China to Use Silver Iodide & Dry Ice to Control the Weather

eldavojohn writes "While we made light of it before, the MIT Review is taking a serious look at China's plans to prevent rain over their open 91,000 seat arena for The Olympics. From the article: 'China's national weather-engineering program is also the world's largest, with approximately 1,500 weather modification professionals directing 30 aircraft and their crews, as well as 37,000 part-time workers — mostly peasant farmers — who are on call to blast away at clouds with 7,113 anti-aircraft guns and 4,991 rocket launchers.' They plan on demonstrating their ability to control the weather to the rest of the world, and expanding on their abilities in the future."

    The main areas in which evictions have been carried out within the Municipality of Beijing during the period between 2000 and 2007 are neighbourhoods in the four central districts of the capital where overcrowding and old or dangerous housing is common; namely Dongcheng, Xicheng, Chongwen and Xuanwu. Large-scale evictions have also been carried out in several Chengzhongcun (literally, villages in the city), poor informal settlements comprising housing that has not been approved for construction, does not comply with building codes and typically is not properly serviced.
    They aren't evicting people to clear space for new development, they're evicting people from unsafe, overcrowded shanties.

    Several months leading up to the 1996 games, it was true that the Atlanta police were rounding up the homeless. But, the city was also paying to move them to shelters/YMCA. Although they did displace occupants of the downtown area, I would fathom an educational guestimate that it was less than 5,000 people. Far less than the 1.5 million people of China.

    Once the Olympics were over in Atlanta, and the city quit paying for the shelters, the homeless did return.

    The only thing that has changed since then, is better policing of the downtown Atlanta area and upholding the loitering laws in place since the early 70's.

    I've been to Centennial Park in the last year at night and actually felt safe to walk around. I didn't feel like that in the late 80's with a class at Georgia State University ending at 10pm and having to walk from there to the Five Points Marta Station.

    sure, just as soon as someone justify evicting 30 or more families to build a mall or walmart. You do have a point here, but I think you're exaggerating some figures and it's hurting your argument. You claim "30 or more families" are "evict[ed]" from their homes every six months to build a Wal-Mart or a mall. Somehow I doubt this is true for a number of reasons.

    First, the "big box" stores like Wal-Mart, Target, Home Depot, etc. try to find unoccupied land when they can because it's cheaper. Sure, in urbanized areas that's difficult or impossible, which is why their second choice is demolishing/renovating older shopping centers, warehouses, and so forth. There's several of these going on within ten miles of my home right now. Again, this is cheaper (and easier on the PR) than going after residential areas. The absolute last choice is a residential area because it's more expensive, more time consuming, and -- as you've noted in your argument -- it pisses people off sometimes.

    Second, I question your use of the term "evict." Evict means they're forcibly parted from their property. This does happen from time to time, and when it does it makes news. There have been documented cases of eminent domain abuse centered around these types of stores, and you're quite right to complain about them. That is your argument: the encroachment on private property rights by local city zoning councils (which are after sales tax dollars) and the businesses they "work" for (who want your sales dollars and pay politicians with campaign contributions). You hurt yourself, though, by claiming it happens "almost every 6 months" to 30 families. The aforementioned abuses are inexcusable, but they are much rarer than you claim.

    Third, you attempt to draw some equivalence between China displacing 1.5M people and our eminent domain abuses. That is a poor analogy for many reasons, not the least of which is that the Chinese have much more limited property rights than Americans do to begin with. Also, using your very own numbers, you claim 30 families are uprooted every six months in the U.S., and you claim it's been going on "for decades." By my calculations on your numbers (numbers I disagree with, BTW), the "fuckers in the USA" displace a maximum of 60 families a year. Assuming 3 people constitutes a family, that's 180 people per year. At this rate it would take over eight thousand years for the "fuckers in the USA" to displace 1.5M people, something the Chinese are doing in far less than a decade. Even that number pales when compared to the relocation required for the Three Gorges Dam project. Yet you seem to have a problem determining the difference in scale, morally equivocating one to the other.

    Like I said, your argument against eminent domain abuses are quite valid, but your exaggeration and hyperbole degenerates your argument into frothing at the mouth. What we're doing with eminent domain abuse in this country is bad, but what's going on in places like China is much, much worse...so much so that it really diminishes the more egregious abuse by trying to link it with the lesser abuse.

    I pretty much agree that the Olympics are going to be a huge expenditure with few tangible results, but I find it pretty unsurprising China is so gung-ho about this. In my opinion, hosting the Olympic games satisfies several agendas:

    • It's great for mianzi ("face"). Saving face, losing face, gaining face is a big deal in China. I used to think it wasn't that big of a deal and that it was really just another term for what Westerners go through, but it's got a surprising force in China. Even in Taiwan, which I would think is more westernized, I encountered behavior based primarily on face that defied common sense. It's not uncommon to ask for directions and get the completely wrong answer, not because that person was mistaken, but because they didn't want to tell you "I don't know." Winning in an Olympic event is big for China, but being the master of ceremony has to be even more prestigious. Add the home court advantage, and it's win-win!
    • It also fits China's massive industrialization and modernization agenda. The Three Gorges Dam and the intense infrastructure development in the west are just a couple of these large scale projects. Modernizing for the Olympics works well in Bejing: they've been purging the hutong (small residential collectives) for a while now, and under the flag of the Olympics, they can step up this agenda for an ostensibly noble cause. On a more positive note, it gives the government a good opportunity to make inroads against pollution. I visited a few years ago, and I was surprised at how clean the bus emissions were, given Beijing's dire pollution reputation.
    • In relation to the above, Bejing is a huge and marvelous city and is the symbol of the Chinese government. While Shanghai and Hong Kong may retain some of the glitter of being cities of international trade, there is no other city in China like Beijing, which blends culture, government, and military in such a peculiarly balanced way. Beijing means authority, and hosting the Olympics only adds to this majesty.
    • Finally, China strives for unity as much as it shuns dissent. The Olympics are a fantastic pretense for this. It makes the nation look strong as a whole, tells places like Taiwan "see what you're missing?", distracts the populace from idle mischief. In some ways, there's nothing wrong with this -- what's a little national pride? But in China, national pride often seems to be a bit more engineered than in Western countries, and the Olympics is no exception.

    I don't mean to be overly cynical about the whole affair -- I had several Chinese friends who were ecstatic when it was announced that China would host the Olympics, and I'm happy for them. But in response to the original post, the Olympics often seem to be huge expenditures that may or may not pay off. Not to be unfair to developing nations, but... why do we constantly have to build new stadiums to accommodate the Olympics? Can't we just use the old ones we built, and focus more on the games and less on the "boom and bust" economics of building the infrastructure every 4 years?

  16. Have to see the weather before you can modify it by lakshmanok · · Score: 2, Informative

    The way weather modification works (if it ever does: the jury's out on that one) is to find rain-bearing clouds and seed them so that the rain or hail falls somewhere other than where it would have normally fallen. The first thing, then, is to detect precipitation aloft. Pretty much the only way to do that is with weather radars -- satellite data is usually too coarse and not collected often enough.

    Does Beijing have a weather radar? Good thing you asked. The Chinese government recently bought a S-band weather radar so that they could use it for the Beijing Olympic games. Unfortunately, being communists (see: East Germany), they decided that the best place to install the radar was in the middle of the city so that it could be admired by the proletariat.

    Why is this funny? Because:

    (a) weather radars have a "cone of silence". The radar is on the ground and has to see up high with a relatively flat beam. This means that for around 30km around the radar, it doesn't see squat. In other words, much of Beijing is in the cone of silence of the "Beijing" radar. (For comparision, the weather radar that covers Dallas in at Dallas/Fort Worth airport, far enough away from the two cities to get a good view of the weather over both of them).

    (b) Most storms that hit Beijing move from West to East (as it does in most of the Northern Hemisphere). And to the west of Beijing are ... mountains. Which radar can not see through. And many of the storms do initiate over those hills.

    Bottom line? It's going to be hard to see the storms coming. Let alone modify the weather.
