What does DWR mean or stand for ?
DWR is a type of radar that is used exclusively for the detection of rain,snow hail or other weather phenomena that might be of any significance to an area.
DWR uses electromagnetic waves that are transmitted and received over a wide area of approximately between 50 to 100 miles.Very similar in its operation to SONAR,these radio-waves are received back when they interfere with other solid obstructions.
How DWR is different from traditional weather radar?Doppler weather radar not only gives a visual image of changing weather patterns,storms,hurricanes etc, but it can give a good idea of the direction,speed and intensity which can be very informative.
