New views from space station/cold weather and global warming rant
February 18, 2010
Warning: I’m about to rant.
If I hear one more person say “look at this winter and all this snow… global warming… yeah right” I’m going to punch them in the fucking face. If you believe for one second that this winter’s excessive snow and cold weather in the southeastern US proves global warming is a myth, then you are simply solidifying your incredible ignorance and utter stupidity. There is a big difference between the terms “weather” and “climate.” Weather refers to the day-to-day changes in precipitation, temperature, barometric pressure, wind, etc… Climate refers to long-term, general trends in weather. We’re talking decades and centuries. That’s why global warming is referred to as “climate change,” not “weather change.” We will still have variations in seasons, even as global warming continues. Some winters will be colder and snowier than others, and some summer will hotter and drier than others. Some springs will be stormier, and some falls will have more hurricanes. These small-scale variations can be affected by long-term climate change, but there are many MANY other factors that come into play with small-scale weather events. One thing you may not realize about this winter (if you’re from anywhere east of the Mississippi) is that while we’ve had a cold, snowy winter in the east, most areas in the American west have had a very warm, dry winter. This is why there have been so many problems with Olympics. The mountains around Vancouver have not had as much natural snow as usual, and it’s also been warmer than usual. The direct reason for this winter’s weather is best described as a perfect combination of El Nino and the Arctic Oscillation. The AO is in a more negative phase this year than it has been in decades, which means the cold air at the northern latitudes is dropping farther southward into the US. This, combined with the very active and moist southern jet stream (which resides mostly over Mexico, Texas, and into the Gulf states), has resulted in a snowy winter for the southeastern US. This does NOT mean global warming is false! The average GLOBAL temperature is still warmer than normal. All this is explained in a much-less rant-y fashion at the Weather Underground blog. More details about the negative AO can be found in this AccuWeather article. Hey, Sen. James Inhofe, you just proved your massive ignorance and incompetence with your little igloo stunt next to the Capitol.
Rant over. Now for some much more pleasant science goodies…
The latest shuttle mission to the ISS, still in progress, delivered the new Tranquility node with a huge 7-panel window called Cupola, which was officially opened on Wed. Check this article on Universe Today for more details and to see pics of it. Look for many spectacular photos from this window to be released soon.
What would normally be a fairly unimpressive, routine rocket launch turned into a spectacular event last Thursday. NASA’s Solar Dynamics Observatory satellite launched on top of an Atlas V rocket. What makes this so special is the amazing coincidence of the rocket’s sonic boom (created as it surpasses the speed of sound) with its passage through the cirrus cloud layer. The weird looking ripples you see at about 1:50 into the video below are REAL. It looks like some kind of computer effect, but it’s NOT. There are still shots of them as well. What’s even more amazing is that another atmospheric phenomenon called a sun dog was happening at the time as well, and it appears that the sonic boom disrupted the ice crystals in the cloud, destroying the sun dog.

Skiing/weekend stuff
February 12, 2010
Megan and I are headed for my hometown of Kingsport this weekend to take advantage of this last snowstorm that dumped about 10 inches in the southern Appalachians. We’re going skiing at either Beech or Sugar mountain. Skiing in the southern Apps can be tricky due to the fickle winter weather around here… yes the mountains are always colder than other areas, but they still have to make most of their snow with machines, and sometimes they’ll have a long period of daytime highs in the 40s and nighttime lows in 20s, which means some of the snow melts in the day, then re-freezes at night, causing icy spots that are a huge thorn in any skiers side. But with this last snowstorm, and the fact that temps there haven’t gotten above freezing for several days, and won’t until sometime next week, the slopes should be pretty nice & powdery this weekend.
That means I won’t be out & about seeing shows/partying/etc… this weekend, but that doesn’t mean you shouldn’t be.
The big show tonight is Tortoise with Disappears at Exit/In. Also: Neil O’Neil and Max & the Wild Things at the 5 Spot.
Saturday- Oblio, Shoot the Mountain, Deleted Scenes, Steve LaBate at The Basement.
Also on Saturday, two things will be coming together that I honestly thought I’d never EVER say in the same sentence: Infinity Cat and Vanderbilt. Yes, according to Nashville’s Dead, Infinity Cat bands Natural Child and Daniel Pujol will be playing at Vandy’s McGill Hall (that’s a dorm), along with a band called Colossi. I have no idea if Colossi is associated with Infinity Cat. Pretty crazy huh? Although, being a Vandy employee, I do know that McGill Hall is definitely the extreme exception to the typical Vandy kid stereotype. It’s basically where most of the students who don’t fit into that Greek/trust-fund-kid stereotype live. So while Vanderbilt and Infinity Cat definitely have a bit of an oil & water vibe, McGill and Infinity Cat seem much more like peanut butter & jelly.
Have a great weekend!
Snowpocalypse: Part Duex/NASA rumors
January 28, 2010
Here we go again. I recommend investing in Kroger stock this year, because they’re gonna get a big boost in sales in TN from all these “snowstorms” wherein a meteorologist utters the word “snow” and 75% of the population immediately clears the milk, bread, and egg isles. (Apparently people only eat french toast during snowstorms?) As usual, I’ve been monitoring the progress of the forecast and find it interesting that the NWS hasn’t issued the winter storm warning yet, only a watch. I’m sure the warning will come, but it’s kinda funny that they’re hesitating, no doubt because of the giant snow fail from a few weeks ago. (To be fair, some areas around the midstate did get something close to the forecasted amounts, though no one really got the full 2-3 inches that was initially forecast…) This system is a little different than the last one, however. This one will most definitely have enough moisture to generate the 3-5 inches, unlike the last system which had moisture “issues.” The big limiting factor with this system will instead be temperatures. Nashville will literally be right on the dividing line between having an ice/rain mix and having an all snow event. If this system decides to track just 50 to 100 miles further north than the models think it will, that will cause more warm air to advect farther north, and we’ll end up having mostly rain friday changing to a little snow on the backside fri. night into sat. morning. If it decides to track slightly further south, we’ll have all snow, but much less of it, and areas to the south of us could actually see more snow than Nashville does. This system has a little better chance of “success” in giving us a good ol’ fashioned snowfall than the last one, but I wouldn’t place any bets yet.
Big rumors abound in the blogosphere about Obama’s budget proposal due to land in Congress on Monday. The biggest rumor is that it will completely cutout NASA’s Constellation program, which is the rocket system currently under development to not only replace the Space Shuttle, but also put men back on the Moon. I reported many times on the progress of the Augustine Commission and its recommendations for how NASA should proceed given that its current “trajectory” was financially unsustainable. One of the options they proposed was to eliminate the Constellation program and let commercial spaceflight companies like SpaceX takeover the duties of getting astronauts to the International Space Station and other low-earth orbit missions. I have a feeling that if the budget really does cut the Constellation funds, that’s where we’ll be headed next. Honestly I think it may not be a bad idea, because it would allow NASA to focus more on getting man further out into the solar system, and eventually to Mars. I tend to agree with Dr. Phil Plait’s (the Bad Astronomer) sentiments on the issue (as usual) but I’m not in total agreement with him that we should still go back to the moon. But then again, he’s the astronomer with a Ph.D and I’m not. For even more info, check out Universe Today. Check those blogs again on Monday afternoon, as I’d say they’ll be able to update waaaay sooner than I will once the actual budget info is released.
SNOW FAIL
January 7, 2010
This has happened so many times before, you’d think forecasters would get a clue. As a weather nerd I’ve followed the same models the forecasters use, they are easily found on the NOAA/NWS website. For some reason, the models often fail to take into account just how ridiculously DRY the air is with these Canadian arctic highs, and how stubborn it can be. We’ve had a very cold and VERY DRY last few days because we’ve been under the influence of a high pressure center that slid down the midwest into the southeast from Canada. The low pressure system and associated front that is currently passing through middle TN is ahead of yet ANOTHER Canadian DRY airmass. Even though there is some moisture associated with this front, there isn’t enough to overcome the insanely dry air at the surface. There’s plenty of snow flying around waaaay up there, but it’s evaporating as it falls through the lower layers of the atmosphere via a process called sublimation. As of about 10am, we are finally starting to see a few tiny grains of snow making it to ground in downtown Nashville. Other areas to the north and west have already seen about 1/2 inch, but I doubt Nashville will even get that much. It won’t be over till the front pushes on through later this afternoon, though. The only thing we can be 100% sure of with this system is that it will be FYAO cold this weekend.
UPDATE 3pm: Snowflakes finally started fleshing out around noon in downtown Nashville as moisture finally reached the lower levels, but it still has only amounted to a dusting.
This has happened before, and I just don’t see why conventional wisdom never makes its way into these forecasts sometimes. They rely too strictly on the computer models. To the meteorologists defense, however, winter weather has always been, and always will be VERY fickle and hard to forecast in the southeastern US. Also, the science of meteorology is always a work in progress, and any forecast past 1 day or so is at best an educated guess. No matter how sophisticated our computer models get, they will never be near as complex as the forces at work in our atmosphere, and until we devise some method of actually controlling the weather, a 100% accurate forecast past 12-24 hours is simply impossible. For more info on why snow is pretty hard to come by in TN, see my post on the subject from last year.
That being said, here’s my conspiracy theory: Kroger is in cahoots with the NWS and all other forecasters in the southeast. They promise them a cut of the massive profits from all the bread, milk, and eggs sales in exchange for inflating the snow amounts.
KIDDING!!!
Static electricity/astronomy updates
January 6, 2010
January is often a time for lots of updates from the world of astronomy, because it’s when the American Astronomical Society has their yearly conference/meeting. This year’s is a big one, with lots of news regarding exoplanets. Unofortunately, no Earth-twins have been found yet but there are some other interesting stories from Kepler and many other sources. Some highlights so far:
The Kepler mission has found its first batch of exoplanets, all of which are gas giants similar to Jupiter (though one is reportedly more like Neptune) orbiting very close to/quickly around their parent stars. It’ll be a few years before it finds anything else, because anything else takes a lot longer to orbit. Since Kepler is specifically looking for transiting planets (the planet passing directly between its parent star and us) it has to have 3-4 transits to be absolutely sure of its findings. Since planets like ours take a year or more to orbit… well, you do the math. It even found one gas giant that has the same approximate density as sytrofoam. (Via NASA and NewScientist)
Another interesting tidbit to come out this year is a much clearer picture of just how common solar systems like our own are in the universe/galaxy. According to astronomers from Ohio State University, who were heading up a larger collaborative effort called MicroFUN (micro-lensing follow-up network), about 10–15 percent of all stars have planet systems like ours (meaning a few gas giants orbiting far out, with probably a few small, rocky planets in closer). 10-15 percent may seem like a small number, but when you consider the overall vast number of stars just in our own galaxy alone, you’ll realize that even 10 percent equals hundreds of millions of solar systems. It should be quite obvious now that there are other worlds out there very similar to our own, we just haven’t found solid evidence of them yet, so we can’t be 100% sure. But I am confident the Kepler, the CoRoT mission, or maybe even a ground-based telescope, will find one within the next decade. (Via EurekAlert! and Space.com)
Here’s a little bit of everyday science for you:
We’ve all been annoyed when we get out of our cars or walk across a carpeted room in the winter time and shock the #&*$@! out of ourselves on the door/other metallic object. So why the hell does it always happen so much more in the winter? It has to do with the humidity. Especially in the eastern US, the winter months are much MUCH drier than the summer ones. (Remember that Relative Humidity is NOT a direct measurement of how much moisture is actually in the atmosphere, go by the dewpoint- the lower the dewpoint, the less moisture is in the air.) Colder air has less moisture capacity than does warmer air, thus the winter months are very dry. Well all know that static electricity is the buildup of an electric charge in our bodies and/or clothes due to simple friction. During the summer months when the air is more humid, the moisture in the air allows those charges to constantly dissipate because we all know water is a good conductor of electricity. The static electric charge never has a chance to build up because it’s constantly “seeping” away into the moist air. In the winter, the dry air does not conduct and “seep” away the static electric charge, allowing it to build up until we reach for something metallic such as a doorknob and POW! the electricity instantly discharges in one big spark and we get shocked.
May ’08 ‘stache
January 5, 2010
So it looks like the ladies of Nashvillest decided to make my May 2008 ‘stache famous by putting my ugly mug on their blog this morning (probably yesterday morning by the time you read this). Due to the fact that I’m in the midst of moving into a new house with Megan, I haven’t kept up with the blogosphere for the past few days. I actually find it quite hilarious. There are much worse photos of me out there, so I can’t really complain. I could try to find a funny picture of Morgan or Christy (though I’ve only actually met Christy in person, ha…) but no one would really care because let’s face it, they have at least 10x as many readers because they’re a “real” blog. If you don’t read Nashvillest, you’re either a) several years behind the curve in local interwebz happenings, or b) not from Nashville. But even if you aren’t from here, there’s plenty of interesting stuff on there for non-locals, so get over there!
I hope everyone is prepared for the Great Nashville Blizzard of 2010. (A.K.A. a couple inches of snow) I really can’t wait to see Nashville drivers on Thursday. I’m probably going to take a video camera around with me everywhere I go…
Yellowstone photos/creepy apple video
September 1, 2009
Grand Geyser
After way too long, I’ve finally gotten the photos from our trip to Yellowstone National Park on my flickr. We had a great time and I will never, ever tire of seeing that place. It is literally one of the most fascinating places on earth and everyone should go see it. It had been 9 years since I last saw it, and while reading some of the information plaques I realized that some major geologic changes had taken place just since the last time I was there. The place is just teeming with hydrothermal activity and is always changing. Not to mention that the scenery is absolutely gorgeous. So please go take a look at the photos. We also visited Mt. Rushmore, the Badlands, Grand Teton Park, and came back by driving through Colorado and New Mexico, making a quick stop at Philmont. Not only was the land beautiful, but we also got to see a pretty nice light show in the sky almost every night we were in Yellowstone. The Perseid meteor shower peaked while we were there, and with the absence of light pollution from cities, we could see them quite well. (That is, until the gibbous Moon rose around 11pm…) Literally, we could look up at any given time between sunset and Moonrise and see a meteor within a minute.
Some other random scientific tidbits:
A team of Swedish scientists, with the help of some other Chinese researchers, have discovered a very exact location and date for the birthplace of dogs. Apparently dogs originated from a group of tamed wolves about 16,000 years ago in an area of China south of the Yangtze River. Sadly, it’s also thought that those dogs met their fate in the stomachs of humans. (Via EurekAlert)
By now I’m sure you’ve heard of Apple’s new OS Snow Leopard. It’s not a total upgrade, since the last major update was called Leopard, but it is a significant advance in how the computer utilizes those multiple-core processors that have become standard over the past few years. It all boils down to the OS providing a way for applications to run multiple processes in parallel, or at the same time. Gizmodo has an article that explains it quite well, and I suggest reading it. I’ll probably be upgrading to Snow Leopard pretty soon.
And now I’m simply going to leave you with this incredibly creepy video using time-lapse footage of a rotting apple. No pun on the previous paragraph intended. (Via Kottke)
new 5 Spot website/10 most extreme places on earth
July 30, 2009
Everyone’s favorite East Nashville dive/hangout the 5 Spot suddenly has a new website! Who knew? It’s good, because they needed one. Myspace used to be the only place to find their listings (other than the Scene and MetroMix) and now that it’s going the way of the dinosaurs, they needed another online presence. (Via Out The Other on Twitter)
I was delighted to see that the trailer for The Fantastic Mr. Fox is now out. Visually it just looks wonderful (as all Wes Anderson films do), and with the voices of George Clooney, Bill Murray, Jason Schwartzman, Owen Wilson, and Meryl Streep? YES all the way around. (Via Yewknee Twitter)
Oddee.com is hit or miss on their posts sometimes, but today they posted a blog about 10 extreme environments on Earth. Pretty interesting. They need to hire a copy editor.
Today’s a pretty slow news day, so that’s all I have for you. Weekend stuff coming tomorrow.
Attention bands everywhere: the Next Big Nashville deadline for entry was extended until this coming Friday. It was originally today, but last Friday they announced the extension. So get over to American Songspace and apply if you haven’t. It’s only ten bucks!
Those Darlins just keep making bigger and bigger news stories. This time they got a mention on CNN and the New York Times! Check out CNN.com and watch the video clip. They talk about Hannah Montana first, then mention the Darlins at about 2:50 into the clip. Then check out the NYT review here. They also got written up on Brooklyn Vegan for the 368th time….
Tonight is Nashville Cream’s 70’s cover night at Mercy Lounge. It’s like an 8 off 8th in that there’s 8 bands and they play about 3 songs each, but all bands are doing covers of songs from the 70’s. It’s totally free and 21+. It’ll be a blast so come on down.
Oddee posted a blog about 10 very strange bars. My favorite is the bar made of ice. Pretty awesome.
From the science world…
The launch of Space Shuttle Endeavour was scrubbed AGAIN yesterday due to storms in the vicinity of the launch area. They’re going to retry the launch at 6:51pm EDT tonight, but the forecast is still pretty iffy. Basically any afternoon/early evening launch time during the summer months is a shot in the dark because storms pop every afternoon in Florida due to the interaction between the hot/humid air over the land and the cooler seabreeze coming in off the ocean. Basically they’ll just have to get lucky.
In other NASA news, a really cool interactive flash application is up on their website. It’s a panoramic view made of images taken during the Apollo 11 moon landing (except for the image of the Eagle lander, which is obviously CG). You can scroll around from several different viewpoints. In case you didn’t know, this year is the 40th Anniversary of the moon landing.
New Brendan Benson/Jenny Lewis video/earthquakes
July 10, 2009
Brendan Benson wasn’t nearly as well-known prior to joining up with Jack White in The Raconteurs. He had out some solo albums that were great, but his new album is looking to be far beyond “great.” If the rest of the record is as good as this first track “Don’t Want To Talk,” then it could easily make its way into my top 5, maybe even 3 albums of 09. This song is just packed full of awesome. RCRD LBL posted it for download today, and you’d better go grab it. NOW.
Jenny Lewis has a new video out for the song “See Fernando” from her latest album Acid Tongue. Stereogum posted it yesterday. It’s very visually pleasing and let’s face it… Jenny Lewis is just pretty, though she doesn’t actually have as much screen time as one would hope… I got to see her at Bonnaroo and thoroughly enjoyed her set, especially when Elvis Costello joined her for “Carpetbaggers.”
As for this weekend… we’ll probably stay in tonight and catch the new episode of Eureka on SyFy. Saturday I’ll be doing a photobooth for the Miller Made Music/Lightning 100 free show at Exit/In with the Non-Commissioned Officers, Mean Tambourines, Perrin Lamb, and Mikky Echo. It’s a free show so you have no excuse not to come. Then on Monday be sure to check out the 2nd installment of the Nashville Cream decades 8 off 8th series. This one will cover the 70’s and I heard Caitlin Rose and Tristen’s covers are gonna be especially awesome.
I’ll the science to a minimum today. All I have to say is this:
The unusually nice weather we’ve been having lately is about to come to an end. These past few weeks have been a few degrees cooler than usual, and temps even stayed shy of 90 for a string of 8 days. But the biggest story was the humidity, or absence thereof. It’s been agreeably dry lately, which makes the heat MUCH more tolerable. The reason for this was that the Bermuda High Pressure System which normally dominates the summer weather in the southeast was relatively weak and further east than normal for this time of year. The clockwise circulation around the Bermuda High channels hot and humid air from the Gulf of Mexico right into the American southeast almost all summer long. This is what causes our typical “dog days of summer” weather, and sadly it’s about to return westward and re-establish itself over Bermuda. Also, El Nino is officially here, so get ready for a wet winter.
Have a great weekend!
