WebbPolarization vectors near the singularity have anomalous properties, which depend on the type of singularity. The wave surface (also called the group velocity surface) is defined by the set of all group velocity vectors v. They can be parameterized by slowness vector p, vZv(p), by slowness direction n, vZv(n), or by ray direction N, vZv(N). Webb26 aug. 2016 · The observed slowness of the SV wave suggests that the source could be located in the same area of the P wave microseisms in the Atlantic Ocean. The simplest mechanism of the observed S wave excitation is the P -to- SV conversion on the sea bottom during multiple reflections within the ocean ( 7 ).
