PDF-Operational Use of Spectrum Width from NWS Doppler Radar Data Spectrum Width One of the

In a radar bin it provides a measure of the variability of the mean radial velocity estimates movement due to wind shear turbulence andor the quality of the velocity samples The proper use of Spectrum Width can help the severe thunderstorm and torna. The velocity of different frequencies can be different due to intrinsic properties of the medium or due to dispersive nature of the bound structure like the optical fiber Due to dispersion when the optical pulses travel along the fiber they broaden .
