The Doppler radar weather map that shows the most severe rain storms would typically display dBZ values in the highest range, usually above 50 dBZ. These higher dBZ values indicate intense precipitation, often associated with heavy rain, thunderstorms, and potentially severe weather events such as flash floods or hail.
On a radar map, colors representing dBZ values may vary, with dark reds or purples often indicating the most extreme levels of precipitation (e.g., values greater than 60 dBZ). Therefore, if you want to identify the radar map with the most severe rain storms, look for the areas highlighted with the highest color ratings on the scale, indicative of intense rainfall rates.
