See a mistake? Contact us. Question: On some NEXRAD images, I sometimes see a negative value for dBZ (decibel related to Z) for the reflectivity. How can these values be negative? Answer: Of all of ...

Two weeks ago, I talked about an introduction to radar and how it works on a basic level. This time, we are looking into radar reflectivity specifically, the most popular product of weather radar.

Meteorologists are often tasked with making predictions, but understanding the present can be equally important and similarly daunting. When faced with tornadoes, which can develop, intensify and ...
