An accessory cloud is a cloud which is dependent on a larger cloud system for its development and continuance. It is often an appendage but also can be adjacent to the parent cloud system.^[1]

The arcus clouds roll clouds and shelf clouds, wall clouds, and scud are examples of low level accessory clouds whilst the anvil, pileus, overshooting top, and mammatus are examples of high level accessory clouds. The condensation funnel of funnel clouds and tornadoes are also accessory clouds.
