1. 在我国，古人很早就对日晕和月晕现象进行了研究，古谚有日晕三更雨，月晕午时风，其意思是若出现日晕的话，夜半三更将有雨，若出现月晕，则次日中午会刮风。从现代气象上来说，日晕的出现预示着大气中的水汽增加，低气压的到来，也就是所谓的三更雨，即未来的几天内可能有雨水降临。

1. In our country, ancient people carried out research on halos around the sun and the moon as early as a long time ago. There is an old saying: "A solar halo at midnight indicates rain, and a lunar halo at noon indicates wind." This means that if a solar halo appears, there will be rain at midnight; if a lunar halo appears, it will be windy the next noon. From a modern meteorological perspective, the appearance of a solar halo indicates an increase in water vapor in the atmosphere and the approach of low pressure, which is known as the midnight rain, meaning that rain may fall in the next few days.

2. 月晕是一种自然界的光学现象。它是由于当太阳或月亮的光线透过高而薄的白云（卷云、卷层云或卷积云）时，受到冰晶折射而形成的彩色光圈，彩色排列顺序内紫外红。出现在太阳周围的光圈叫日晕，出现在月亮周围的光圈叫月晕。

2. The halo is an optical phenomenon in nature. It is formed by a colorful ring of light, with the colors arranged from violet to red, when the light of the sun or the moon passes through high and thin clouds (cirrus, cirrostratus, or cirrocumulus) and is refracted by ice crystals. The halo that appears around the sun is called a solar halo, and the halo that appears around the moon is called a lunar halo.

3. 日晕三更雨，月晕午时风。是句谚语，意思是：太阳有晕的时侯，晚上三更（半夜）就会有雨，月亮有晕的话，第二天正午（11-13点）就会刮风。

3. The sun halo brings rain at the third watch, the moon halo brings wind at noon. This is a proverb, meaning: When there is a halo around the sun, it will rain at the third watch (midnight), and when there is a halo around the moon, it will blow wind at noon (11-1 PM) the next day.

4. 日晕也叫圆虹 ，一种大气光学现象，是日光通过卷层云时，受到冰晶的折射或反射而形成的。当光线射入卷层云中的冰晶后，经过两次折射，分散成不同方向的各色光。有卷层云时，天空中会飘浮着无数冰晶，在太阳周围同一圈上的冰晶，都能将同一种颜色的光折射到人的眼睛里形成内红外紫的晕环,(实际并没有)天空中有冰晶组成的卷层云时，往往在太阳周围出现一个或两个以上以太阳为中心、内红外紫的彩色光环，有时还会出现很多彩色或白色的光点和光弧，这些光环、光点和光弧统称为冰晕。

4. The halo, also known as the circular rainbow, is an atmospheric optical phenomenon formed when sunlight passes through lenticular clouds and is refracted or reflected by ice crystals. When light enters the ice crystals within the lenticular clouds, it is refracted twice and dispersed into various colors of light in different directions. When there are lenticular clouds, countless ice crystals float in the sky. The ice crystals on the same circle around the sun can refract the same color of light into the eyes of people, forming an inner red, outer purple halo (although this is not actually the case). When there are lenticular clouds composed of ice crystals in the sky, often there will be one or more colorful halos centered around the sun, with inner red, outer purple colors. Sometimes, many colored or white light points and light arcs may also appear. These halos, light points, and light arcs are collectively referred to as ice halos.
