This was posted in Flat Earth Media but that is hardly to forum for further discussion so I have started this new topic.
The following references might be useful:
Calculating Ray Bending This gives a simplistic calculation of the lapse rate needed to cause ducting.
Ducts More specific discussion of ducts, with diagrams.
Marine layer Discusses the "marine layer", common in the Monterey Bay area.
Monterey Bay National Marine Sanctuary, Regional pressure and temperature effects.
Maybe someone can make something of that material.
Now I'm no meteorologist but an explanation might be atmospheric ducting due to a temperature inversion. This is not uncommon in that region.Even with very strong atmospheric refraction, I don't think this should be possible on a globe:
I look forward to seeing this done again across greater expanses. I need to see if this is repeatedly under standard conditions. In fact, I want to do it myself. I have no answer for this and concede this strongly supports a flat earth...for the time being.
I can see globies are ignoring such a great visual scientific experiment. If the experiment does not prove a curve they want nothing to do with it.
I wonder what their argument will be?

Atmospheric ductThese are also relevant:
Fata Morgana of Farallon Islands with clearly seen duct
In telecommunications, an atmospheric duct is a horizontal layer in the lower atmosphere in which the vertical refractive index gradients are such that radio signals (and light rays) are guided or ducted, tend to follow the curvature of the Earth, and experience less attenuation in the ducts than they would if the ducts were not present. The duct acts as an atmospheric dielectric waveguide and limits the spread of the wavefront to only the horizontal dimension.
Atmospheric ducting is a mode of propagation of electromagnetic radiation, usually in the lower layers of Earth’s atmosphere, where the waves are bent by atmospheric refraction. In over-the-horizon radar, ducting causes part of the radiated and target-reflection energy of a radar system to be guided over distances far greater than the normal radar range. It also causes long distance propagation of radio signals in bands that would normally be limited to line of sight.
Normally radio "ground waves" propagate along the surface as creeping waves. That is, they are only diffracted around the curvature of the earth. This is one reason that early long distance radio communication used long wavelengths. The best known exception is that HF (3–30 MHz.) waves are reflected by the ionosphere.
The reduced refractive index due to lower densities at the higher altitudes in the Earth's atmosphere bends the signals back toward the Earth. Signals in a higher refractive index layer, i.e., duct, tend to remain in that layer because of the reflection and refraction encountered at the boundary with a lower refractive index material. In some weather conditions, such as inversion layers, density changes so rapidly that waves are guided around the curvature of the earth at constant altitude.
