What weather does the cotton cloud portend?

Cotton clouds are also called light cumulus clouds, broken cumulus clouds and flocculent high cumulus clouds, which indicate good weather.

After the rain and snow, fluffy clouds often float in the clear sky, which is lazy and comfortable. They are the low clouds in the cloud family: light cumulus clouds and broken cumulus clouds, which are especially like a mass of cotton, also called "cotton clouds". The appearance of light cumulus clouds and broken cumulus clouds will not bring precipitation, which is particularly friendly and is called "good weather clouds".

The bottom of the light cumulus cloud is flat and horizontal, and its cloud body can be clearly seen. Due to the sinking of the airflow, its edge becomes clear and sharp. However, due to the mixing effect of turbulent entrainment, its edge has a little sawtooth and irregular shape.

The appearance of light cumulus generally indicates that the weather is fine and it will not rain or snow. Especially in the afternoon, the sky is still faint cumulus clouds, indicating that the air is relatively stable. Light cumulus, also known as clear cumulus, is a sign of sunny days.

Summary and brief comments:

Cotton cloud has obvious indication function for important weather processes. For example, weather processes such as long-term drought to rain or heavy rain are the release of energy stored in the atmosphere under certain conditions. This physical transformation process is first reflected in the instability of the upper and middle air layers, and also deeply reflected in the evolution of clouds.

The formation of cotton cloud is an early representation of this physical transformation process under certain conditions. The number and duration of flocculent cumulus clouds have different indicative meanings.

The large number, long duration, rapid change and different clouds reflect the strong influence system and strong weather process. The movement of air in the atmosphere is ever-changing, and the specific situation should be analyzed in detail.
