- In the presence of a strong,
inversion near the ground, the radar beam may be refracted
- Recall from Physical Met that
electromagnetic and sound waves may be refracted
in the atmosphere due to density variations (Snells Law)
- If a strong low-level inversion
exists, the radar beam may be refracted such that
it strikes the ground some distance from the
- The resultant echo is from the
ground (ground clutter) and is called anomalous
- Here is
- What time of the day would you
more likely expect to see anomalous propagation?
