I'm new to paragliding and I know that people use apps like windy to check if the wind condition is allright for a flight.
Unfortunetly I do not know much about weather forcast.
I know what the symbols in the airgram mean. But there is a column of these symbols for each observed hour. What does that mean?? How can this diagram help me decide if the weather is suitble for flight or not?
@p1rate Hi! Symbols illustrate wind speed and direction.
See this picture: https://en.wikipedia.org/wiki/Weather_map#/media/File:Wind_barbs.gif
How can this help you to prepare flight? It depends on what kind of flying you do (thermal flying / ridge flying) and on the terrain where you want to fly.
And what do these numbers 700h 800h 900h etc mean?
pressure levels in hPa (hectopascal)
As the average pressure on sea level is 1013 hPa
700 h is 3000 high (10.000 ft)
800 h = 1950m=6400ft
900 h= 990m=3250ft etc
