How do Three Body Scatterer Spikes orient in relation to the hail core?

Three Body Scatterer Spikes occur when there are scattering events from three distinct bodies: the raindrops or hailstone, the radar beam, and the earth's surface. These spikes are associated with the presence of large hydrometeors, often hail, which, due to their size and shape, significantly affect the radar return signals.

In relation to the hail core, the Three Body Scatterer Spikes point outward radially from the core. This orientation occurs because the large hailstones scatter the radar energy away from the core as they interact with both the incoming radar beam and the reflected signals from the ground. The geometry of the scattering process results in these spikes appearing as though they are emanating from the hail core itself and spreading outward.

Therefore, understanding how these spikes behave provides important insights into the reflectivity patterns in radar data, helping meteorologists assess hail presence and size. This outward orientation is crucial in interpreting radar data effectively, especially when analyzing severe weather systems where hail might be present.
