Local author, researcher and historian Bill Miesse will give a presentation about lenticular clouds entitled, “The Beauty and Science of Lenticular Clouds: Hidden Waves and Secret Vortexes,” scheduled for Thursday, May 3, at 7 p.m. at Mt. Shasta Sisson Museum.
Have you ever wondered why amazing cloud shapes are often seen over Mount Shasta? What causes them? When are they more likely to be seen? Miesse will answer these questions and more.
According to Miesse, “This is mostly a natural science presentation describing and explaining some of the lesser-known aspects of Mount Shasta’s lenticular clouds. Lenticular clouds result from complicated-sounding concepts like ‘Gravity Waves,’ ‘Vertically Propagating Waves,’ ‘Rotors,’ ‘Convergence Zones,’ ‘Wave Trains,’ and ‘Hydraulic Jumps.’ But actually, these things are pretty easy to understand through pictures, so that’s what we’ll show.
“Plus, we’ll do a brief review of all major cloud types to help understand why lenticular clouds and associated rotor clouds are considered much rarer. I’ll add a few photos of other rare local clouds, like mammatus clouds, pileus clouds, and fall-streak clouds; all of them can be seen around the mountain from time to time,” Miesse said.
In addition, Miesee will do a brief review of the role of the lenticular clouds in developing Mount Shasta’s mystical reputation.
Miesse related that this presentation will include “at least half a dozen local videos that haven’t been shown before, and which illustrate some of the atmospheric phenomenon like rotor clouds and wave trains that we’ll be talking about.”
As for any current research that Miesse will be sharing, “Who said that the Shasta Vortex isn’t real? I think ‘Vortex Shredding’ is something new to me and very interesting. It is where a wind spiral is generated off of the slopes of the mountain and then twists up through the veil of a lenticular cloud above Mount Shasta.”
The popular subject of lenticular clouds has been an exhibit at Mt. Shasta Sisson Museum for several years. This year, the museum, Snow Creek Studios, and Miesse produced a new video that includes the beauty and the science of lenticular clouds.
Museum Director Jean Nels says numerous people enjoy viewing and photographing these spectacular clouds, and they often ask the museum staff questions about them. Because of this continued interest and many requests, Miesse has agreed to give this new presentation.
A $5 donation is requested. All proceeds from the presentation will go toward the museum and its mission of “Illuminating the Past, Present, and Future of the Mount Shasta Region.”
