How to draw cloudy?

Draw the shape of a cloud. On the original basis, draw a straight line and a half arc beside it to perfect the shape of the second cloud. Then insert a cloud in the middle and paint it blue-gray. In this way, a cloudy stick figure is drawn.

Cloudy is a meteorological term. In the weather forecast, "cloudy" weather has a strict definition. Refers to a kind of weather that can be called "between sunny and cloudy". Be careful of ultraviolet rays in cloudy days. Ultraviolet ray is the general name of radiation with the wavelength from 10 nm to 400 nm in the electromagnetic spectrum, which can't be detected by human eyes, but too much ultraviolet ray may harm eyes.

In cloudy summer, people should not forget to protect their sensitive eyes, because some ultraviolet rays can still reach the surface through the clouds, and exposing their eyes to these ultraviolet rays for a long time is likely to cause some harm. The association also said that people who stay near the water for a long time should pay more attention to protecting their eyes because the water reflects light. If the eyes are damaged by too much ultraviolet rays, there will be symptoms such as redness, tears and eye muscle tension.
