英語(yǔ)時(shí)差：風(fēng)電場(chǎng)影響氣溫？2

When turbine blades spin, they create turbulence similar to how a motorboat churns up the water in its wake. Consequently, cooler air from higher in the atmosphere is pushed down. Meanwhile, warmer air lower to the ground is drawn up, where it mixes with the cooler air. Location Matters Whether a wind farm has an overall cooling or warming effect depends where it is. In the Midwest and Great Plains, wind tends to blow more strongly at night. So wind farms there generate longer periods of slightly warmer temperatures. Wind farms near the coastline, where wind blows mostly during the day, may have the opposite effect and create overall cooler temperatures. Is This A Problem? So are these cooling and warming effects a problem? It depends who you ask. Inland farmers, at least, tend to like how wind farms keep things warm, warding off frost and extending the growing season later into the year.
