AB: High spatial and temporal observations from a profiling cloud radar reveal sharp shear/density boundaries in the interior of Florida convective anvils. These discontinuities where seen at all multiple levels within the anvil, lasting for periods of 15 minutes up to several hours. These discontinuity layers effectively divided the anvil into layers with distinct characteristics, and suggest different source regions for the different layers. The most prominent of these discontinuities lasted for approximately 4 hours. At times this layer exhibited clear Kelvin-Helmholtz instability breaking waves.
