One type of these objects forms at the crest of a lee wave after undergoing orographic lift.
One type of these objects forms at the crest of a lee wave after undergoing orographic lift. That type has multiple layers which together form a mushroom shape and is termed "lenticular." One emanation from these objects is called virga, which never reaches its normal destination. The CLAW hypothesis posits that their formation can be triggered by sulfate aerosols, the "seeds" or "nuclei" around which they condense below the dew point. Electric potential differences between their lower regions and upper anvil-shaped portion result in lightning. For 10 points, name these masses of water and ice suspended in the atmosphere, such as stratus and cirrus.
