Freier Bericht

Visibility wise I had better days for sure. It looked murky all day, but conditions were good, the ridge worked, a bit less in the morning (but the sun was already heating the slopes and this helped), and stronger afterwards. I was really happy to find this wave as it wasn't marked by anything (no rotor or lenticular) and it's quite easy to fly past it on the ridge. Also, it resonated a bit more westerly than usual - and it makes sense with the South East wind component. After I reached the top of the wave I could fly towards Suntel without loosing too much height, but there I quickly lost what I gained flying upwind trying to find a wave in front of a fake-rotor. The wind was quite variable during the day. I encountered: South-East, South and South West Wind. In the morning the wind was more from South-East, and in the second part of the day it turned South, South West and increased in strength, with the arrival of the cold front. This can be seen as well on the barogram (check OLC link) before and after the wave climb. The touching area of the cold front with the older airmass was marked by a nice convergence line, oriented South-North but climbing there was not possible (I tried but I did not succeed). Thanks to the Porta Westfalica aeroclub members which made this flight possible.
