Wait, there’s more! It’s how they’re showing up that’s interesting. They make radar returns that look a lot like tornadic vortex signatures (TVSs). On radial velocity imagery, the wind farms appear like dense, adjoining red and green couplets. The red indicates motion away from the radar; green means motion toward the radar site. Put them close together and you’ve got a marker for rotation. As in, “we aren’t in Kansas any more.”
I’ll wager that word of this spreads fast. Hope everybody scoping out Nexrad during a preflight briefing gets the chance to learn where these wind farms are…..
