Station Model - Cloud Types

Cloud Types

Above or below the shape indicating sky cover can lie a symbol indicating cloud type. One cloud type is depicted for each of three possible cloud layers, if known. The top two cloud layer types are depicted above the sky cover circle in the station model, while the lowest cloud type is indicated below the sky cover circle. The symbols used for clouds emulate the cloud shape. Cirrus is indicated by a couple hooks, cumulus are indicated by a mound shape, with cumulonimbus indicated with an upside down trapezoid on top of the cumulus symbol to indicate its anvil. Since the station model has limited room, when there is more than one cloud type present per level, the cloud type with the highest priority is included. Knowing the cloud type at various locations can help determine whether or not a weather front has passed by a particular location. A low deck of stratus could indicate a station is still north of a warm front, while thunderstorms can indicate the approach of a squall line or cold front.
