CORRELATION COEFFICIENT(CC) Note at 07z CC values remain high indicating primarily snow aloft. Two hours later at 09z, ring of lower CC values indicate mixed phase precip with higher CC values again closer to the radar indicating all rain near the surface.
CORRELATION COEFFICIENT(CC) A radar signature commonly referred as “Tornado Debris Signature” (TDS) can be identified with dual-pol radar. Hook echo region of supercell can sometimes be characterized by area of enhanced reflectivity with low ZDR values and low CC values.
