What is a limitation of weather radar according to the context provided?

Weather radar is designed to detect various atmospheric phenomena, such as precipitation, but it has certain limitations when it comes to identifying specific types of weather events. In this case, the correct choice indicates that weather radar does not reliably detect hail. This is primarily because hail can often be mixed with other forms of precipitation, making it challenging for radar to isolate and identify it accurately.

While weather radar is capable of tracking precipitation intensity and movement, it might struggle with differentiating between small ice particles like hail and other forms of precipitation such as rain or snow. The size and composition of hail can result in radar signals being less reliable, which can affect the overall accuracy of hail detection.

Understanding this limitation helps meteorologists to incorporate additional tools and methods alongside radar, such as satellite data and ground reports, to get a more comprehensive picture of severe weather conditions, including hail.
