vortices

Polar vortices are found on Earth, Jupiter , Mars and Venus, and are colder than their surroundings.

人们在地球 、 木星 、 火星和金星上都发现了极地涡流,它们比周围的气候环境更冷.

These vortices developed within 30 minutes or so of each other.

这些涡旋的产生彼此相隔半小时左右.

The vortices are caused by quantum-mechanical inference scatterers and are accentuated by evanescent states.

涡流出现是量子相干散射造成的,并与衰减模式的存在有重要关系.

Moving the perturbation location along the circumference gives an expected series of asymmetric vortices.
