Block 1 - Assignment 12
What is the beam width of WSR-88D?
0.95 degrees
What is the wavelength of the WSR-88D?
10 cm
What is the strongest radar reflectivity from the area circled at Point A?
50 dBZ
The amount of radar energy returned directly back to the radar after striking a target is called
backscattered energy
Under normal conditions (standard refraction), a radar beam tends to
bend downward
What type of condition occurs when the radar beam bends equal to or greater than the Earth's curvature?
ducting
How would air traffic control classify a radar echo that is less than 26 dbZ?
light
The decrease of the intensity of energy within the radar beam as the beam gets farther away from the antenna is known as
range attenuation
What type of condition occurs when the density of the atmosphere decreases with height at a less than normal rate and the radar beam bends more than normal?
superrefraction
The amount of precipitation attenuation is related to the wavelength of the radar.
true
