Challenging Detection

As was the case with the Stecker tornado in Storm A, there is little precipitation wrapping around this tornado southwest of Anadarko. This results in too few inbound velocity gates for an algorithm detection, at least at the lowest tilt.  The strong shear at tilt 2 should have been detected, but was missed by the MDA.  At the third tilt, a dealiasing error corrupts the data. By this time, the radar beam is already up to near 5.3 km in the storm, and subsequent scans are too high to detect the low and mid-level mesocyclone. The detected mesocyclone is valid, but is not the one responsible for the tornado occurring during this particular volume scan.
