A little understanding of the physics of cloud formation underscores the complexity of the atmosphere and sheds light on why predicting weather for more than a few days is such a challenge.

Six types of clouds you can see and how they can help you understand the weather.

1) Cumulus clouds - On a sunny day, rays warm the earth, which heats the air located directly above it. The heated air rises upward due to convection and forms cumulus clouds. These “good weather” clouds are like cotton wool. If you look at the sky filled with cumulus clouds, you can see that they have a flat bottom, located at the same level for all clouds. At this altitude, air rising from ground level cools down to the dew point. It usually doesn't rain from cumulus clouds, which means the weather will be good.

2) Cumulonimbus clouds.

Small cumulus clouds do not rain, but if they grow and grow in height, it is a sign that heavy rain is coming soon. This often happens in summer when morning cumulus clouds turn into cumulonimbus during the day. Cumulonimbus clouds often have a flat top. Air convection occurs inside such a cloud, and it gradually cools until it reaches the temperature of the surrounding atmosphere. At this moment, it loses its buoyancy and can no longer rise higher. Instead, it spreads out to the sides, forming the characteristic anvil shape.

3) Cirrus clouds form in very high layers of the atmosphere. They are smoky because they are composed entirely of ice crystals falling in the atmosphere. When cirrus clouds are carried by winds moving at different speeds, they take on a characteristic curved shape. And only at very high altitudes or at high latitudes, cirrus clouds give out rain that reaches the ground.

4) Stratus Clouds - A low-lying, continuous cloud sheet that covers the sky. Stratus clouds are formed by slowly rising air or gentle winds that cover the cold land or sea surface with moist air. Stratus clouds are thin, therefore, despite the gloomy picture, it is unlikely to rain from them, a little drizzle at most. Stratus clouds are identical to fog, so if you've ever walked in a mountainous area on a foggy day, you've been inside a cloud.

5) Lenticular clouds. Smooth and lenticular lenticular clouds form when air is blown up and over a mountain range, and as it travels over a mountain, the air descends to its previous level. At this time, it heats up and the cloud evaporates. But it can slip further, as a result of which the air rises again and forms another lenticular cloud. This can result in a chain of clouds extending far beyond the mountain range. The interaction of wind with mountains and other surface features is one of the many details that must be taken into account in computer simulations to obtain accurate weather predictions.

6) Kelvin - Helmholtz like a breaking ocean wave. When air masses at different heights move horizontally at different speeds, their state becomes unstable. The boundary between the air masses begins to ripple and form large waves, such clouds are quite rare.

Here, as always, is the MJ prompt.

The images are the result of refinement with the help of weighting "::2 and ::3". The chaos parameter c30 in combination with s1000 makes for a certain self-willedness of the AI.
