Question 3. What happens to the reflectivity feature between 2:30 and 4:30 p.m.?
What else happens in the radar data between 2:30 and 4:30 p.m.?
Answer. There are two different modes that the radar can be in for base reflectivity: Clear Air and Precip.
Clear Air mode picks up lower reflectivity values better while Precip mode give a better picture of storm
structure. The dryline does not disappear, but the mode of the radar changes and cannot detect as well as
before the switch.
