The Science Behind Altostratus Clouds

Altostratus clouds are mid-level clouds that are often seen as gray or darker white. These clouds usually cover most of the sky, but it still is kind of bright outside where you can still see the sun through the clouds. At some points, you can see a halo around the sun from these clouds.

Altostratus clouds typically form ahead of a warm or occluded front ahead of any precipitation. This cloud may sometimes produce rain itself. Now you know the science behind altostratus clouds.
