A Good Rule of Thumb to interpreting weather radar is: a. The lighter the coloring, the lighter the winds. b. The darker the coloring, the higher the winds. c. The higher the reflectivity value, the lighter the precipitation rate. d. The higher the reflectivity value, the heavier the precipitation rate. 4.

Pilots can identify whether the intensity of precipitation is getting stronger or weaker by watching the color variations of the corresponding radar echoes. The trend of precipitation (weakening or developing) can be identified by noting: a. the expansion or contraction of the total coverage area in time. b. the colorized wind gradient. c. the changing color of the PRECIP box located on the right hand legend. d. the changing color of the radar rings. 5.

A common radar interpretation error is Beam Attenuation. This is caused by: a. the radar beam overshooting clouds or intense precipitation close to the ground. b. storms closest to the radar sight reflecting or absorbing the available beam energy. c. precipitation occurring aloft but not reaching the ground. d. a strong temperature inversion low in the atmosphere. 6.
