但这项研究却让人们从气候变化中学到了其他两点:影响因子的数据有时候很难得到;气候的电脑模型能够模拟出现在的气候状况,让人印象深刻。
The sun s activity waxes and wanes on an 11-year cycle, and over this cycle the amount ofultraviolet light the sun emits changes a lot more than does the total amount of energy.
太阳的活动周期是11年,在此周期内太阳散发出的紫外线总量的变化比太阳能总量的变化要大的多。
The stratosphere, the part of the Earth s atmosphere which does most to absorb UV, mightthus be expected to be particularly sensitive to the cycle.
吸收大部分紫外线的平流层?地球大气圈的一部分,在此周期内可能会变得异常敏感。
In a paper just published in Nature Geoscience, Sarah Ineson of Britain s Meteorological Officeand her colleagues compared the way that the Met Office s new and putatively improvedclimate model dealt with winters at times of high UV and at times of low UV, using data onthe amount of ultraviolet the sun gives off that were collected by a satellite called SORCE.
刚刚在《自然-地球科学》杂志上发表的一篇论文中,英国气象办公室的沙哈.伊内森和她的同事用该气象办公室公认的新型气候改进模型,对其在冬天纪录的高紫外线和低紫外线数据进行比较,这些数据是由一架名叫SORCE的卫星收集太阳散发的紫外线量获得的。
