay" my question is: is it the same thing? or being that an airplane is a mobile platform will it be subject to the same conditions as a land based platform?

Different requirements for land vs. air, but if it can handle air flight, I don't see why it wouldn't be able to handle land operations. But, the turbines for these wind generators would have to be much larger than those on a plane -- if you increase the surface area under the force of the wind, you increase the stress on the apparatus. Be an interesting modeling study, nevertheless.
