Cloud radar images show a scale of dBZ between +40 and -40. What are dBZ and what is their significance? Thank you.
It is a weather of equivalent reflectivity (Z) of a radar signal reflected off a cloud. dBZ stands for decibels of Z. The reference level for Z is 1 micrometer 3. It is related to the number of drops per unit volume and the drop diameter.
