22lb Ice Blocks From the Sky 359

cavedwler writes "An article http://www.msnbc.com/news/814100.asp?0dm=-23ET over on MSNBC has an interesting writeup about large ice blocks forming in the upper atmosphere on CLEAR days. Pretty interesting read." The article talks about how this could be a harbinger of massive climactic change. Either way, I'd prefer to not have one of these things smack into my house.

    The article talks about hail, but they fail to
    mention that hail ONLY comes from thunderstorms.
    Just like tornadoes ONLY come from thunderstorms.
    And almost all lighting comes from, you guessed it,
    thunderstorms. They also fail to talk about the
    freezing level. That's how a thunderstorm becomes
    a thunderstorm. A cumulus cloud that's growing
    upwards because of vorticity (air rising fast)
    grows past the freezing level. The top of the
    cloud and the bottom of the cloud get different
    charges and blammo, you have a big floating battery in the
    sky. The hail forms because there are rapidly
    moving columns of air moving up and down
    in the cloud and water trapped in that column
    gets frozen, recoated with water, frozen again,
    etc.

    The ice clouds he's talking about are
    cirrus clouds of some kind. That's basically
    any cloud made up of super tiny ice crystals
    because they are above the freezing level.
    a VERY VERY rare type of cloud is called
    cirrocumulus. This is ice crystal clouds in
    the shape of the puffy white clouds called
    cumulus that sometimes turn into thunderstorms.
    The reason these clouds are so rare is because
    they are unbelievably heavy. It takes an
    incredible amount of 'vorticity' to keep
    them up there, and they don't last long.
    If you ever see very high puffy cottonball
    looking clouds, there's a great chance you'll
    have a thunderstorm soon (24-48 hours) because
    vorticity (air rising fast) is one of the major
    things needed. There is NO WAY upper atmosphere
    vorticity is going to hold water in the air
    long enough for it to weigh 10 friggin pounds.
    There is no way that ice clouds would clump
    together and form ice. There is simply no force
    there to do that work. You might get a ball of
    something more like snow, but definitely not
    ice. I'd be more willing to bet some smartass
    with a catapult is having fun at the ice factory.
    If they said this was related to thunderstorm
    activity, I might buy it. But on a clear day?

      Both cirrus and cirrocumulus are formed from tiny ice crystals (cirrocumulus is when small convective cells form within the cloud). A lot of cirrus is actually of convective origin, the blowoff from thunderstorms.

      Vorticity actually means rotation (turning) of the air, not lifting. However, positive (cyclonic) vorticity near the surface is associated with lifting of the air. That doesn't necessarily mean dramatic convective lifting that produces thunderstorms, but air will be lifted in those regions.

      Hail forms in thunderstorms with strong updrafts. These updrafts are needed to keep the hailstones from simply falling out of the cloud. In order to get giant hailstones, the updraft has to be very strong indeed.

      A 35 pound chunk of ice is on the order of a 10-inch cube (if it's really solid). That's much bigger than any hailstone ever recorded; the biggest known was about 7 inches long and 4-5 inches on the short axis; hailstones are rarely that solid, and it probably didn't weigh more than 5 pounds or thereabouts. I think it fell in Coffeyville, Kansas during a severe thunderstorm (surely a supercell, with a very persistent, rotating updraft, that may well have spawned a tornado). This isn't rocket science; think about what the terminal velocity of a 35 pound chunk of ice is, and the updraft has to be close to that in velocity.

      Any situation where the air is rising that violently is either going to have a very obvious cloud (read: thunderstorm) associated with it; the heat released by the condensation of the water makes the air more buoyant, and hence increases the lift. A dry thermal isn't going to approach that kind of velocity, and even if it did, it would be...well...dry.

      What all of that basically amounts to is...well...that dog don't hunt. The only realistic source of that kind of thing is water being dumped by airplanes at high enough altitudes so that it has time to freeze before reaching the surface. A chunk of ice that big should be easy to save long enough to be examined; they should give a few samples to NOAA, say, and let them inspect it.

        Agreed. I'd like to see some hard evidence of this given our present knowledge of precipitation formation and cloud physics (which admittedly is pretty limited, but certainly precludes events of these kinds).

        The problem I have with the airplane theory, however, is that the instant that the water is ejected from the plane it will break up into thousands upon thousands of tiny drops which will instantly freeze at that altitude. A large mass of water would not freeze instantly due to its large heat capacity, yet at the same time it will not remain together due to the various forces yanking it apart (esp. friction).

        So in other words our "megacryometeor" would (for it to form in the 4-9km AGL range) have to grow from a infinitesimally small nucleus (since allegedly the composition of these things is similar to the composition of rain) to the size of at least a basketball before it strikes the earth. Keep in mind that it can't simply start out as a mass of water the size of a basketball (as mentioned earlier), and thus must grow slowly enough to have all the water freeze/vapor condense onto it without losing it all, and yet somehow stay up in the air without the support of a strong upward current of air to balance out its terminal velocity, which will be on the order of 50 m/s (110mph) by the time it is the size of a baseball, let alone a basketball or more. Note that these upward currents of this magnitude occur *only* in the presence of strong thunderstorms.

        The only thing I can think of that might remotely be able to do something like this is a very strong jet stream placed favorably next to a mountain range. You could then possibly have very strong vertical winds (this is very favorable for cloud formation, however) up to and even exceeding 50 m/s, and under *just* the right conditions you could probably grow a chunk of ice from nothing other than vapor over a long period of time...however we're talking about growth rates on the order of days and even weeks in the absence of clouds for a chunk of ice of any reasonable size. Thus even this highly idealized setup is not realistic, as it would have to persist steady-state for weeks.

        In short, there could be some really weird process out there we haven't the foggiest notion about that is causing this, but I'll believe it when I see it...

          One news report that I saw not too long ago was that an ice block smashed through the roof of a house, and investigators on the scene said it came from an airplane. Indeed, it was the same color of blue as the disinfectant in the airplane toilet flushing water. IIRC, they said that the holding tank had a slow leak, and the water made its way to the exterior of the fuselage (sucked through a hole from a popped rivet, perhaps) where it was broken up into a spray by the air rushing past. The spray collected and instantly froze directly behind the leak on the cold aluminum skin where one of the tail fins joined to the fuselage, collecting and forming a sizeable ball of blue ice. (Heating due to friction would have been negligeable here.) As the plane approached for a landing, slowing down and descending into a warmer layer of air, the aluminum skin conducted just enough heat to cause the blob of ice to separate from the surface and fall, crashing through the roof. Into the bathroom of the house. Imagine the odds.

    for me is not whether or not ice can form. Of course it can form. The question in my mind is what kind of wind can sustain such a large glob?

    Traditional hailstones form in the updrafts of thunderstorms--the more forceful the updraft, the larger the hailstones. This begs the question of what kind of wind is keeping these things aloft and allowing them to form. The answer could be easily found in a wind tunnel. What you need to know is the terminal velocity of these ice "blocks". I assume they are not actually blocks. That would just be too wierd.

    Perhaps, there is some kind of ice structure that forms and has a very low terminal velocity... ice parachutes with thick centers? Then, as it falls through the atmosphere whatever it is that reduces the terminal velocity melts, leaving the "payload".

    Also, is there any correlation between these things and anything else (like contrails?). If there is, then maybe we could use doppler RADAR to look for clear-air updrafts, and a telescope to view these things as they form. Of course, maybe these things are highly localized--little tornados in the upper atmosphere... maybe they are smaller than the resolution of the RADAR.

    At any rate, I just hope these things stay away from my head.

      Radar wouldn't really be able to help you much here. Weather radar's resolution is on the order of tens of meters, and the stuff you're looking at would need to be somewhat reflective to radar.

      The wind that's holding up the block wouldn't be very visible either if it really was in a clear sky. Rain reflects back to the radar, but plain wind isn't very easy to see.
    • Ok, I've read that the terminal velocity of a man falling is somewhere around 120mph. Since I never see the weight of these falling people mentioned, lets say he weighs around... 180 lbs sound good? Maybe 200 for kicks and grins. So lets divide 120 by 200 ... That's approximately .6 mph per pound. It's looking like (if my busted math is correct) that it'd take a sustained updraft of at least 13.2 mph to keep the thing aloft (keeping in mind it doesn't start out at 22 lbs), probably more given the density of a 22 lb block of ice. I'll cheat and say 20-25mph to keep it aloft. if I were just looking at the numbers I'd say it could work, but then you have to figure in crap like stability of the airmass, how long a 20 mph updraft can be sustained while the thing froze, ambient temperature, etc, etc... It seems pretty damn unlikely conditions would stay stable long enough for it to form. But then, I'm far from a meteorologist... I could see the ice parachute thing, but the conditions required to form such a delicate structure... Yeesh...

    Stories about weird stuff falling from the sky have been with us for millennia. Charles Fort (1874-1932) devoted his life to collecting newspaper clippings of rains of fungi, formless masses of protoplasm, hatchets, masks, the ceremonial regalia of savages, and stones--with and without inscriptions. One of his accounts, The Book of the Damned is online here. [resologist.net] (By "the damned," he means data that science refuses to accept).Written in an almost poetic, tart, prose style, it is very readable. He talks of rains of "Butter and beef and blood and a stone with strange inscriptions upon it." Most of his information was obtained from newspaper accounts.

    I'm inclined to take a very skeptical view of any stories about weird stuff falling from the sky. Maybe it's true about the blocks of ice, and maybe Fort's falls of frogs and fishes were true, and maybe other accounts of worms, snails mussels, snakes, turtles, and even a whole calf are true.

    But I'd want to see heavier evidence than an MSNBC story.

    Anyway, Fort would have loved this one.

Has it occurred to anyone that since there is a lot of money for climate change research, scientists, in response to the inevitable reporter question, will of course say it *might* have something to do with climate change.

    It is time for a new fear. Climate change is getting trite!
  • Let's do the math. If the ice falls from 6 mi, and assuming no friction and melting (the perfect physics world), then:

    6 mi * 1600 m/mi = 9600 m
    Kinetic Energy = Potential Energy, so 0.5*m*v^2 = m*g*h, and the m's cancel, and then we solve for v:
    v=sqrt(2*g*h)
    h=9600m, g=approx. 9.5 m/s^2 at that height.

    Therefore, the ice will hit the ground at about 430 m/s, almost the speed of sound!

    "Martinez-Frias said only around a fifth of the ice meteors are ever found."

    Ermm... how do they count what they haven't seen?

    "Martinez-Frias suggests that because global warming involves one level of the atmosphere getting colder while another gets hotter, some ice clouds now remain longer."

    Logic dictates that if global warming causes one level to get colder while another gets warmer, that global cooling would cause one level to get warmer while another gets colder. Am I repeating myself? And besides, this is a suggestion, not a formulated hypothesis based on evidence. At least not yet.

    Scientific fact is that water vapor and carbon dioxide are the most abundant greenhouse gas. As our combustible-fuel appliances become more efficient, there are less hydrocarbon emissions and more H20 and C02 emitted; the net effect on greenhouse gases is the same. Besides, it has been argued that a single volcanic eruption has a far greater effect (neg or pos, you decide) on the atmosphere than the entire history of mankind burning stuff.

    One more thing: there's no such thing az a ZEV (Zero-Emission-Vehicle). Electric is displaced emissions -- unless your power is hydro (and "we all know how bad that is for the fishies"). The manufacture of solar cells and batteries/fuel cells require the use -- and disposal -- of tons of toxic chemicals. Nuke also involves toxic waste (nevermind it's the cleanest and safest form of electricity, it's gotten a bad rap by the actions of irresponsible people).

    To say that man (woman too!!) is causing global warming is a crock. If we all went back to eating wooly mammoth cooked over teradactyl dung, I don't think we'd notice any difference in the rate of global climate change.

    "Glad you came professor, we need to know if it's real ice or just an imposter."
    "This *holds it up to the light* is a block of fake ice."
    "Ohh, but Professor, how can you tell?
    "It has a fake fly in it!"

  • I think that it is a simpler explanation and thus MORE likely that this is just a bunch of kids who are testing a trebuchet.
