decagon、atmospheric wave、jet stream、vertex 等词,并拆解一句长句。最后完整重播英文原文,帮助你检验自己是否听懂了“波形移动很慢”和“周围气流很快”这两个层次。decagon:十边形atmospheric wave:大气波,指大气中的波动结构,不是固体物体jet stream:喷流,狭长而快速移动的气流带vertex:顶点;复数 vertices 指多个顶点hemisphere:半球evolving:正在变化、逐渐形成的meandering:蜿蜒摆动的confined:被限制在一定范围内的vortex:涡旋The decagon could be a large-scale meandering wave trapped by the surrounding jet.The decagon could be a wave,意思是“这个十边形可能是一种波”。large-scale 表示大尺度,meandering 表示蜿蜒摆动,trapped by the surrounding jet 表示受到周围喷流的限制。science.nasa.gov
