There are thousands of turbines in the California desert. Their job is to generate and dispatch clean power.<\/p>\n
One of the green energy giants growing in size and output is the San Gorgonio wind farm. But it’s bringing changes to the local climate <\/strong>along with its growth.<\/p>\n The land under the blades started behaving erratically.<\/p>\n Suddenly, the turbines weren’t just harvesting the wind anymore<\/strong>. The actual physics of the environment were shifting. <\/p>\n How did the farm end up changing the climate so drastically?<\/p>\n The conditions in the San Gorgonio Pass are as fierce as you’d expect from a desert<\/strong>. The thousands of turbines in the area are designed to last through the incredible heat and the Californian winds.<\/p>\n It took some marvelous engineering to install such an expansive presence under such intense conditions. <\/p>\n The volume of clean electricity generated<\/strong> by the new-age energy technology is impressive. <\/p>\n And it’s all done on land that would be used for nothing otherwise.<\/p>\n But there are consequences to this immense generation activity<\/strong>. <\/p>\n Researchers started picking up subtle anomalies as the maze of turbines grew denser. Precision weather instruments detected microclimate shifts. But only around the spinning rotors.<\/p>\n Then the ground below the blades started behaving in new ways<\/strong>. And it wasn’t simply down to a natural regional climate trend.<\/p>\n Something man-made and immediate was changing the weather\u2014an inadvertent effect of harvesting it.<\/p>\n The mechanism behind the shift wasn’t all that easy for scientists to figure out. What goes on when thousands of enormous rotors spin simultaneously<\/strong>?<\/p>\n The anomaly in the San Gorgonio stats was obvious at a glance. <\/p>\n Two distinct, conflicting trends<\/strong> were picked up by meteorological sensors.<\/p>\n Near-surface temperatures dropped during the blistering hot days. Beneath the massive turbines, the ground was markedly cooler than the open desert nearby.<\/p>\n The system flipped at night.<\/strong> Normally, the air would cool rapidly as soon as the sun sets. Instead, it remained stubbornly warm with elevated temperatures throughout the dark hours.<\/p>\n This was a complete inversion of typical desert climate behavior.<\/p>\n And the fluctuations were strictly local<\/strong>, according to the study “Impacts of Wind Farms on land surface temperature,” published by Nature Climate Change<\/em> in ResearchGate<\/em><\/a>.<\/p>\n The phenomenon could not be put down to global warming<\/a>, seeing as the disruptions were immediate. What was it about the motion of the blades that flipped the thermometer? <\/p>\n The answer is a phenomenon called “wake mixing”<\/strong> that has to do with the atmospheric boundary layer.<\/p>\n The spinning blades mix the layers above the ground.<\/p>\n The rapid cooling of the desert floor at night means a thin layer of cold air is normally trapped at the surface<\/strong>. A warmer layer of air is left directly above.<\/p>\n The blades chop right through the two layers of the atmosphere.<\/p>\n The rotors physically drag the warm upper air down to the surface. This prevents the ground from cooling <\/strong>like it normally would.<\/p>\n During the day, it’s the reverse.<\/p>\n The physical structures block and reflect some of the incoming solar radiation. But the blades continue to mix the air<\/strong>.<\/p>\n This creates a localized canopy effect, shielding the ground from daytime heat at its peak.<\/p>\n This temperature swapping is not an environmental disaster<\/strong>. But it is definitely a fascinating look at the footprint of human engineering<\/a>.<\/p>\n When we harvest natural forces on such a major scale, we automatically change the environment.<\/p>\n Is clean energy infrastructure really capable of permanently altering the climates of the landscapes we choose<\/a>? And are we prepared for the consequences<\/strong>?<\/p>\n","protected":false},"excerpt":{"rendered":" There are thousands of turbines in the California desert.
