Midwest and DC Rocked by Derecho
Many people now know a term that only meteorologists and weather geeks usually know. Derecho. (It’s pronounced “da ray show”) A derecho is a fast-moving cluster of thunderstorms that produces very high winds, and moves very rapidly. They like to form in June and July, and they favor certain areas of the country like the Midwest, Great Lakes, and Mid-Atlantic/Pennsylvania. They also tend to form on the north side of …

Hydro ID off of ARMOR
27 May, 2005 I showed some of our first echo id data on air at 10pm Thursday.(See the last blog) Using ARMOR and it’s dual polarimetric capability, a computer program can be run to analyze the radar echoes using different variables like differential reflectivity and specific differential phase etc. (I have a link at the end that will explain these) This program can then estimate whether the echo is rain..sleet …
