1：Sarah Ineson of Britain’s Meteorological Office and her colleagues compared the way that the Met Office’s new and putatively improved climate model dealt with winters at times of high UV and at times of low UV, using data on the amount of ultraviolet the sun gives off that were collected by a satellite called SORCE.

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，对冬季高紫外线和低紫外线的数据进行处理，这些数据是由一颗名叫SORCE的卫星收集太阳散发的紫外线量获得的。
2：Why had this solar effect not been seen before? To some extent it had. Earlier modelling of a period of prolonged low solar activity in the 17th and 18th centuries showed similar patterns. That models of today’s climate had not was, in part, because they used much lower estimates of the amount of UV variation over the solar cycle than those derived from the SORCE data, the most precise to be taken from a satellite looking at the sun. It may just be that working with more realistic data made the model work better.
为什么我们之前没有看出这种日光影响呢？某种程度上，我们是没看到过。更早以前，对17、18世纪时太阳活动持续不活跃时期所做的早期模型也体现了类似的模式。但如今的气候模型却体现出来。部分原因是因为采用了太阳周期内紫外线变化量的估计，而这些估计比SORCE的数据要低的多。卫星观察太阳所得出的数据更为精准。那么用更为接近实际的数据做出模型或许更为可靠。

Why had this solar effect not been seen before? It（=solar effect ) had （not been seen ） to some extent 。我是这么理解的，要不然接着的意思相反了，也得不出，数据越精确，模型越可靠的结论……

把我的意见中”更早以前，“去掉，重复了。呵呵

The sun’s activity waxes and wanes on an 11-year cycle,
太阳阴晴圆缺的周期是11年
我认为改为：太阳活动周期是11年，较好，毕竟太阳不像月亮有月相的变化。。。

另外，学习了。。。

回复 ycitshayun 的帖子

我认为后面说到17、18世纪做的模型就是为了说明之前研究过日光活跃性，可能研究目的不是针对太阳活动与气候变化的关联。后面说卫星数据更准确也阐明了本文的观点，即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。其数据的准确性不是普通模型能相比的
