What are the reasons why clouds in the sky show different colors?

The reasons why clouds in the sky show different colors are the change of solar altitude angle, gases and particles in the atmosphere, types and heights of clouds and weather conditions.

1, the change of solar altitude angle: when the sun rises or sets, the distance of sunlight passing through the atmosphere becomes longer, which will scatter different colors in the light to different degrees, resulting in different colors in the clouds.

2. Gases and particles in the atmosphere: Gases and particles in the atmosphere will affect the propagation of light, causing different colors in the light to be scattered to different degrees, thus causing different colors in the clouds.

3. Types and heights of clouds: Different types and heights of clouds will reflect and scatter different colors of light, thus presenting different colors.

4. Weather conditions: Different weather conditions will lead to different colors of clouds. For example, clouds in rainy days will be dark, and clouds in sunny days will be bright.

Explanation of cloud discoloration;

This is a natural phenomenon. A cloud is a collection of many tiny water droplets or ice crystals. When sunlight hits the earth's surface, it will provide heat to the earth's surface, so that water molecules can gain energy, escape from liquids or solids and become gases. After water vapor enters the atmosphere, it will change at different heights and temperatures as the air rises or falls.

When water vapor rises to a certain height, it will encounter colder air. At this time, water vapor will lose energy, change back to liquid or solid, form water droplets or ice crystals, and produce different colors due to the refraction and diffraction of solar light.

The color change law of clouds

1, the influence of sunlight: sunlight is composed of light of various colors, and water droplets and ice crystals in the cloud scatter light of various colors. Clouds may appear orange or red when the lighting conditions are suitable.

2. Influence of cloud thickness: The thickness of the cloud will directly affect the color of the cloud. Thick clouds will weaken the light at the bottom and make the clouds appear dark gray or black. On the contrary, thinner clouds are easy for light to penetrate and make them appear brighter.

3. Influence of climatic conditions: Temperature, humidity, air pressure and other climatic conditions will affect the formation process of clouds, thus affecting the shape of clouds. Strong winds will break, deform or lengthen clouds, forming clouds such as cirrostratus and cumulonimbus clouds. In the case of low wind speed, clouds may maintain a stable shape, such as stratiform clouds or cumulus clouds.
