Since operations have ended it’s now time to look back on some of the more interesting cases we’ve studied! The other night we woke up at 2am to head to the Orange site to fly our TLS. We were hoping to catch the transition to southwest winds with the possibility of catching a turbine wake.
However, the wind was very still for much of the night, so it was a good opportunity to try out long-exposure settings on our cameras!
Eventually we caught the southwest winds around 7 am and may have caught the wake around 9:30 am! The timing was a surprise to us as light convective activity would have usually started by then, making it much harder to see the wakes and waves. However, the convection was somewhat mitigated by a thick fog layer that came from down the valley and lingered for a long time. (lidar image from DLR)
The sun eventually came out over the ridge which brought an end to the nice stratification and so-called “golden night” in the valley.
We packed up our gear around noon and spent the rest of the day relaxing by the pool as a well-earned rest!
Keep your eyes glued to your screens as we begin to make our final posts!
