Interpretation of Doppler Velocities

• In addition to the radar reflectivity field, radars collect information about the wind
• Doppler radars measure the radial velocity
• the radial velocity is defined as the component of the wind in the direction parallel to the radar beam orientation
•  
• Now, in this image, where is the hook echo and how can you see the low-level rotation in the velocity data?
• Practice your skills at interpreting Doppler radial velocities:
  • | reflectivity loop |  radial velocity loop |

QUESTION FOR THOUGHT:

Draw an idealized pattern radial velocity isopleths that represents a microburst signature at low levels.
