What you are looking at is a map of Florida as a hurricane approaching from the Gulf of Mexico hits the west coast. If it wasn't for maps like this people would have no idea of the approaching storm. These maps are used by all weather forecasters to show what the human eye can not see and to predict potentially disastrous weather in the future. Doppler radars come from satellite images and usually show a certain time frame so you can see the direction of a storm front. Doppler radars are also very important for aviation so that pilots can see what kind of skies they are heading into.
Doppler radars work by sending microwave signals through space and waiting for a returning frequency to analyze the depth of the weather. It is a very important tool and these maps will continue to save lives and help people for many years to come.
