Craig, as I recall from back issues of _Aviation Week_, RF-based radar
simply does not have the resolution to reliably detect CAT.  Air movement
is detected by some radars (such as the WSR-88D in clear air mode) due to
the radar seeing bugs and other stuff in the air being wafted about.
Obviously, you don't have much debris in the air at 40KAGL.  There has
been some progress made in using laser radar (LIDAR) for CAT detection,
