Solar magnetic field reversal
Strong toroidal magnetic fields (TMF) forming Active Regions (ARs)
are created in a shear layer beneath the base of the Solar Convection zone
(SCZ).

The
increases
of terrestrial temperat
ure
will be
interrupted by the decreases by 1C
during two
GSMs
(2020-2053 and 2375-2415)
caused by large reduction of solar activity.
Solar magnetic field reversal, wavelet spectral analysis, and proxies for solar activity index are discussed in relation to the joint effects of solar activity and solar orbital motion on the Earth's atmosphere. The study highlights the impact of solar cycles on terrestrial climate dynamics and temperature variations, projecting a decrease in temperature following the Sun entering a grand solar minimum until 2053. Observational results and dynamo models further support the findings.

Variations of the total annual TSI in M1 (600-1600) and M2 (1600-2600) taken from the TSI averaged for each month (left) and daily TSI (right) https://arxiv.org/pdf/2008.00439.pdf Zharkova et al, 2019, Zharkova, 2020 Extra solar forcing Not considered so far! Extra 5 W/m2 of TSI, 60% warming comes to Sun, 40% - to green house gasses (Hardy, 2017). We have found extra TSI of 20 W/m2 in 2020! It will last until 2500!
Solar inertial motion effects Period of 2100-2200 years Solar dynamo effects: a) two double dynamo 11 year waves b) grand solar cycles & GSMs wave beating increase of T by 1.5C by 2100, and by further by 2.5-3.0 C by 2500 interrupted by T decreases during GSMs . During GSMs: a decrease of temperature up to 1C
Conclusions Solar activity is defined by action of solar dynamo converting solar poloidal (background) into toroidal (sunspot) magnetic fields and vice versa during the period of 10.7 years Solar dynamo acts in two layers with different speed of meridional circulation as derived from the summary curve of eigen vectors varying with the periods of 21.5 years (magnetic solar cycle) and 344-350 years (grand solar cycle) Spectral analysis of the TSI variations reveals the periods 2243 -2300 years (wavelet+Fourier) Hallstatt s cycles The baseline of the summary curve of SBMF also reveals weak variations with a period of ~2100- 2200 years Hallstatt s cycle Hallstatt s cycle variations are closely linked to the solar inertial motion (SIM) about the barycentre of the solar system the ephemeris of S-E distances shown A change of S-E distances from 1600 to 2500 leads to the TSI increase by 20-25 W/m2 per year (10-12 W/m2 per hemisphere) Increase of TSI with a decrease of S-E distances (SIM) leads to the increase of T by 1.5C by 2100, and by further by 2.5-3.0 C by 2500. The increases of terrestrial temperature will be interrupted by the decreases by 1C during two GSMs (2020-2053 and 2375-2415) caused by large reduction of solar activity.
