Questions

1. If the 0^o azimuth on the radar screen is north, what direction is 90^o?
   
   
   90^o?________ 180^o?________ 270^o?________
   
   
   
2. Place a ruler on the part of the zero velocity line that runs through the radar station.
   The wind blows perpendicular to this line.
   What direction is the wind coming from? ________________________
   
   
3. What two colors represent the fastest air velocities, and what are their speeds in meters
   per second?
   
   _________________________________________________________________________
   
   
4. Change the wind velocity from 9 meters per second (m/s) to miles per hour (mph). Use
   the unit analysis technique set up below.
   
   
   
   
   
   
5. What is the diameter of the outer ring of the radar screen in miles? _______________________
   
   (Hint: Range rings measure distance from the radar. Therefore, the diameter of the
   outer range ring is 40 km or two times the 20 km radius.)
