Short summary
The study reports formation of supercooled drizzle drops in response to repeating kilometer-wide updrafts and downdrafts within a mixed-phase, mountain-layer cloud containing very little ice despite cold cloud top temperatures (T ~ -30°C). The discrete, embedded hydrometeor growth layers and downwind transition to drizzle production at cloud top indicates the relative importance of kinematic mechanisms in determining the location of precipitation development in cloud.
