Nettet7. jul. 2024 · Rime ice often happens in areas of dense fog, like we have seen the past couple of nights. It is when supercooled water drops (in liquid form) in the air come in contact with a surface below freezing. Those liquid water droplets then freeze on contact. Hoar frost is similar to dew and happens on cold and clear nights. Nettet微信公众号星期一诗社介绍：一个纯诗歌类公众号，如果不能令你惊鸿一瞥，想错过，就错过吧。；艾米莉·狄金森诗115首
