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.
美国航天局戈达德航天研究所的科学家在《地球物理研究杂志》上发表的研究报告说,人类工作中产生释放的化学物质,特别是汽车尾气等废气,是造成此种异常天气现象的原因。
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.
废气排放会影响大气的湿度,人们工作时,废气排放量会达到峰值。到周末,人们休息时,废气排放量就会下降。
The effect doesn't seem to be reproduced on the West Coast of America - so it may be limited to moister climates.
人类活动对天气产生的这种影响在美国西海岸并不适用,也许这种效应仅限于比较潮湿的气候。
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 also near its weekly maximum.'
研究者说:“这项研究第一次用统计数据证明了:夏季人类活动产生的废气排放量在一周的中段达到峰值时,龙卷风和冰雹等异常天气状况发生的概率也接近一周中的最高值。”
