Researchers at State University New York in Albany have found wind farms affect local temperature changes in certain areas of the U.S.
According to a new study, temperatures increased near four of the largest wind farms in Texas. The problem? The giant 1)propellers caused the air to circulate more. Warmer air from higher up in the atmosphere is pulled down to mix with the cooler ground temperatures.
The study was published in Nature Climate Change, and results show “...a significant warming trend of up to 0.72 degrees centigrade per decade, particularly at nighttime, over wind farms relative to nearby non-wind-farms regions.”
The Examiner quotes one of the researchers noting the limitations of the study. “The estimated warming trends only apply to the study region and…period, and thus should not be 2)interpolated into other regions, globally or over longer periods...”

一項新的研究顯示,得克薩斯州四個最大的風力發(fā)電場的周圍氣溫上升。這是什么原因造成的呢?巨大的風車葉片導(dǎo)致空氣流動更多,使大氣層中上層溫暖氣流下墜,與地面上較低溫度的空氣混在一起。
相關(guān)的研究報告刊登在《自然氣候變化》雜志,其結(jié)果表明:“風力發(fā)電場所處的地區(qū)與附近沒有風力發(fā)電場的地區(qū)相比,氣溫呈現(xiàn)一種上升的趨勢,每十年里氣溫上升幅度達0.72攝氏度,在晚間尤為突出。”
《考察者報》引用一位研究人員的話,指出了此項研究的局限性。“研究中預(yù)計的氣候轉(zhuǎn)暖的趨勢只適用于研究的地區(qū)與時期,僅此而已。因此不適用于其他地區(qū)、全球,或者更長的時期。”
