Everyone knows how the work week can take a toll on employees, but new research suggests the five-day slog may have even broader impacts--on climate.

    人們普遍了解工作日是如何影響上班族的，然而最新研究表明這五天的勞作對(duì)氣候的影響更加顯著。

    After examining more than 40 years of temperature data taken from roughly 10,000 surface stations, researchers from the National Oceanic and Atmospheric Administration and from the University of Reading in the U.K. found that temperature differences between day and night appear to follow distinct five-days-on, two-days-off patterns.

    英國(guó)國(guó)家海洋及大氣管理局和英國(guó)國(guó)立瑞丁大學(xué)的研究員分析了約一萬(wàn)個(gè)地面氣象站40多年來(lái)采集的氣溫?cái)?shù)據(jù)。他們發(fā)現(xiàn)晝夜溫差出現(xiàn)明顯的五天大兩天小的變化規(guī)律。

    The scientists checked the data for all possible natural influences such as the lunar cycle as well as random variations and found neither to be at play. The only factor that could be causing the fluctuations was the Monday-through-Friday grind, they concluded in a recently published report in the Proceedings of the National Academy of Sciences.

    科學(xué)家們檢查了所有可能造成這種變化的自然因素，例如月亮運(yùn)行周期和隨機(jī)的變化，結(jié)果發(fā)現(xiàn)二者都不起作用。他們?cè)谧罱�召開的全國(guó)科學(xué)院研討會(huì)上發(fā)表的報(bào)告中總結(jié)說(shuō)：唯一可能解釋這種溫差變化的就是人們從周一到周五的辛苦勞作。

    "There is nothing in nature that should cause these data to be different," said Piers M de F. Forster, a meteorologist based at the University of Reading, England, who co-authored the study with NOAA's Susan Solomon. "So whatever the cause we find has to be something that we're changing, ourselves."

    英國(guó)國(guó)立瑞丁大學(xué)的氣象學(xué)家皮爾斯•福雷斯特和國(guó)家海洋及大氣管理局的蘇姍•所羅門合作主持了這項(xiàng)研究。福雷斯特說(shuō)：“自然界中沒有什么能夠造成這些數(shù)據(jù)差異，所以不管原因是什么，它一定與我們自己正在改變的某種東西有關(guān)。”

    The meteorologists propose the differences in average temperatures between Saturdays as opposed to Thursdays, for example, may stem from workweek-induced pollution. Forster explains that during the workweek more people commute and more factories are in operation. Both contribute to the amount of particle pollution in the air.

    氣象學(xué)家們提出平均氣溫的差異可能是工作日中產(chǎn)生的污染造成的，例如周六和周四相比，平均氣溫就有一定的差異。福雷斯特解釋說(shuō)在五天工作日中，乘車上下班的人多，進(jìn)行生產(chǎn)的工廠也多，這都會(huì)增加空氣中的微粒含量，對(duì)大氣造成污染。

    Particles can influence cloud cover, but the kind of particles released into the atmosphere can lead to different changes, says Forster.

    微粒會(huì)影響云量，但是釋放到大氣中的不同顆粒會(huì)造成不同的變化，福雷斯特說(shuō)。

    Lighter particles provide a surface for cloud droplets to form. This leads to an increase in cloud cover, which, in turn, can lead to an increase in temperature since clouds have an insulating effect.

    較輕的微粒能夠提供云滴形成所需要的界面，這樣會(huì)增加云量，進(jìn)而導(dǎo)致氣溫的升高，因?yàn)樵朴斜�溫的作用�?
