[FRIAM] Flying down the Ohio Valley

Sun Sep 30 02:03:13 EDT 2018

Hi, Steve, 

Your maps are absolutely stunning.  They give such a  powerful feel of the flows at different levels. It’s perhaps not ENTIRELY correct to say that 500 mb surface is a proxy for 18000 feet, anymore than the heights of the mountains and valleys are a proxy for sea level.  The 500 mb surface also has its mountain ranges and valleys.  

I wish we could find a small group of weather nerds and do a 6 session study group on skew-T diagrams.  

Those streamline maps, gorgeous as they are, of course VASTLY overstate what we know.  They are derived from skew t plots and these are extremely coarse-grained.  Here is the best index <https://www.spc.noaa.gov/exper/soundings/help/index.html>  I know of skew t plots, barely sixty sounding locations around the country. at 12 and 00 hundred hours, with occasional extras, often at Norman.   

Anyway.  Have to go to bed.  It’s good to be back.  Thanks for taking my question seriously.

while flying you might want to bring up this wind map and look at the different pressure levels:

Nick,

We can help you match the images clouds to the SkewT diagram with an Augmented Reality overlay. Right now it is a manual process but we hope to make it automated in the near future.

As I always have to go back and lookup how to read a Skew-T, is it true that this is from a single location (Norman, OK) and the x-axis is temperature and Yaxis pressure (proxy for altitude)?

For manual process:

Take some photos while you're looking out the window with your location services on (GPS). you may need to hold your phone next to the window to get a good GPS fix. And make sure your camera is "geocoding" your photos. It should store lat/long and altitude. The GPS is +- 100 ft with GPS and a little more accurate with barometer but in a pressurized cabin, the barometric altitude is not helpful. Right down your flight information as we can also pull up the flight track and match it to the time of your photo.

You can also try our beta of https://reatlime.earth while you're on the flight for encoding video and photos. On iphone open it in Safari. On Android, use Chrome. Take photos using the webpage. Android is a little better right now as we can use the hires image and record video instead of just images at video resolution.

To the Weather Nerds among you, 

I’ve been flying down the Ohio Valley for the last hour at 38kft.  Just crossed the Mississippi above St. L.  I sprang for the WIFI and so now I have a clear view of the bottom of the atmosphere out the window and a skew-t diagram <https://www.spc.noaa.gov/exper/soundings/help/index.html>  and weather map <https://www.wpc.ncep.noaa.gov/noaa/noaa.gif>  of the same on my computer screen.  There ought to be SOME relation between them!

Flying down to Baltimore from Hartford there were scattered to broken clouds arranged in “streets” and quasi streets and proto streets. But the interesting thing was that the streets were arranged with respect to each other all higgledy=piggeldy, even at what appeared to me the same layer.  This made me think that the “streeting” of clouds is not, as I had always supposed imposed on a layer by forces extrinsic to that layer, but something that “self organizes”  within the layer and that the layer I was looking at was at some critical state with trying to decide which way to street.  

Does anybody have anything to say about any of this?
