Strobes
Strobes are spurious radar data caused primarily by defractive bending of the beam back down to the ground. This often happens in areas where cool air interacts with prevailing warm air, such as along coastlines and over oceans or other large bodies of water. The following image from MLB Melbourne FL shows heavy strobe contamination throughout much of the radar scan. At first glance the reflectivity appears blocky and intense, similar to precipitation. However, notice the linearity of some areas of reflectivity as well as widely scattered occurrences of more intense reflectivities. Precipitation, even scattered precipitation, often appears more continuous and connected. These blocky and linear features are characteristics of strobe contamination.
