Huo Shaoyun's stick figure

1, stick figure is the most typical and prominent main feature of objective image extracted through eye recognition, mental memory, handwriting and other activities. It shows generality, identifiability and schematic in a flat, stylized form and concise brushwork.

2, stick figure, refers to simplify the complex image, physical structure is the most basic element of painting, all kinds of objects have their own unique composition factors, structure and proportional relationship, plane stick figure, showing a relatively simple two-dimensional plane structure.

First of all, briefly introduce the flame cloud.

1, flaming clouds are also called morning glow and sunset glow, which means that when the sun just comes out or when the sun is about to set in the evening, the clouds on the horizon are often red like fire, so they are called flaming clouds.

2. Flame clouds are red clouds that appear at sunrise or sunset. Sunset clouds belong to the category of low clouds, which is one of the phenomena of atmospheric change. It often appears in summer, especially around sunset after a thunderstorm, in the west of the sky. Due to the strong evaporation on the ground and the great action of updraft in the atmosphere, the shape of fire clouds is ever-changing. The color of flame clouds is generally red, and the appearance of flame clouds indicates that the period of warm weather, abundant rainfall, lush biological growth and prosperity is coming. Sometimes it seems to indicate that an earthquake will happen somewhere.

Second, the causes of glow clouds

1. We already know that sunlight is a mixture of red, orange, yellow, green, cyan, blue and purple. The wavelengths of these colors of light are different. The red light wave is the longest, followed by the orange light wave, and the purple light wave is the shortest. Molecules in the air and countless tiny dust and water droplets floating in the air can disperse the colors of the sun, which is called scattering. The shorter the wavelength of light waves in the sun, the easier it is to scatter light such as purple and blue. The longer the wavelength, such as red and orange light, the less likely it is to scatter. In the morning or evening, the sunlight is oblique, and its distance through the air layer is relatively long, so the scattering is greatly weakened. The most attenuation is violet light, and the least attenuation is red light or orange light.

2. These weakened colored sunlight shines on the sky and clouds, forming bright and dazzling rosy clouds. When there are no clouds in the sky, there are few raindrops hanging in the air; At noon, the air layer is very thin, and almost all the red, orange, yellow and green light in the sunlight pass through, only blue, blue and purple light are blocked, and among these lights, blue light reflects the most, so the whole sky is dyed blue. [ 1]? When the sun rises in the east in the morning, or when the sun sets in the evening, the sun reaches the ground and passes through a thicker air layer than when the sun is at the top at noon. The yellow, green, cyan, blue and purple rays in the sun are exhausted after walking in the air layer not far away, and cannot pass through the air layer. Only red and orange light can pass through the air layer and dye the sky red.
