we went from shoreham to compton abbas and back today,and yes it was turbulent with up and down currents associated with the cloud formation,a glider pilot friend once told me about 'streeting' where youll get a line of clouds with associated updraughts, and then the blue bits with the down draughts, my student found it a challenge with often having to use large power changes to stop climbing, and then having to apply power to stop sinking!
just one of those days.
