A nice case study from the evening of July 3 & 4 UTC

Is speed up in the rotor region further into the wind farm due to turbines?




The wind directions have not been rotated to adjust for any instrument alignment errors.




Look at all that extra turbulent energy downwind of the turbines!

Winds are blowing and wakes are propagating!

Tonight (4 July 0000 UTC+) we will likely have our first case study!

When Branko and I visited the windcubes this afternoon to install the modem at A2, we noticed winds were rotating from NEly to SEly and very slow, ~ 3m/s. 

This evening, we have perfect SEly winds. At A3, we can clearly see the wake in the profile 

especially when compared to the clean profile at A1:

Veer has not yet developed under the LLJ, but it's great to see some wakes!

The radiometer is not yet online (we will try again to install a US Cellular USB modem on Friday) but is collecting data.
