Words describing a kind of nature

In places such as calm seas, rivers, lakes, snowfields, deserts or Gobi, phantoms such as tall buildings, city outlines, and trees may occasionally appear in the air or "underground", which are called mirages. This kind of illusion often appears on the sea in Penglai, Shandong, my country. The ancients attributed it to a mirage belonging to the dragon family, which breathed out its breath to form a towering city outline, hence its name.

Mirages can not only occur at sea and in deserts, but can also occasionally be seen on asphalt roads. Mirage is the result of refraction of light in air layers with different densities in the vertical direction. There are many types of mirage. According to the position of its appearance relative to the original object, it can be divided into superior mirage, inferior mirage and lateral mirage; according to its symmetrical relationship with the original object, it can be divided into positive mirage, lateral mirage and lateral mirage. And reverse mirage; according to color, it can be divided into chromatic mirage and achromatic mirage, etc.

Mirages have two characteristics: first, they appear repeatedly in the same place. For example, mirages often appear over Alaska in the United States; second, they appear at a certain time. For example, most mirages in Penglai, my country, appear on May or June every year. In July, mirages near Tsimlensk, Russia, tend to appear in spring, while mirages in Alaska, the United States, generally appear within 20 days after June 20. Mirages are closely related to geographical location, geophysical conditions, and meteorological characteristics of those places at a specific time. Abnormal distribution of temperature is the meteorological condition that causes most mirages.

Let’s take the formation of mirage as an example. In the summer, the sun is blazing in the desert, and the sand is scorched. Because the specific heat of the sand is small, the temperature rises very quickly. The temperature of the lower air near the sand rises very high, while the temperature of the upper air remains very low, thus forming a temperature pattern. Abnormal distribution. Due to thermal expansion and contraction, the density of hot air in the lower layer close to the sand is small and the density of cold air in the upper layer is high. In this way, the refractive index of the air is small in the lower layer and large in the upper layer. When the light reflected from a taller object in the distance is continuously refracted from the denser air in the upper layer into the sparser air in the lower layer, its incident angle gradually increases, and total reflection occurs when it increases to equal the critical angle. At this time, if a person walks backwards If you look at the reflected light, you will see a mirage.

Due to the dark color of the asphalt road surface, it has a strong absorption capacity under the scorching sunlight in summer. It will also form a distribution pattern above the road surface where the air in the upper layer is cold and dense, while the air in the lower layer is hot and low density. Therefore, mirage will also be formed. .

The "mirage" that occurs in the desert is the refraction of sunlight when it encounters air of different densities. In the desert, the sand and rocks are baked by the sun during the day, and the temperature on the surface of the sand layer rises rapidly. Due to the poor heat transfer performance of the air, when there is no wind, the vertical temperature difference over the desert is very significant. It is hot at the bottom and cold at the top. The air density in the upper layer is high and the air density in the lower layer is low. When sunlight passes from a high-density air layer into a low-density air layer, the speed of light changes. After the refraction of light, the oasis in the distance appears in front of people's eyes.
