Altocumulus
help to indicate convection, or rising heat, in the atmosphere. As warm air rises into the atmosphere, it cools and condenses water droplets in the area, which in turn form the cloud structures that we view from Earth's surface.
Cirrostratus
usually white and predict fair to pleasant weather. ... Cirrostratus clouds are thin, sheetlike high clouds that often cover the entire sky.
Stratocumulus
these clouds are often seen at either the front or tail end of worse weather, so they may indicate storms to come, in the form of thunderheads or gusty winds.
