Schematic depicts a vertical cross-section of a mesoscale convective system (MSC) that is organized as a squall line with trailing stratiform precipitation. An office is asked to determine the height/temperature of the cell forming along the leading edge of the squall line. The answer is the –10°C to –20°C level based on earlier discussions about graupel formation. The same office is asked to determine the height/temperature of the enhanced echo in the stratiform region. This information has not been covered but most offices are able to provide the correct answer: the 0°C level causes melting, aggregation and enhanced radar return. This feature is called a stratiform radar brightband.
