Reflectivity Image

The green ring indicates the Radius of Maximum Winds (RMW) as determined by the peak positive and negative isodops shown by the small white circles.

Because the rotation angle of the isodops exceeds the tolerance threshold, a secondary calculation produced the RMW shown here.

The red ring indicates the Radius of Maximum Reflectivity as modeled by the REFLEYE algorithm.

Range rings = 50 km.
