In an RHI, Bragg scattering can be used to identify which atmospheric feature?

Bragg scattering is a phenomenon that occurs when radar waves interact with small, regularly spaced atmospheric scatterers, such as temperature profiles or interfaces within the atmosphere. In the context of radar meteorology, this type of scattering is particularly useful for identifying boundaries where there are abrupt changes in atmospheric properties, such as the top of the boundary layer.

When radar emits waves, these waves can be reflected back when they encounter interfaces where there are significant changes in either temperature or density of air. The top of the boundary layer is typically characterized by a thermal inversion, where warmer air overlays cooler air, causing a distinct change in the refractive index. This sharp transition allows for the clear detection of the boundary layer's top through Bragg scattering.

While the other options present interesting atmospheric features, they do not utilize Bragg scattering in the same way. For instance, while the presence of precipitation might generate reflections, it is typically identified through different scattering mechanisms based on raindrop size and density rather than Bragg scattering. Similarly, identifying the presence of a storm center involves more complex storm dynamics and structure than what Bragg scattering can directly provide. Lastly, temperature inversions do coincide with Bragg scattering, but they are not the primary feature that the scattering would highlight in
