As I understand, a balloon is sent up from the local weather station, twice a day. This balloon has a package of sensors attached to it, recording a &#8216;slice&#8217; of the atmosphere including temp, wind direction, and other information. Basically it&#8217;s a tool for atmosphere analysis. More info about upper are sounding can be found <a href=\"http:\/\/weather.unisys.com\/upper_air\/skew\/details.php\" target=\"_blank\">here<\/a>\u00a0or <a href=\"http:\/\/en.wikipedia.org\/wiki\/Atmospheric_sounding\" target=\"_blank\">here<\/a>.<\/p>\n<p>And basically, this is what&#8217;s happening here, except this is quad copter doing the &#8216;measuring.&#8217; As we&#8217;re watching Michael&#8217;s video, we notice as the copter elevates, the temperature drops. And one of the things I learned from meteorology school about 14 years ago, as well as experienced personally when flying (no I&#8217;m not a pilot), on average per 1000ft in elevation, the temp drops about 5 degrees, but is not always the case.<\/p>\n<p><span class=\"Apple-style-span\">So knowing a little about the weather and seeing the telemetry data on screen, I thought it would be neat to graph this.<\/span><\/p>\n<p><strong>Warning!

There are much smarter folks out there that can explain much greater detail about &#8216;warm noses&#8217; and varying temperatures with height and why all of this happens.
