时差N小时 什么是太阳能龙卷风(上)(在线收听) |
Large, Earth bound tornadoes are pretty impressive weather events. 大型地球龙卷风的天气现象让人印象深刻。 Those dark, giant funnel clouds inspire much awe and fear. 那些黑色、巨大的漏斗云让人心生敬畏和恐惧。 But they’re nothing compared to so called solar tornadoes solar gases swirling in monstrous formations deep within the sun’s atmosphere, 但这无法跟太阳能龙卷风相提并论,太阳能龙卷风是在太阳大气层深处形成的巨型太阳气体漩涡, measuring the width of several Earths and spinning at up to 190,000 miles per hour. 其宽度相当于几个地球,其旋转速度高达每小时19万英里。 Scientists have known about solar tornadoes for some time. 对于太阳能龙卷风,科学家已经了解了一段时间。 But just recently they’ve captured a massive one on camera for the first time. 然而最近,他们首次用相机捕捉到一次大型太阳能龙卷风。 Unlike earthly tornadoes, which consist of powerful swirling winds, 与地球龙卷风不同,太阳能龙卷风并非由强大的旋风形成, solar tornadoes are magnetic events involving super heated gasses being sucked up from the sun towards its atmosphere. 而是太阳能大气层吸收超热气体所产生的一种磁力现象。 |
