What cloud is this? Is this a sign of what weather phenomenon is going to happen?

There are three kinds of clouds here. The upper clouds are light cumulus clouds and broken cumulus clouds. These two kinds of clouds go hand in hand and appear in clear weather (in this case, the blue background of the picture represents the blue sky). But if it's raining, the clouds in this shape belong to broken rain clouds.

There are also two kinds of striped clouds below. One is the wake cloud of fighter planes, which only appears when the weather is clear, and generally fades and expands gradually; Another case is that the striped clouds on cloudy days are stratocumulus clouds.
