Iknow that seasons are caused by the Earth's axial tilt - in summer, latitudes away from the equator receive more surface irradiance (power per unit area), and vice versa in the winter, because of the closer-to-normal incident angle of the sun's rays (it's higher in the sky). It's now spring at my latitude, and I'm starting to feel the "beat" of the sun again - the heat on my skin and clothes caused by the infrared radiation from the sun.
But I started to wonder why I don't feel as much heat on my body and clothes during the winter. Even if the sun is lower in the sky, I can still stand in such a way that my shirt is perpendicular to the direction of the sun, which should maximize the irradiance on my shirt. In fact if I'm walking along, my chest is closer to perpendicular when the sun is lower in the sky - so shouldn't I feel more infrared heating in the winter than in the summer?
Is there something atmospheric going on - like the fact that when the sun is lower in the sky the radiation is traveling through much more atmosphere before it gets to me? Or am I missing something else entirely? Or is it just a sensory illusion caused by the fact that the ambient air is cooler in the winter, making the infrared heating less noticeable?
The gases in the atmosphere absorb the infrared radiation thus dissipating the incoming heat. To see how much role does atmosphere play when it comes to stabilising the heat, you could consider a close example without the atmosphere - the moon. It's said that the temperature of its surface can heat up to >$100^\circ$ C, as well as fall to extremely low temperatures.
As an example of the lower atmosphere layers plaing a good role, you could consider being on a mountain - despite the fact it's not really significantly higher above the "flat" ground level, the sun here is really more intense, while the temperature is lower (I have been up in the mountains and I know that weird feeling).
As for the illusion, I believe that if anything, it's about the thermoregulation of the body. I think that an example of you hot bathing and then going out to the cold weather - you aren't noticing the fact it's cold outside for a while; i.e. not really dependant on the actual radiation here.
The radius of Earth is approx. $6371$ km. The "end" of the atmosphere we'll pick at the height of 100 km (see Krmn line). Note that those numbers are not really relevant, since we're going to get the ratio of length of the path the radiation is going in the winter and in the summer.
Inspired by route creator Josh Hejl. We thought this would be a fun way to celebrate our seventeenth wedding anniversary, Mixed team, male-female, unsupported. We left our house on bikes around 0410 and biked a short distance to our route start-stop point on smith road. Between the two bikes and packs we had all the gear and food we would use for the day, with the exception of water refills which were obtained from various mountain streams en-route. We then rode to, and climbed Government peak in a rather cold rain, finishing our descent very wet, muddy and a little bruised from falling so many times at the 3.5 hr mark. A cold ride to Pioneer peak with lessening rain helped to dry us out and allowed a more pleasant ascent/descent of Pioneer. Round trip time on south Pioneer peak was about 5.5 hrs, with glimpses of sunshine through the clouds and fog. Fresh bear and sheep sign near the top reminded us we had more animal than human company for most of the day! That changed as we survived a busy bike ride--back out knik river road and over to the safety of the bike path on the old glenn highway--to finally arrive at smith road trailhead. Shortest route up McRobert's creek led us to our final summit (Matanuska) of the day and then the freight train got rolling as we blitzed back down McRobert's valley, finally close enough to the end that we could really run! Round trip on Mat peak was just over 3.5 hrs. We hit the bikes at the trailhead and a 32 mph descent led us to our start/stop point and we were done. Round trip 15 hrs 16 min.
Route notes: Josh started and stopped at his house in downtown palmer which is near the shortest routes between peaks. We elected to start/stop on the route itself, thinking this allows anyone to choose their own starting point anywhere between the three peaks, so long as they return under their own power to the same point at the end. The biking comprised much less than 50% of our total time as per FKT website guideline--about 3.5 hours total of the 15 plus hour trip. We had no pacers, and no company besides each other, except for passing by two hikers on Pioneer and a couple groups on Matanuska. We ate four egg burritos, a bunch of peanut butter/maple syrup mix, some chips, pickle juice and too many bottles of tailwind--all food carried from the house. Finally, due to previous bad decisions in his life, Ben was stuck riding on a single speed cyclocross bike with his children's back packs strapped to it as terrible, improvised saddle bags.
The most common (yet subtle, yet disastrous) mistake I see in tournament Magic is the misassignment of who is the beatdown deck and who is the control deck in a similar deck vs. similar deck matchup. The player who misassigns himself is inevitably the loser.
You see, in similar deck vs. similar deck matchups, unless the decks are really symmetrical (i.e. the true Mirror match), one deck has to play the role of beatdown, and the other deck has to play the role of control. This can be a very serious dilemma, if, say, both are playing aggressive decks.
The same comparison can be made when two control-based decks slug it out. At the same PTQ, I was playing High Tide against what is normally a dangerous matchup for me, CounterSliver. My opponent was running the usual array of Slivers, Worship, and permission, as well as Cursed Scroll. He made the mistake of thinking he was the control deck.
After playing a turn-2 Crystalline Sliver, he followed up two turns later with Worship, so I Stroked him out. (I killed him the first game with Palinchron, and because I mostly showed him some Disrupts, Force Spikes, and card drawing, he may have thought I was more creature heavy).
1. Who has more damage? Usually he has to be the beatdown deck.
2. Who has more removal? Usually he has to be the control deck.
3. Who has more permission and card drawing? Almost always he has to be the control deck.
If you are the beatdown deck, you have to kill your opponent faster than he can kill you. If you are the control deck, you have to weather the early beatdown and get into a position where you can gain card advantage.
For an example of correctly determining who is the beatdown deck and who is the control deck, look at the Sligh vs. Sligh match between Price and Pacifico at the top 8 of the 1998 U.S. Nationals. Although on the surface, the two players seem to be playing very similar decks, there are major design differences:
Had Dave tried to race Pacifico, he might not have won. When two players are just blindly throwing their creatures into one another, the one with more damage-oriented cards is going to win the race (but I figure we expect good Sligh play from the King of Red).
Which deck has more damage? Suicide Black. It runs many high power-to-cost creatures, like Carnophage, Sarcomancy, and sometimes Flesh Reaver. Sometimes it has stuff like Hatred. It damages even itself.
The Zoom Beatdown is approximately 3 1/4 inches long. It features a blunt-nosed, thicker end and tapering rounded tail. That profile does more than anglers would think at first glance.
The Zoom Beatdown is firm for better rigging on a ned head but soft enough that the bait has some undulating on the fall, a bit of tail wag when you shake it and the bait is a bit thicker and heavier in the head section so it glides through the water.
Where I have found the most success with the Zoom Beatdown has been fishing it around pods of small baitfish on this late spring and early summer. The fry and bait on the lake is all very small around 1 to 3 inches. This is a perfect profile for bass that are roaming around places like boat docks, flooded cover and even just around shade hoarding pods of small baitfish.
Beat Down is a song by music producers Steve Aoki and Angger Dimas, featuring vocals from Australian rapper Iggy Azalea.[2] The song was included on the re-release of Aoki's debut studio album, entitled Wonderland (Remixed), which was released on July 10, 2012.
Aoki released his long-awaited debut studio album, Wonderland, on January 10, 2012, featuring guest vocalists and musicians LMFAO, Kid Cudi, Kay, Travis Barker,
will.i.am aka Zuper Blahq, Wynter Gordon, Rivers Cuomo, Lil Jon, Chiddy Bang, Lovefoxxx of CSS, Big John Duncan (former guitarist of the punk band The Exploited), and others, through his record label Dim Mak. A remix album was released shortly after, on July 10, 2012, Wonderland (Remixed), featuring a new original track that would become the lead single of the project, "Beat Down," with fellow Indonesian electronic producer/DJ Angger Dimas and also featured up-and-coming Australian rapper Iggy Azalea, who had been featured on the cover of hip-hop magazine XXL's buzzed-about annual "Top 10 Freshman List" and announced signing a deal with Southern rapper T.I.'s Grand Hustle Records.[citation needed]
Becky Bain of Idolator claimed the track is "a solid tune that is ready to pump you up" and complimented Azalea's guest appearance adding that "the Aussie rapper lays down some serious flow."[2] DJ Booth also praised it saying, "If you're a fan of EDM and a lover of 808s and snares, then you'll probably wear out the repeat button after listening to this single. Iggy does surprisingly well with the complex track as she professes that she's well versed in the art of the beat down with lyrics like, "It's a party on your face and I'm about to dance on it","[3] while Noisey drew comparisons to Major Lazer's 2009 single "Pon de Floor".[4]
