A scalar potential is also just a harmonic assembly of bidirectional longitudinal EM wavepairs, as shown in a paper by E.T. Whittaker the year before, 1903. So one can produce the necessary longitudinal waves, in arrays, to "assemble" a scalar potential with any desired interior LW composition. Thus by using longitudinal EM waves (LWs), one can produce potentials, fields, and waves to order. It turns out that a longitudinal EM wave, since it cannot vary transversely a priori, cannot vary its 3-spatial energy density. Instead, it must vary in the time domain. What results is that one has created an oscillation of the curvature of spacetime, when one makes a longitutinal EM wave.
Now one can engineer clusters of ST curvatures, by proper assembly of LWs. This is a very powerful general relativity, because the strong EM force is being used as the agent of ST curvature. This particular EM GR does not appear in the textbooks, but has been utilized by the Russian KGB in clandestine weapon development since the 1950s.

Here's how the weather engineering is usually accomplished:
First, take two scalar potential beam transmitters, separated on the necessary baseline to form a beam interferometer. Let them interfere at a distance. Now in that distant interference zone (IZ), there is an ambient vacuum potential (spacetime potential, or spacetime stress). If the electrical circuit grounds of the interferometer transmitters are biased ABOVE the ambient potential in the IZ, then scattering EM energy (heating) emerges in the IZ. This is the exothermic mode of operation. If the electrical circuit grounds of the interferometer are biased negatively below the ambient potential in the IZ, then convergent EM energy (cooling) emerges in the IZ. This is the endothermic mode of operation.
So by merely biasing the electrical grounds of a scalar potential interferometer, one can produce heating or cooling in the distant IZ. If one just "radiates," one produces distant steady heating or steady cooling. If one sharply pulses the interferometer, one produces a distant hot explosion or a distant cold explosion.
One can also, of course, form various forms of energy at a distance, including particularly hemispheric shells of energy and spherical shells of energy. Hundreds of these have been observed worldwide, from testing by the KGB weapons in Russia.
There is one other characteristic that one needs to be aware of. Pure longitudinal EM waves have infinite speed and infinite velocity (see the summary papers by Rodrigues et al. on the Los Alamos National Laboratory website). In practice one makes a pseudo-longitudinal wave, so its energy is finite and its speed is finite, but it may have a velocity v>>c.
A "scalar" potential is not a scalar entity at all. Instead, it's a bundle of bidirectional longitudinal waves, as shown by Whittaker 1903. Mass is composed mostly of empty space filled with potentials and fields, with a particle here and there, widely separated. On its own scale, a "mass" looks more like a giant solar system or the external universe. Mostly space, with fields and potentials. Well, since fields and potentials are nothing but just LWs anyway (W-1903 and 1904), then the stress potential of space is a superhighway for LWs. What this means is that "pretty good" LWs (i.e., sufficiently clean pseudo longitudinal waves) will pass right through the earth and ocean, with little attenuation and little interaction.

Now we are ready to see into weather engineering.
Focus the interference zone (IZ) on the other side of the earth (beam right through the earth and ocean) to a given desired area in the atmosphere. Bias your transmitters positively. You produce atmospheric heating in the air in the IZ, so that the air expands and you have produced a "low" pressure zone. Now use a second interferometer biased negatively, and place it at a distant IZ desired. In that IZ, you cool the air so that it shrinks and becomes denser, and you have created a "high" pressure area. Now place several such IZs, with the desired highs and lows, near a jet stream. The jet stream will be deviated toward a low and away from a high. By varying the transmitted energy and the iz location (just move it gradually along), you can entrain and steer the jet streams, and therefore effectively "steer" the resulting weather. 
Want to spawn tornadoes? Just make several sharp bends in the jet streams, and also speed them up a bit. The additional angular momentum imparted to the air masses will spawn off littler rotations (tornadoes). By focusing the IZ underneath the ocean, one can heat or cool the water in a selected area, over a period of time. So you can aggravate or ease El Nino, e.g. By proper steering and coordination around the earth, the KGB is able to create a great deal of rain in an area, a drought in an area, storms and tornadoes, a powerful El Nino, etc.

Want to really mess with the troops? Just focus the IZ in a large fault zone -- say such as the San Andreas fault in California. Use the exothermic interferometry mode. You deposit energy slowly in that fault zone. The stress increases. Eventually the plate edges shift, and you have an earthquake. If you want a very powerful quake, put the energy in gradually, so that a sort of "overpotential" or "overpressure" builds up, past where the rocks would normally slip. Then when they let go, you've got a real nice big one. You can see what might happen if one also toys around with a sleeping volcano.

On July 4, 1976 the KGB began its massive and continuing weather engineering over North America. It continues to this day. So the anomalous weather everyone is worrying about, is going to STAY anomalous. In fact, it's going to get a bit worse.There's a whole war going on out there.
It might surprise you, e.g., that electrodynamics actually has nothing at all to say about the form of its EM entities in space, where there is no mass. Maxwell assumed a material ether, and all his EM entities are mass-containing. The force fields are rigorously defined only in the presence of mass, and only as the INTERACTION of the spacetime disturbance with an intercepting charged mass. So Maxwell's EM still contains a material ether, even though the Michelson-Morley experiments destroyed a material space medium in the 1880s (after Maxwell was already dead). Not a single Maxwellian equation has been changed!
Rigorously, Maxwellian EM is a set of matter-to-matter transforms. Actually infolded inside its transforms are a missing two: (1) matter-to-spacetime transform, which is really what is invoked when one launches a "signal" from a transmitter; one launches a spacetime curvature oscillation, not a force field oscillation, because no force fields exist in space in the absence of mass (Feynman, Wheeler, Aharonov, Bohm, Lindsay, Margenau, etc.) Then the ST perturbation propagates through space to the waiting receiving antenna. There it interacts with the Drude electrons, producing the well-known transverse EM oscillations. Since the electrons are constrained longitudinally down the wire and are spinning, they act as gyros. So they precess laterally, which is actually what we measure with our instruments -- the gyroprecession of the charges. So hidden inside the matter-to-matter EM they erroneously teach us, is an infolded general relativity (a matter-to-spacetime transform, followed by a spacetime-to-matter transform in serial order).
This is the "magical" unified field theory everyone has been seeking. The electrodynamics we teach is a piece of tripe, and the Russians just secretly corrected it back in the early 50s. And then they weaponized the daylights out of it. Today at least three other nations besides the KGB rogue group in Russia have scalar potential interferometer weapons. The weather engineering is just one of the EARLY capabilities. The most powerful weapons on earth are not nuclear. They are quantum potential in nature, using a modified Whittaker EM to implement David Bohm's hidden variable theory of quantum mechanics.
Meanwhile, since our own electrical physicists have rather thoroughly failed us, and just keep teaching the horribly flawed old electrodynamics, we will continue to watch as the weather is hostilely engineered, as even earthquakes are engineered from time to time, and as another small nation which must remain unnamed, saves us and prevents our destruction.

Didn't know whether such things would even interest you, but thought I'd expose them anyway. Most scientists are very uncomfortable with even the notion that something substantial is wrong with our physics texts. But such is true. Until we do the necessary foundations overhaul, we will continue to teach and use a highly inferior science. And we will continue to see more and more anomalous weather. Incidentally, the KGB weapon scientists call the infolded LWs (curvatures of ST) inside electrodyamics, the information content of the field. Our guys just think they are referring to spectral analysis. The Russians call the entire science energetics.
You can see the earlier version of the Rodrigues paper in Foundations of Physics, 27(3), 1997, p. 435-508. Whittaker's papers are: (1) "On an expression of the Electromagnetic Field Due to Electrons by Means of Two Scalar Potential Functions," Proc. Lond. Math. Soc., Series 2, Vol. 1, 1904, p. 367-372; (2) "On the Partial Differential Equations of Mathematical Physics," Math. Ann., Vol. 57, 1903, p. 333-355. A summary of superpotential theory is given by Melba Phillips, "Classical Electrodynamics," Vol IV of Principles of Electrodynamics and Relativity, Ed. by S. Flugge, Springer-Verlag, Berlin, 1962, p. 1-108. Other scientists such as Debye, Nisbet, Bromwich, and McCrea contributed to the foundations of superpotential theory. An excellent and eye-opening paper is Patrick Cornille, "Inhomogeneous Waves and Maxwell's Equations," Chap. 4 in Essays on the Formal Aspects of Electromagnetic Theory, World Scientific, Singapore, 1992, p. 6-86. Highly recommended is T.W. Barrett and D.M. Grimes, Eds., Advanced Electromagnetism: Foundations, Theory, & Applications, World Scientific, New Jersey, 1995.

For a test of a superweapon, see Walker et al, "Kaitoku Seamount and the Mystery Cloud of 9 April 1984," Science, Vol. 227, Feb. 8, 1985, p. 607-6111. See also Daniel L. McKenna and Daniel Walker, "Mystery Cloud: Additional Observations," Science, Vol. 234, Oct. 24, 1986, p. 412-413. That incident on April 9, 1984 off the coast of Japan and near the Kuriles, was a huge test of (1) a cold explosion just over the surface of the ocean, which suddenly shrank the air so that surrounding air rushed in, meeting and surging upwards into the sky, entraining lots of water as a mist and dense cloud with it. Then a second test was conducted: a glowing sphere of light appeared in the top of the large mushroom cloud from the cold explosion. Then that spherical globe expanded, until it reached some 380 miles in diameter. The center of the globe at that time was about 200 miles altitude. That is written up in two fine articles in the respected journal Science.
This is the scale the KGB has been operating on, with these interferometry weapons. There are hundreds more such incidents or similar. Anyhow, thanks for sending me the updates on the actual weather occurrences. They do help from time to time.
