On weather radar, strong reflectivity above a weak echo region may indicate what?
Answer and explanation
Correct answer: A very strong updraft suspending precipitation particles aloft
A bounded weak-echo region occurs when a powerful updraft lifts and suspends water droplets, hail, and ice particles, leaving a relatively low-reflectivity area beneath or within stronger echoes. The surrounding high reflectivity represents concentrated hydrometeors. This radar structure is an important sign of a strong, potentially severe storm.
