New Ice Structure Could Help Seed Clouds, Cause Rain

ScuttleMonkey posted more than 5 years ago | from the no-more-scaring-the-cows dept.

Science 100

ScienceDaily is reporting that a new ice chain structure may provide a better method for seeding clouds and causing rain. "Ice structures are usually built out of simple hexagonal arrangements of water molecules and this hexagonal building block motif is easily observed in the structures of snowflakes. However, during their studies Dr Angelos Michaelides and co-workers from the Fritz Haber Institute, Berlin, and the University of Liverpool have discovered a natural nanoscale ice structure formed of pentagons."

About 20 years ago when I was a freshman an the State University of New York at Albany, I had the good fortune to meet Bernard Vonnegut [wikipedia.org] , Kurt Vonnegut's brother. After talking to him a bit, the light went on in my head and I realized he must have been the inspiration for Kurt's ideas about ice-9!

Bernard Vonnegut was a brilliant atmospheric scientist who invented the process of cloud seeding with silver iodide crystals. Despite his achievements, he was a kind gentleman who was more than happy to take the time to talk to a curious freshman about his work. We had several fascinating conversations and he even gave me reprints of his original journal articles on cloud seeding. I learned a lot from him and was inspired by his example.

I seem to remember there was an Outer Limits episode with a similar plot as well. Some kind of artificial structure that caused water to freeze at 45 degrees and melt somewhere around 80, so the world was immediately plunged into an ice age.

initiallty. However ice would reflect light, cooling the earth...

But at 40F, it'd melt again, allowing the earth to heat up, and freeze again.

The balance would end up with either the earth just plain freezing (most likely) or hovering between 32F and 40F in the areas that previously wouldn't have been frozen.

It wouldn't be a warm ice age.

As I look out at the ugly piles of black, dirt encrusted ice, I have to wonder: If white reflects heat, and black absorbs it, why is it that the big piles of white snow are long since melted away, and the big piles of dirty black snow are still here?

Also, a simple experiment. Get a white piece of paper, and a black piece of paper. Put them outside in the sun, and put an equally-sized ice cube on each. The one on the black paper will melt faster.

Maybe in the case of camperdave's question, it has something to do with what is making the ice black?

Re:Curious (4, Insightful)

frogzilla (1229188) | more than 5 years ago | (#27124013)

As snow melts any crud that is on the surface or embedded in the pile collects and makes the surface darker as the pile gets smaller. The clean snow piles that you observed melting more quickly weren't as large or were less dense than the dirty snow piles. I suspect that you probably didn't perform careful observations (as no reasonable, casual observer would) and that if you did you'd soon see that it all makes sense. Also I think you'd find it very difficult to find a clean snow pile in an urban environment. Maybe behind an arena? Even then airborne matter would accumulate on the surface. This happens just about anywhere that snow sits for a long time.

Re:Curious (3, Interesting)

ByOhTek (1181381) | more than 5 years ago | (#27125363)

because it isn't snow, it's ice (well, snow is ice, but ice with a lot of air in it.

First off, that black ice? it's shiny. You flash light on it, it reflects it back, it doesn't scatter it. At the right angle, it's bright because you see the shine, but at off angles, you don't get the scatter - so it's still reflecting more light (reducing heat input), though probably not as much as snow.

Which comes to why it is still around. If you freeze a pool of water (or a trickle of water), it become ice, not snow, because it didn't have a high air content while freezing. Snow is created in the atmosphere where there is much more non-water-vapor than water-vapor in the air.

Most of that ice is re-frozen snow (it melts, and sinks, as it sinks, it gets to cooler areas and re-freezes, maybe the sun goes down, and heat input goes down, so it the stuff that was exposed and warming refreezes as well.

Nowhere do I see a claim that this pentagonal structure is superior, just that this opens up the potential that there are other structures as well and that one yet undiscovered structure could be beneficial for cloud seeding.

This "oddly" seems to have happened only after when I also caught one of your own here @ slashdot, "The End of Days" -> http://slashdot.org/comments.pl?sid=1147437&cid=27056793 [slashdot.org] admitting to using multiple registered accounts to "mod himself up" here and to use those same registered accounts to mod down others (ontop of his use of ac submissions as well to also make it appear he has further supporters).

Man, to the "The End of Days": I would be a bit worried now were I you, because now it's out of my hands @ this point, & you're the only person who might have any reason to do so. Now, I will just go to the hosting provider involved for that website to take care of it, & if I get resistance of any kind, I will prosecute you to the fullest extent of the law.

Next, it's law enforcement who will be contacted, for both libel & criminal impersonation (or whatever charges it carries - you only brought this on yourself).

The rest of you registered accounts users only have "the poster child for an online loser" in The End of Days to blame for this being something any ac can accuse you of, and very possibly be correct in because of The End of Days 'fine example' thereof, because I'm sure that "The End of Days" isn't the only loser here doing it but has exemplified that many of YOU 'registered users' here, quite probably do also, yourselves.

That's what I came here to say. All this means is when searching for new artificial ice nuclei (silver iodide being the most popular right now due to its hexagonal crystal structure) they can expand into new crystal structure candidates rather than just hexagonal.

It does not mean they will find something which is effective as AgI, it simply gives cloud physicists another class of crystal structures to explore.

No the real problem with global warming is the change in climate.

If the conservative wackos are correct and mankind isn't changing the climate on a global scale, then we are truly at nature's mercy unless we want to invent global climate control. Luckily, the anthropogenic climate change skeptics are either ill-informed or corporate-funded or both.

Ungrounded Lightning (62228) | more than 5 years ago | (#27128539)

Do we know that creating rain somewhere will not cause drought elsewhere?

I have heard that it was fear of lawsuits from people downwind, over moisture removed from the air by cloud seeding to create rain on land upwind that otherwise would have ended up as rain on THEIR land, which ended the experiments with cloud seeding to aid agriculture in the USA.

Pentagons?! (1)

DontBlameCanada (1325547) | more than 5 years ago | (#27123397)

As in the symbol often associated with Witchcraft and Devil worship?!

I've often said, "Go to H***!" to people who bother me. Perhaps I should say, "Go to Heaven!" instead?

pentagon != pentagram

Re:Pentagons?! (1)

Camann (1486759) | more than 5 years ago | (#27123667)

actually that's still wrong, it's the combination of the star and pentagon shapes that has the religious meanings. I don't know what the name of that is off the top of my head. Thought it was pentagram but that's just the star shape according to wikipedia...

Re:Pentagons?! (1)

princessproton (1362559) | more than 5 years ago | (#27126143)

I believe the common symbol you are referring to is the pentacle [wikipedia.org] , which is actually a circle and the star, but there is also the symbol used by the Order of the Eastern Star [wikipedia.org] which incorporates the pentagon shape.

Re:Pentagons?! (1)

tabrnaker (741668) | more than 5 years ago | (#27129883)

Right and wrong. You might be thinking of pentagrams which are used in the occult across the world.

If you were thinking of only the United States, then yes, you are correct. The pentagon is not only the symbol most associated with witchcraft and devil worship, but also where most of it takes place.

Science Daily...reporting? (4, Informative)

TimmyDee (713324) | more than 5 years ago | (#27123491)

I think to say that Science Daily does any reporting is stretching the definition of reporting a bit much. I think "rewritten from a press release" is more like it.

If you want a real news piece, with real reporting, check out the article on the same paper over at New Scientist [newscientist.com] . They actually talked with the scientist involved in the study (and one that wasn't).

bush seeded Katrina to raise oil prices after he and his co pilot were already comfortably established in Iraq because bush had the Taliban take down the twin towers and the high gas prices would also strangulate many small businesses thereby causing an influx in military enlistment to further his war on fuel. I know flamebait... but just imagine it kinda makes sense doesn't it?

If ice is falling from the sky, and it melts into droplets and falls as water - what would you call it other than rain?

Anonymous Coward | more than 5 years ago | (#27126585)

water first has to evaporate into the sky. You can't make it rain more if you haven't made more water evaporate into the sky in the first place. Sounds like a better solution would be to just heat up the planet and cause more evaporation. I'm gonna go buy an SUV now.

Frosted windows? (1)

Ungrounded Lightning (62228) | more than 5 years ago | (#27127621)

This relates to a one-dimensional crystal forming on a flat surface.

I wonder if it's related to the early stages of frost formation on windows, where needles of ice form rapidly on the surface before the ice fills in between them?

So how long is it going to be before lots of overpaid lawyers sue the cloud-seeders on the grounds that the communities downwind "own" the rain? Think that's crazy? Try telling that to the communities fighting for the right to put wells in local aquifers against the people way way WAY downstream who think all of the water upstream is theirs.

Ditto. Imagine if Mulholland tried to pull off his water projects today. L.A. would either be a desert or they'd have major desalination plants.

So how long is it going to be before lots of overpaid lawyers sue the cloud-seeders on the grounds that the communities downwind "own" the rain?

I heard (I think it was in a meteorology class back in the '60s) that the early plans for cloud seeding as an agricultural tool had been scrapped for exactly this reason: Concern that the downwind farmers would sue those upwind who used cloud seeding for denying them the moisture that otherwise might have ended up as rain on THEIR fields.

Water rights are a BIG DEAL for farmers. Cloud seeding doesn't put any more water into the air. When it works at all (the conditions must be right) it just makes the water fall out sooner/faster than it would have on its own. So the downwind farmers would have a valid point about the upwind operation "stealing their water".

If the ice crystals are pentagonal, they will form pentagonal snowflakes. This will give us a better chance of finding the snowflake with magic properties depicted on page 00062 of the Principia Discordia.
