Doppler measurements and applications


- 4.1 General background

  • How a Doppler radar works, S-band, C-band
  • Folding
  • Non-meteorological echoes


- 4.2 PPI displays of raw Doppler data of radial wind

The aim of this chapter is for the forecaster to be able to recognize mesoscale vortices and convergence and recognize wind towards or away from the radar.


- 4.3 Wind profiles

The aim of this chapter is for the forecaster to be able to identify and follow the warm and cold advection, layers of vertical shear, fronts, low level jets.

  • risk of folding even here (how to recognize)


- 4.4. Shear products and warnings

The aim of this chapter is for the forecaster to be able to be aware when and where the automatic warnings (of e.g. azimuthal shear) do not work

  • Data fusion (compare to dBZ)
  • Geometry (near and far away from the radar...)
