Thank you for that, BT. Unfortunately, the paper contains a load of
formulae, and when I graduated (in the days of big collars and flared trousers) I swore I would never look at another formula
What is needed is several examples of actual tephigrams, and the interpretation. You could write a nice little web article - I have never seen such a thing that was clear practical and readable.
BTW there is another form called a skew-t; you can get them from
http://weather.uwyo.edu/upperair/sounding.html
Select Europe, then GIF/Skew-T. It's a tephigram but slightly skewed. These are real baloon ascents; rarely useful due to being just twice a day.
Being an
ex employee of a weather provider, there should not be a conflict of interest
