Volcanic eruption

How good is the evidence for such a connection, and what theories do we have? Does a really low solar minimum – like now – make a difference? Here’s PW’s overview of its article.

Over the long term, the sun is the main driver of weather and climate on Earth and it is also directly connected to such phenomenon as the aurora borealis also known as the northern lights, upper atmospheric “high-latitude blocking”, and the influx of cosmic rays into Earth’s atmosphere, says Perspecta Weather.

The aurora borealis tends to occur more often during times of increased solar activity though they can actually take place at any time of a solar cycle.

On the other hand, there is a tendency for more frequent high-latitude blocking events in the atmosphere during periods of low solar activity and these episodes can play an important role in winter weather conditions across the central and eastern US.

The influx of cosmic rays into the Earth’s atmosphere from outer space tends to increase dramatically during solar minimums which we are experiencing at the current time.

Interestingly, there is evidence that solar activity plays a role in volcanic activity on our planet.

In fact, in times of low solar activity such as during the current solar minimum, volcanic activity tends to rise.

Indeed, there has been a significant amount of volcanic activity in recent weeks including the latest eruption in the Philippines.

    ‘Scientists say’ lots of things.

    Looks to me like volcanic activity happens during the solar transition periods.

    Charvatova’s Solar Inertial Motion (SIM) hypothesis – similar SIM curves yield similar solar activity

    An exciting twist to a 150-year model for solar activity has been presented by Ivanka Charvatova of the Institute of Geophysics in Praha, the Czech Republic. While she still works on physics based models to establish a link between sun-barycenter movements (as have many others), she has proposed that periods of similar SIM curves would have similar solar activity. This gives a simple but powerful, phenomenlogically uncommitted way of testing for a correlation between SIM and solar activity, beyond past approaches.

    Given the limited amount of sunspot data (~300 or 400 years, with quality data for only 150 years, and a basic SIM period of 178 years), there are only a couple of periods that have been compared, and the results are striking. Phasing is especially good, and the current years and projections are covered.

    We know that the sun’s gravity affects the Earth – we orbit the sun. We know that the suns gravity is strong enough even at vast distances to have created the planets out to at least Neptune. So if the sun’s gravity changes slightly over time, it is surely possible that that could affect the Earth’s core? So does the sun’s mass change over time?

    Sun loses huge amounts of mass every second. Basic science.

    Turkey earthquake: People trapped as 22 killed and 1,200 injured
    Saturday 25 January 2020 17:47, UK

    At least 22 people have been killed after an earthquake with a magnitude of 6.8 struck eastern Turkey.

    October could be the final choice IMO, but it’s a bit academic with a series of very low sunspot months.
