The effect is related to the hum of human activity - and thus chemical releases - and peaks mid-week. 工作日出現(xiàn)極端天氣的概率比周末時(shí)段高出20%。這與人類的生產(chǎn)活動(dòng)緊密相關(guān)，人類活動(dòng)排放的化學(xué)物質(zhì)會(huì)在一周中段達(dá)到峰值。 The study analysed weather along the East Coast of America during summer, and found that there is a blip in the number of tornadoes and hailstorms mid-week - and it cant be explained away by isolated events, or by improvements in weather reporting. 研究人員分析了美國東海岸夏季的氣候，發(fā)現(xiàn)龍卷風(fēng)和冰雹多發(fā)生在一周中間時(shí)段。這一現(xiàn)象不是孤立事件，也不是天氣預(yù)報(bào)出現(xiàn)了失誤。 The study, by Nasa Goddard scientists and published in the Journal of Geophysical Research says that the peak in storms is caused by chemicals released by humans as they work, particularly aerosols such as exhaust smoke. 美國航天局戈達(dá)德航天研究所的科學(xué)家在地球物理研究雜志上發(fā)表的研究報(bào)告說，人類工作中產(chǎn)生釋放的化學(xué)物質(zhì)，特別是汽車尾氣等廢氣，是造成此種異常天氣現(xiàn)象的原因。 Aerosol release has known effects on moisture in the air - and releases tend to peak when people are at work. When people relax at weekends, releases drop. 廢氣排放會(huì)影響大氣的濕度，人們工作時(shí)，廢氣排放量會(huì)達(dá)到峰值。到周末，人們休息時(shí)，廢氣排放量就會(huì)下降。 The effect doesnt seem to be reproduced on the West Coast of America - so it may be limited to moister climates. 人類活動(dòng)對天氣產(chǎn)生的這種影響在美國西海岸并不適用，也許這種效應(yīng)僅限于比較潮濕的氣候。 The researchers said, This study shows for the first time statistical evidence that when man-made aerosol releases during summer time are at their weekly mid-week peak, tornado and hailstorm activity there is al
