CMEs Affect Earth Weather

[Maol]

I think CMEs and other mass and energy arriving with the solar wind have significant effect on terrestrial weather, heavy rain fall or ice fall, jet stream, surface winds, heat, cold, etc.

Can someone offer an opinion.

THE CME HAS ARRIVED AND STORMS ARE UNDERWAY: A halo CME struck Earth's magnetic field on June 1st at 0542 UTC. The impact sparked a series of strong (G3) to severe (G4) geomagnetic storms, which are still underway more than 12 hours later. So far, Northern Lights have been photographed as far south as latitude +30 N on the beaches of the Gulf of Mexico. Aurora alerts: SMS Text

Jay Shaffer photographed the display from Tres Piedras, New Mexico (latitude +36.6 N):

CME's would certainly have an effect upon Earth's weather. Of course the obvious effect from the Sun, is heat, but after that the "solar wind" (which is a euphemism for the dreaded phrase: electric current) certainly has an effect upon Earth's weather, and a CME can have a direct deleterious effect on Earth's weather and if there is a direct hit from a powerful enough CME, it can be a disaster, like the Carrington Event or worse.

Electric Weather

Perhaps I should have emphasized MASS a little more. I think in addition to the Sun's radiant heat the elemental oxygen and hydrogen in the CMEs and solar wind combine to form and deposit millions of tons of H2O in Earth's atmosphere and with that mass impart inertial and thermal effects which influence the weather patterns.

One million tons of water is approximately a 100 meter cube. A CME can be several billion tons of mass and Oxygen is the third most abundant element in the Sun

I've been saying for at least 30 years that this is obvious, that flares and particularly CMEs, with billions of tons of mass, mostly protons, but of which millions of tons are Oxygen ions, that whatever portion of the mass of a CME that impinges Earth's magnetic field, some of that mass of H and O will get into the magnetotail in the shadow and cool to below ionization temperature, gather electrons and when the (we've all seen the video imagery) magnetotail blobs stretch downwind and snap back to deposit the mass to the poles and aurora results, the H and O and electrons have got to combine into H2O and OH radicals, etc, and by this means water enters the Earth's atmosphere. So simple that if a caveman were an astrophysicist he could understand it.

Solar flares may change the weather on distant worlds—and maybe even ours

"Published in The Astronomical Journal, the study offers the clearest evidence yet that space weather—particularly flares from a planet's host star—can cause measurable changes in a planet's climate within just days of an event."
