12:34:24	 From Andrea  N. Hahmann : Are the wind turbines only in the D03 domain? Did you run with 1 way or two way nesting? Maybe you will answer this soon. Could you ask Eigil if he does not?
12:35:34	 From Andrea  N. Hahmann : Yes, thanks
12:35:50	 From Andrea  N. Hahmann : In 1-way they will.
12:38:17	 From Gregor Giebel : 500m distance with 168m rotor diameter is only 3 d distance - this would not really be done in reality.
12:38:39	 From Gregor Giebel : Both due to wake effects and due to high mechanical loads on the turbines.
12:39:09	 From Bettina Meyer : @Gregor Giebel: Why is the mechanical load on turbines influenced by the spacing?
12:41:03	 From Gregor Giebel : Because the turbines create turbulence, and the wake is still visible from the individual blades at 3 d, while it is better mixed at 6 d. I would rather say, 6-8 d is typical.
12:43:49	 From Bettina Meyer : Thank you!
12:44:44	 From Andrea  N. Hahmann : To elaborate from Gregor. Turbulence within the wind farm will influence the loads on the turbines downstream.
12:48:00	 From xiaohua  : do you see dependence of wind reduction distance on model resolution?
12:49:20	 From Jens Hesselbjerg Christensen : How close to the wind turbine area is the lateral boundary? Is the model domain the one shown by the map?
12:50:02	 From Gregor Giebel : Interesting! Have we ever observed the increased precipitation at existing farms? This would have an influence on leading edge erosion (where rain destroys the front edge of the rotor blades). 
12:50:50	 From Andrea  N. Hahmann : Yes, Gregor. both rain and increased wind speed.
12:51:30	 From Andrea  N. Hahmann : Not increased, but large.
12:58:00	 From Jens Hesselbjerg Christensen : Sorry - I have to leave for another meeting. Thank you for a very interesting talk Simon
12:58:10	 From Bjarke Tobias Olsen : In this version of WRF (4.0.1?) there is a bug in Fitch, which means TKE generated by the turbines is not advected downstream. How do you expect results to change with more advected TKE?
12:58:28	 From Kaushik Das : Thank you for nice presentation. I need to leave now.
12:59:17	 From Kasper Tølløse : Thank you for a very nice talk. Unfortunately, I have to leave now.
12:59:23	 From Gregor Giebel : LES shows a peak at row 7 and 12. Of course, running that many turbines with LES is prohibitive...
12:59:27	 From Gregor Giebel : Global trends in the performance of large wind farms  based on high-fidelity simulations by Søren Juhl Andersen, Simon-Philippe Breton, Björn Witha, Stefan Ivanell, and Jens Nørkær Sørensen https://wes.copernicus.org/articles/5/1689/2020/
13:10:12	 From Andrea  N. Hahmann : Jana will be talking about the waves and wind farms in the DAMS meeting on Monday.
13:10:23	 From Gregor Giebel : It's good to see that at least some of the Train2Wind students are here (Emily). In the Train2Wind project, we are investigating "how large is an infinite wind farm", or a bit more scientific, when is the ABL again in equilibrium with the wind farm below. See www.Train2Wind.eu. From your results, it seems that you need two degrees longitude...
13:11:49	 From Gregor Giebel : Re: shipping. The process of Marine Spatial Planning gives you belts for shipping and other uses of the sea, where the wind can recover a little.
13:11:55	 From Shuting Yang, DMI : Thank you for the very interesting talk. I have to leave. Bye
13:11:56	 From Peter Langen : Need to leave. Thanks Simon!
13:16:49	 From Jibran Khan : Thanks a lot for this nice presentation, need to leave. Good Christmas everybody :)
13:24:03	 From ssy : Thanks Simon, this was a very nice presentation. Have to leave.
