Ask The Weatherman for September 9, 2013:
Question: What are some things that can be seen on the weather radar?
Answer: The radar is a highly sophisticated weather instrument that looks into the atmosphere and can give meteorologists a wide array of information including: when the next thunderstorm will start or finish; will the thunderstorm have strong winds; and how heavy will the rainfall be. Along with that we can also use the radar to determine if the thunderstorm is rotating so that we can issue tornado warnings along with severe thunderstorm warnings. This is just the thunderstorm aspect of the radar. We can also use it for winter weather.
