THEWEATHERMOGIL:: Fair weather funnel for Naples, FL
Typically seen in high wind shear environments, “fair weather” funnels are awesome things to encounter. They usually form through vortex stretching, are always short-lived, and shouldn’t ever touch the ground. They also form during “benign” weather scenarios.
Yesterday, I caught one, totally by accident (as is usually the case). I was observing the southwest Florida sea breeze (Fig. 1), which is marked by a distinct cloud-no-cloud boundary. The cloud-free zone is closest to the water (image was taken facing southwest).
Then, I glanced up as the boundary oscillated overhead and saw a laminar tube-like shape within the overall puffy to ragged clouds. That visible difference in cloud shape is what caused me to think about something unusual. I quickly grabbed several pictures (Fig. 2 and Fig. 3, shown here) and then, as quickly as it appeared, it was gone.
If you haven’t seen a “fair weather” funnel yet, then keep an eye to the sky. Those funnels are out there!
