    One explanation for what is seen on the radar capture is beam interference.
    This occurs when there is radiation at a frequency near to the frequency
    of the radar beam. The most common situation where this occurs is when
    two beams from two identical radar platforms align. This pattern is commonly
    seen amongst the WSR-88D weather radars used by the NWS in the U.S.
    If one were to look at the radar towards the southwest from the location of
    'XSM' and at the same time as the capture image. one should see a similar
    pattern, but with a direction towards the northeast from the location of the
    radar site.
