Some photos taken by Garfla of yesterday's mockery of nature:

Keep in mind that regular contrails do not create any radar signature. Nontheless:

Pointing to "birdie feet" on their scopes, the radar technicians showed Dickie particles appearing "as concentrations of dots" in the radar-tracked plumes."

Seeking to confirm or deny this phenomena I checked the NWS short base reflectivity returns at the time of the activity. There were no naturally ocurring cloud formations during this time period...

This certainly appears to be the same anomalous 'concentration of dots' that were reported by radar operators in Canada during CT activity.

The NASA contrail forecast showed negative for contrail formation, of course. This is at the recommended 225 mb level, but the forecast showed negative for any mb level in this area.

So, what we have here is a conflagration of anomlies stacked on top of each other:

1. Dozens upon dozens of persistant, dripping aerosol trails that bear aboslutely no similarity to normal contrails.

2. Said trails occuring under conditions that make even garden-variety contrail formation impossible.

3. Weather radar returning a signature "concentration of dots" that has been reported by operators in Canada during aerosol operations. This signature does not match a 'ground clutter' return in scope, configuration, or from what I can tell, intensity.

1. Ground clutter typically appears as a disk-shaped pattern on radar, as evidenced by the following examples.

Furthermore, the National Weather Servive radar processors filter out ground clutter based upon their lack of movement and Doppler velocity (which is zero). While I doubt that any filtering system is 100% reliable, it should be noted that even commercial radar manufacturers promote 'clutter-free' radar sytems:

I'm not sure if the the following url is archived or will update in real time, but I wanted folks to see the loop in action. Ground clutter is, of course, stationary... meterologists will look at the loop to determine if the return is stationary ground clutter or something airborne.
