*I realized you keep quoting Lord Rayleigh who died a hundred years ago. *The barometer pressure paradox stands unsolved to this very day.

*From the World Meteorological Organization: "The interpretation of day-night differences must allow for real daily variation in geopotential height caused by diurnal and semidiurnal tides. Real day-night differences at mid-latitudes for 100 hPa geopotential heights can be as large as 30 m between observations at 1800 and 0600 local time (Nash, 1984), whereas real day-night differences between observations at 1200 and 0000 local time will usually be in the range 0 ± 10 m."* You are still dodging the main issue.

"The temperature produced by the sun on the surface of the earth, as measured by the thermometer, is increased during the former part of the day and progressively diminished during the latter part and the night, as follows: it begins to rise a little before the sun, increases until about one o'clock in the day, when it turns and declines; and continues falling until about five o'clock the next morning — making but one rise of eight, and one fall of sixteen, in the twenty-four hours. From these facts it sufficiently appears that the two daily atmospheric tides or movements cannot be caused directly by the sun heating the surface of the earth.

Here are the facts:

BAROMETER PRESSURE PARADOX

One maximum is at 10 a.m., the other at 10 p.m.; the two minima are at 4 a.m. and 4 p.m.

**The heating effect of the sun can explain neither the time when the maxima appear nor the time of the minima of these semidiurnal variations.**If the pressure becomes lower without the air becoming lighter through a lateral expansion due to heat, this must mean that the same mass of air gravitates with changing force at different hours.

There is only one other element of weather which features a semidiurnal oscillation: atmospheric electricity.

Since terrestrial gravity is directly linked to electricity, the barometer pressure phenomenon is in direct relationship to the electric potential.

The potential variation is the cause of the barometer pressure oscillations:

A much higher form of relativity is, as an example, the Reissner-Nordstrom metric:

In order to reach the final formula, H. Weyl states:

"In this context, the energy-momentum tensor will be comprised only of that valid for

**the electromagnetic field in the æther** and of the “kinetic” energy-momentum tensor of the matter in the more restricted sense."

"Weyl’s new geometry was much richer than the Riemannian geometry in both its mathematical and philosophical content. Mathematically, the new geometry introduced new quantities into space that had no analogy in other geometries. Philosophically, these new quantities, unaccounted for by Riemannian geometry and thus unaccounted for in General Relativity, were used by Weyl to represent electromagnetic phenomena. Every point in space, represented by a vector having both magnitude and direction, could be displaced to another point in the same space yielding electromagnetism. When only the direction of the vector was taken into account, ignoring the vector’s magnitude, there remained a parallel displacement of the kind described by Levi-Civita, which accounted for gravity. The difference with Weyl’s geometry lay in the fact that it was no longer necessary for a vector’s magnitude or length to remain constant while being displaced between points in space."

“Later the quantum-theory introduced the Schrodinger-Dirac potential ψ of the electron-positron field; it carried with it an experimentally based principle of gauge-invariance which guaranteed the conservation of charge, and connected the ψ with the electromagnetic potentials Aµ in the same way that my speculative theory had connected the gravitational potentials gµν with the Aµ, and measured the Aµ in known atomic, rather than unknown cosmological units."
