木星“大红斑”的实验室模拟

Laboratory simulation of Jupiter's great red spot

在我们建立的旋转浅水实验系统上进行了可重复的系列模拟实验 ,成功地观测到大尺度持续存在的涡旋的产生、漂移与演化 .在一定条件下 ,呈现出一个自持的、长寿命的、沿与整体旋转方向相反方向漂移的反气旋孤立波涡旋 ( Rossby soliton) ,这就是木星“大红斑”的实验室模型 .

A series of repeatable simulation tests were carried out on the experimental system of rotating shallow water.The generation ,drift and evolution of persistent vortices on the large scale were observed successfully.Under the certain condition ,an anticyclonic solitary vortex was produced,which was the only one along the whole perimeter of the system,stationary drifting during an infinitely long time,counter directed to the general rotation of the system.This structure is interpreted as the Rossby solitary vortex and as a laboratory model of Jupiter's Great Red Spot.
